What standard libraries do you use in Kotlin projects?

I use the following standard Kotlin libraries:

• kotlin-stdlib: Core classes and functions of the language, including collections, ranges, and extensions for basic types.
• kotlin-stdlib-jdk7 / kotlin-stdlib-jdk8: Extensions and adaptations for Java SE 7/8 API, such as working with streams (Stream) and CompletableFuture.
• kotlin-reflect: Functions for introspection and reflection at runtime.
• kotlin-coroutines-core: Basic components for coroutines, enabling asynchronous programming.
• kotlin-test: Framework for writing unit tests.

Depending on the platform, additional modules may be used:

• kotlin-stdlib-js: For Kotlin/JS.
• kotlin-stdlib-common: For Kotlin Multiplatform.

Example dependencies in build.gradle.kts:

dependencies {
    implementation(kotlin("stdlib"))
    implementation(kotlin("reflect"))
    implementation(kotlin("coroutines-core"))
    testImplementation(kotlin("test"))
}
