## Answers

### Answer by Hitesh Vohra

- **[Functional](https://www.mindstick.com/articles/13005/the-functional-aspects-of-laser-technology) [programming](https://www.mindstick.com/articles/12214/web-development-company-in-india-laid-on-the-foundation-of-concrete-java-programming)** is a programming paradigm in which everything is bound using pure mathematical functions. It's a declarative programming approach. In contrast to an imperative style, which focuses on 'how to solve,' it focuses on 'what to solve.' Instead of statements, it use expressions. A statement is executed to assign variables, but an expression is evaluated to create a value.
- Functional programming is a programming paradigm in computer science in which programmes are built by applying and composing functions.
- It's a declarative programming paradigm in which function declarations are trees of expressions that map values to other values instead of a series of imperative statements that update the program's running state.
