JavaScript Tutorial | Beginner | Function Declaration, Parameters, Arguments | Chap-4 | Part-1

After a long discussion on JavaScript's storage system-variables- and syntaxes, we shall start chapter four with functions. Chapter four will be dedicated entirely on explaining functions, functional behaviours and their states in JavaScript's scripts and programs. We will first take a conceptual look at how to declare a function when we want to create our own

functions. This first tutorial of chapter four will introduce two major concepts of function declarartion and invocation in JavaScript and the multiple ways in which both declarartion and invocation can be carried out when writing a programming script. After we learn function declaration, we shall move on to an in-depth understanding on parameters and arguments and then we will try to relate them with usual variable declaration and initialization.

Great Explanation. Can you please explain less, and actually do examples more. That helps getting the point across.

great explanation with the red pen, i think it gives good perspective, just out of interest, what country are you from? just interested because of your accent....
