A function in JavaScript is a block of code designed to perform a specific task. All functions in JavaScript have a function name, a set of parentheses, and curly brackets that contain the code to be executed. Calling a function executes the code inside it and returns a value. To pass a function arguments means to provide values or variables to the function that it can use to perform its task. This allows for flexibility and reusability of the function. The purpose of the return keyword in functions is to specify the value that the function will return when it is called. Without a return statement, the function will execute but not provide any value back to the calling code. The return statement can also be used to terminate a function prematurely if necessary.
