Webb14 okt. 2024 · Functions are the main “building blocks” of the program. They allow the code to be called many times without repetition. We’ve already seen examples of built-in functions, like alert (message), prompt (message, default) and confirm (question). But we can create functions of our own as well. WebbWhat are Functions? Functions are an useful way to make reusable sections of code. If you have a bunch of code that is often repeated, instead of copying and pasting the code in many places you can just put it in a function then call the function when you need to run the code. In many cases this allows for cleaner code, reduces the complexity ...
