Functions

Functions are fundamental building blocks in programming that allow developers to encapsulate code into reusable units. A function is essentially a named sequence of statements designed to perform a specific task. By defining functions, programmers can avoid code repetition, enhance readability, and simplify debugging. Functions can accept inputs, known as parameters, and can return outputs, making them versatile for various applications. In many programming languages, including Python and JavaScript, functions can be defined using specific syntax, and they can be called multiple times throughout a program, promoting efficient coding practices. Understanding functions is crucial for effective programming.
