kotlinc code example

Example 1: kotlin also

| Function | Object reference | Return value   | Is extension function                        |
|----------|------------------|----------------|----------------------------------------------|
| let      | it               | Lambda result  | Yes                                          |

| run      | -                | Lambda result  | No: called without the context object        |
| with     | this             | Lambda result  | No: takes the context object as an argument. |
| apply    | this             | Context object | Yes                                          |

Example 2: kotlin vs java

Kotlin is a language built on and entirely backwards-compatible with Java.
While Java is Object-Oriented first, Kotlin supports a blend
of OO and functional paradigms. For further information, refer to
