Explain Kotlin's five scope functions: let, run, with, apply, also
This tests your grasp of idiomatic Kotlin. A great answer categorizes functions by their context object (`this`/`it`) and return value (object/lambda result). Provide a clear use case for `apply` (object configuration).
This question tests your understanding of idiomatic Kotlin and code clarity, not just rote memorization. A strong answer first explains the two key differentiators: the context object (`this` vs. `it`) and the return value (the object vs. the lambda's result). Then, it groups the functions accordingly and provides a canonical use case for each, especially `apply` for object initialization. A common red flag is failing to articulate this framework or suggesting complex, nested scope function chains.
