JavaScript is a high-level, interpreted programming language used to create interactive websites and dynamic web applications. It is a popular language among programmers because of its versatility, ease-of-use, and support for object-oriented programming.

Features of JavaScript

Some key features of JavaScript include:

• Dynamic typing - variables can change data type during execution
• Prototypical inheritance - objects can inherit properties from other objects
• First-class functions - functions are treated as objects and can be passed as arguments and returned as values
• Closures - functions can access variables from their parent function even after the parent function has completed
• Asynchronous operations - code can be executed without waiting for a response from a server or user input

Examples

Here is an example of a basic JavaScript function that takes two numbers as arguments and returns their sum:

function add(num1, num2) {
  return num1 + num2;
}

We can call this function with:

console.log(add(2, 3)); // Output: 5
