They are a way to encapsulate a set of instructions, making code modular, reusable, and organized. Functions perform specific tasks or calculations and can accept input, perform operations, and return results. Here are the key components and concepts associated with JavaScript functions: Function Declaration: A function in JavaScript is declared using the function keyword, followed by a name for the function, a set of parentheses for parameters (if any), and a block of code enclosed in curly braces.

When you call the function, you provide actual values for these parameters, known as arguments. javascript Copy code function add(a, b) { return a + b; } const result = add(5, 3); // result will be 8 Return Statement: Functions can return values using the Parameters and Arguments: Functions can accept input values, called parameters, which are defined inside the parentheses during the function declaration. When you call the function, you provide actual values for these parameters, known as arguments.
