Answer

Both are scope functions, but they differ in object reference and return value.

apply

• Object Reference: `this`
• Return Value: The object itself.
• Use Case: Object configuration / initialization. "Apply these settings to the object."

```kotlin val intent = Intent().apply { action = Intent.ACTION_VIEW data = Uri.parse("https://google.com") } // Returns the configured Intent ```

with

• Object Reference: `this`
• Return Value: The result of the lambda (last line).
• Use Case: Performing multiple operations on an object without returning it. "With this object, do these things."

```kotlin val length = with(person) { println(name) println(age) name.length // Returns this Int } ```

Quick Rule

• Need the object back? Use apply.
• Need a result from the object? Use with (or run).
