What does it mean?
A function in web development is a block of code that performs a specific task and can be reused throughout a website or application. It is a fundamental building block of programming and allows developers to write code that is more efficient, organized, and easier to maintain. Functions can take in parameters, which are values that are passed into the function, and can return a value or perform an action. They can be called multiple times throughout a website or application, making them a powerful tool for developers. Functions can also be used to create more complex code structures, such as loops and conditional statements, which can help automate repetitive tasks and make code more dynamic. Overall, functions are an essential part of web development and are used extensively in modern web applications.
