Null Safety\n\nKotlin'in tip sistemi nullable ve non-nullable tipleri ayırır. Tam olarak kullanın.\n\n```kotlin\n\u002F\u002F İyi: Varsayılan olarak non-nullable tipler kullan\nfun getUser(id: String): User {\n    return userRepository.findById(id)\n        ?: throw UserNotFoundException(\"User $id not found\")\n}\n\n\u002F\u002F İyi: Safe call'lar ve Elvis operatörü\nfun getUserEmail(userId: String): String {\n    val user = userRepository.findById(userId)\n    return user?.email ?: \"unknown@example.com\"\n}\n\n\u002F\u002F Kötü: Nullable tipleri zorla açma\nfun getUserEmail(userId: String): String {\n    val user = userRepository.findById(userId)\n    return user!!.email \u002F\u002F null ise NPE fırlatır\n}\n```\n\n### 2. Varsayılan Olarak Immutability\n\n`var` yerine `val` tercih edin, mutable koleksiyonlar yerine immutable olanları.\n\n```kotlin\n\u002F\u002F İyi: Immutable veri\ndata class User(\n    val id: String,\n    val name: String,\n    val email: String,\n)\n\n\u002F\u002F İyi: copy() ile dönüştürme\nfun updateEmail(user: User, newEmail: String): User =\n    user.copy(email = newEmail)\n\n\u002F\u002F İyi: Immutable koleksiyonlar\nval users: List\u003CUser> = listOf(user1, user2)\nval filtered = users.filter { it.email.isNotBlank() }\n\n\u002F\u002F Kötü: Mutable state\nvar currentUser: User? = null \u002F\u002F Mutable global state'ten kaçın\nval mutableUsers = mutableListOf\u003CUser>() \u002F\u002F Gerçekten gerekmedikçe kaçın\n```\n\n### 3. Expression Body'ler ve Tek İfadeli Fonksiyonlar\n\nKısa, okunabilir fonksiyonlar için expression body'ler kullanın.\n\n```kotlin\n\u002F\u002F İyi: Expression body\nfun isAdult(age: Int): Boolean = age >= 18\n\nfun formatFullName(first: String, last: String): String =\n    \"$first $last\".trim()\n\nfun User.displayName(): String =\n    name.ifBlank { email.substringBefore('@') }\n\n\u002F\u002F İyi: Expression olarak when\nfun statusMessage(code: Int): String = when (code) {\n    200 -> \"OK\"\n    404 -> \"Not Found\"\n    500 -> \"Internal Server Error\"\n    else -> \"Unknown status: $code\"\n}\n\n\u002F\u002F Kötü: Gereksiz block body\nfun isAdult(age: Int): Boolean {\n    return age >= 18\n}\n```\n\n### 4. Value Objeler İçin Data Class'lar\n\nÖncelikle veri tutan tipler için data class'lar kullanın.\n\n```kotlin\n\u002F\u002F İyi: copy, equals, hashCode, toString ile data class\ndata class CreateUserRequest(\n    val name: String,\n    val email: String,\n    val role: Role = Role.USER,\n)\n\n\u002F\u002F İyi: Tip güvenliği için value class (runtime'da sıfır maliyet)\n@JvmInline\nvalue class UserId(val value: String) {\n    init {\n        require(value.isNotBlank()) { \"UserId cannot be blank\" }\n    }\n}\n\n@JvmInline\nvalue class Email(val value: String) {\n    init {\n        require('@' in value) { \"Invalid email: $value\" }\n    }\n}\n\nfun getUser(id: UserId): User = userRepository.findById(id)\n```\n\n## Sealed Class'lar ve Interface'ler\n\n### Kısıtlı Hiyerarşileri Modelleme\n\n```kotlin\n\u002F\u002F İyi: Exhaustive when için sealed class\nsealed class Result\u003Cout T> {\n    data class Success\u003CT>(val data: T) : Result\u003CT>()\n    data class Failure(val error: AppError) : Result\u003CNothing>()\n    data object Loading : Result\u003CNothing>()\n}\n\nfun \u003CT> Result\u003CT>.getOrNull(): T? = when (this) {\n    is Result.Success ->

error.toException()\n    is Result.Loading -> throw IllegalStateException(\"Still loading\")\n}\n```\n\n### API Yanıtları İçin Sealed Interface'ler\n\n```kotlin\nsealed interface ApiError {\n    val message: String\n\n    data class NotFound(override val message: String) : ApiError\n    data class Unauthorized(override val message: String) : ApiError\n    data class Validation(\n        override val message: String,\n        val field: String,\n    ) : ApiError\n    data class Internal(\n        override val message: String,\n        val cause: Throwable? = null,\n    ) : ApiError\n}\n\nfun ApiError.toStatusCode(): Int = when (this) {\n    is ApiError.NotFound -> 404\n    is ApiError.Unauthorized -> 401\n    is ApiError.Validation -> 422\n    is ApiError.Internal -> 500\n}\n```\n\n## Scope Fonksiyonlar\n\n### Her Birini Ne Zaman Kullanmalı\n\n```kotlin\n\u002F\u002F let: Nullable'ı veya scope edilmiş sonucu dönüştür\nval length: Int? = name?.let { it.trim().length }\n\n\u002F\u002F apply: Bir nesneyi yapılandır (nesneyi döndürür)\nval user = User().apply {\n    name = \"Alice\"\n    email = \"alice@example.com\"\n}\n\n\u002F\u002F also: Yan etkiler (nesneyi döndürür)\nval user = createUser(request).also { logger.info(\"Created user: ${it.id}\") }\n\n\u002F\u002F run: Receiver ile block çalıştır (sonucu döndürür)\nval result = connection.run {\n    prepareStatement(sql)\n    executeQuery()\n}\n\n\u002F\u002F with: run'ın extension olmayan formu\nval csv = with(StringBuilder()) {\n    appendLine(\"name,email\")\n    users.forEach { appendLine(\"${it.name},${it.email}\") }\n    toString()\n}\n```\n\n## Extension Fonksiyonlar\n\n### Inheritance Olmadan Fonksiyonalite Ekleme\n\n```kotlin\n\u002F\u002F İyi: Domain'e özgü extension'lar\nfun String.toSlug(): String =\n    lowercase()\n        .replace(Regex(\"[^a-z0-9\\\\s-]\"), \"\")\n        .replace(Regex(\"\\\\s+\"), \"-\")\n        .trim('-')\n\nfun Instant.toLocalDate(zone: ZoneId = ZoneId.systemDefault()): LocalDate =\n    atZone(zone).toLocalDate()\n\n\u002F\u002F İyi: Koleksiyon extension'ları\nfun \u003CT> List\u003CT>.second(): T = this[1]\n\nfun \u003CT> List\u003CT>.secondOrNull(): T? = getOrNull(1)\n\n\u002F\u002F İyi: Scope edilmiş extension'lar (global namespace'i kirletmez)\nclass UserService {\n    private fun User.isActive(): Boolean =\n        status == Status.ACTIVE && lastLogin.isAfter(Instant.now().minus(30, ChronoUnit.DAYS))\n\n    fun getActiveUsers(): List\u003CUser> = userRepository.findAll().filter { it.isActive() }\n}\n```\n\n## Coroutine'ler\n\n### Yapılandırılmış Eşzamanlılık\n\n```kotlin\n\u002F\u002F İyi: coroutineScope ile yapılandırılmış eşzamanlılık\nsuspend fun fetchUserWithPosts(userId: String): UserProfile =\n    coroutineScope {\n        val userDeferred = async { userService.getUser(userId) }\n        val postsDeferred = async {

catch (e: Exception) {\n                emptyList()\n            },\n        )\n    }\n```\n\n### Reactive Stream'ler İçin Flow\n\n```kotlin\n\u002F\u002F İyi: Uygun hata işleme ile cold flow\nfun observeUsers(): Flow\u003CList\u003CUser>> = flow {\n    while (currentCoroutineContext().isActive) {\n        val users = userRepository.findAll()\n        emit(users)\n        delay(5.seconds)\n

Varsayılan Olarak Immutability\n\n`var` yerine `val` tercih edin, mutable koleksiyonlar yerine immutable olanları.\n\n```kotlin\n\u002F\u002F İyi: Immutable veri\ndata class User(\n    val id: String,\n    val name: String,\n    val email: String,\n)\n\n\u002F\u002F İyi: copy() ile dönüştürme\nfun updateEmail(user: User, newEmail: String): User =\n    user.copy(email = newEmail)\n\n\u002F\u002F İyi: Immutable koleksiyonlar\nval users: List\u003CUser> = listOf(user1, user2)\nval filtered = users.filter { it.email.isNotBlank() }\n\n\u002F\u002F Kötü: Mutable state\nvar currentUser: User? = null \u002F\u002F Mutable global state'ten kaçın\nval mutableUsers = mutableListOf\u003CUser>() \u002F\u002F Gerçekten gerekmedikçe kaçın\n```\n\n### 3. Expression Body'ler ve Tek İfadeli Fonksiyonlar\n\nKısa, okunabilir fonksiyonlar için expression body'ler kullanın.\n\n```kotlin\n\u002F\u002F İyi: Expression body\nfun isAdult(age: Int): Boolean = age >= 18\n\nfun formatFullName(first: String, last: String): String =\n    \"$first $last\".trim()\n\nfun User.displayName(): String =\n    name.ifBlank { email.substringBefore('@') }\n\n\u002F\u002F İyi: Expression olarak when\nfun statusMessage(code: Int): String = when (code) {\n    200 -> \"OK\"\n    404 -> \"Not Found\"\n    500 -> \"Internal Server Error\"\n    else -> \"Unknown status: $code\"\n}\n\n\u002F\u002F Kötü: Gereksiz block body\nfun isAdult(age: Int): Boolean {\n    return age >= 18\n}\n```\n\n### 4. Value Objeler İçin Data Class'lar\n\nÖncelikle veri tutan tipler için data class'lar kullanın.\n\n```kotlin\n\u002F\u002F İyi: copy, equals, hashCode, toString ile data class\ndata class CreateUserRequest(\n    val name: String,\n    val email: String,\n    val role: Role = Role.USER,\n)\n\n\u002F\u002F İyi: Tip güvenliği için value class (runtime'da sıfır maliyet)\n@JvmInline\nvalue class UserId(val value: String) {\n    init {\n        require(value.isNotBlank()) { \"UserId cannot be blank\" }\n    }\n}\n\n@JvmInline\nvalue class Email(val value: String) {\n    init {\n        require('@' in value) { \"Invalid email: $value\" }\n    }\n}\n\nfun getUser(id: UserId): User = userRepository.findById(id)\n```\n\n## Sealed Class'lar ve Interface'ler\n\n### Kısıtlı Hiyerarşileri Modelleme\n\n```kotlin\n\u002F\u002F İyi: Exhaustive when için sealed class\nsealed class Result\u003Cout T> {\n    data class Success\u003CT>(val data: T) : Result\u003CT>()\n    data class Failure(val error: AppError) : Result\u003CNothing>()\n    data object Loading : Result\u003CNothing>()\n}\n\nfun \u003CT> Result\u003CT>.getOrNull(): T? = when (this) {\n    is Result.Success -> data\n    is Result.Failure -> null\n    is Result.Loading -> null\n}\n\nfun \u003CT> Result\u003CT>.getOrThrow(): T = when (this) {\n    is Result.Success -> data\n    is Result.Failure -> throw error.toException()\n    is Result.Loading -> throw IllegalStateException(\"Still loading\")\n}\n```\n\n### API Yanıtları İçin Sealed Interface'ler\n\n```kotlin\nsealed interface ApiError {\n    val message: String\n\n    data class NotFound(override val message: String) : ApiError\n    data class Unauthorized(override val message: String) : ApiError\n    data class Validation(\n        override val message: String,\n        val field: String,\n    ) : ApiError\n    data class Internal(\n        override val message: String,\n        val cause: Throwable? = null,\n    ) : ApiError\n}\n\nfun ApiError.toStatusCode(): Int = when (this) {\n    is ApiError.NotFound -> 404\n    is ApiError.Unauthorized -> 401\n    is ApiError.Validation -> 422\n    is ApiError.Internal -> 500\n}\n```\n\n## Scope Fonksiyonlar\n\n### Her Birini Ne Zaman Kullanmalı\n\n```kotlin\n\u002F\u002F let: Nullable'ı veya scope edilmiş sonucu dönüştür\nval length: Int? = name?.let { it.trim().length }\n\n\u002F\u002F apply: Bir nesneyi yapılandır (nesneyi döndürür)\nval user = User().apply {\n    name = \"Alice\"\n    email = \"alice@example.com\"\n}\n\n\u002F\u002F also: Yan etkiler (nesneyi döndürür)\nval user = createUser(request).also { logger.info(\"Created user: ${it.id}\") }\n\n\u002F\u002F run: Receiver ile block çalıştır (sonucu döndürür)\nval result = connection.run {\n    prepareStatement(sql)\n    executeQuery()\n}\n\n\u002F\u002F with: run'ın extension olmayan formu\nval csv = with(StringBuilder()) {\n    appendLine(\"name,email\")\n    users.forEach { appendLine(\"${it.name},${it.email}\") }\n    toString()\n}\n```\n\n## Extension Fonksiyonlar\n\n### Inheritance Olmadan Fonksiyonalite Ekleme\n\n```kotlin\n\u002F\u002F İyi: Domain'e özgü extension'lar\nfun String.toSlug(): String =\n    lowercase()\n        .replace(Regex(\"[^a-z0-9\\\\s-]\"), \"\")\n        .replace(Regex(\"\\\\s+\"), \"-\")\n        .trim('-')\n\nfun Instant.toLocalDate(zone: ZoneId = ZoneId.systemDefault()): LocalDate =\n    atZone(zone).toLocalDate()\n\n\u002F\u002F İyi: Koleksiyon extension'ları\nfun \u003CT> List\u003CT>.second(): T = this[1]\n\nfun \u003CT> List\u003CT>.secondOrNull(): T? = getOrNull(1)\n\n\u002F\u002F İyi: Scope edilmiş extension'lar (global namespace'i kirletmez)\nclass UserService {\n    private fun User.isActive(): Boolean =\n        status == Status.ACTIVE && lastLogin.isAfter(Instant.now().minus(30, ChronoUnit.DAYS))\n\n    fun getActiveUsers(): List\u003CUser> = userRepository.findAll().filter { it.isActive() }\n}\n```\n\n## Coroutine'ler\n\n### Yapılandırılmış Eşzamanlılık\n\n```kotlin\n\u002F\u002F İyi: coroutineScope ile yapılandırılmış eşzamanlılık\nsuspend fun fetchUserWithPosts(userId: String): UserProfile =\n    coroutineScope {\n        val userDeferred = async { userService.getUser(userId) }\n        val postsDeferred = async { postService.getUserPosts(userId) }\n\n        UserProfile(\n            user = userDeferred.await(),\n            posts = postsDeferred.await(),\n        )\n    }\n\n\u002F\u002F İyi: child'lar bağımsız başarısız olabildiğinde supervisorScope\nsuspend fun fetchDashboard(userId: String): Dashboard =\n    supervisorScope {\n        val user = async { userService.getUser(userId) }\n        val notifications = async { notificationService.getRecent(userId) }\n        val recommendations = async { recommendationService.getFor(userId) }\n\n        Dashboard(\n            user = user.await(),\n            notifications = try {\n                notifications.await()\n            } catch (e: CancellationException) {\n                throw e\n            } catch (e: Exception) {\n

catch (e: Exception) {\n                emptyList()\n            },\n        )\n    }\n```\n\n### Reactive Stream'ler İçin Flow\n\n```kotlin\n\u002F\u002F İyi: Uygun hata işleme ile cold flow\nfun observeUsers(): Flow\u003CList\u003CUser>> = flow {\n    while (currentCoroutineContext().isActive) {\n        val users = userRepository.findAll()\n        emit(users)\n        delay(5.seconds)\n    }\n}.catch { e ->\n    logger.error(\"Error observing users\", e)\n    emit(emptyList())\n}\n\n\u002F\u002F İyi: Flow operatörleri\nfun searchUsers(query: Flow\u003CString>): Flow\u003CList\u003CUser>> =\n    query\n        .debounce(300.milliseconds)\n        .distinctUntilChanged()\n        .filter { it.length >= 2 }\n        .mapLatest { q -> userRepository.search(q) }\n        .catch { emit(emptyList()) }\n```\n\n## DSL Builder'lar\n\n### Tip Güvenli Builder'lar\n\n```kotlin\n\u002F\u002F İyi: @DslMarker ile DSL\n@DslMarker\nannotation class HtmlDsl\n\n@HtmlDsl\nclass HTML {\n    private val children = mutableListOf\u003CElement>()\n\n    fun head(init: Head.() -> Unit) {\n        children += Head().apply(init)\n    }\n\n    fun
