Writing and Using Functions in Node.js
Functions in Node.js are fundamental building blocks for structuring and organizing code. They enable modular programming by encapsulating reusable blocks of code, improving maintainability and readability. Functions can be declared using function declarations, function expressions, or arrow functions. They can accept parameters and return values, facilitating data manipulation and logic implementation. Functions can also be asynchronous, leveraging callbacks, promises, or async/await syntax to handle non-blocking operations.
This code demonstrates the use of different types of functions. It includes a function declaration, a function expression, and an arrow function for basic arithmetic operations. An asynchronous function simulates a delay. The calculate function showcases these functions, performs calculations, and demonstrates asynchronous behavior.
