If we have to put a function in JavaScript code, then we don't have to tell the function from the beginning what to do, we just have to write the name of our function in the code and the function will automatically be executed in our code.
All javascript coding is prebuilt coding because JavaScript functions are already declared. In simple words we do not need to tell the code how to do it, we just tell the code what to do.
JavaSccript is used by most web developers to make web pages more attractive. That is why JavaScript is also called client-side programming language because it works for a client or user.
Although there are many programming languages in the world, Javacropt is considered the most important programming language because JavaScript is an event-based programming language.
