   FULL Guide to Kotlin's Inline Keyword (inline, crossinline & noinline)

   This post explains the concept and benefits of using Kotlin's inline, crossinline, and noinline keywords. It demonstrates how inlining reduces function call overhead by copying function code directly into the caller's code. The post shows practical examples and scenarios where inline functions are beneficial, particularly for lambda functions and frequently called small functions. It also discusses how inline functions can maintain context, handle non-local returns, and work with generic types. Additionally, it touches on inline variables and classes such as value classes in Kotlin.
