I have seen a main() function in some JavaScript files I have come across. Is it the same main function as you use in other languages such as C#, C++?? If you put a main function in your JS file, is that where the code starts executing? Or is it just another name used for a function?
I have searched the web but didn't find anything useful regarding this matter.

JavaScript Functions. JavaScript provides functions similar to most of the scripting and programming languages. In JavaScript, a function allows you to define a block of code, give it a name and then execute it as many times as you want.
Many programming languages require a special user-written function that marks the begin of the execution. For example, in C this function must always have the name main() . In JavaScript, however, such a function is not required.
The main() function is required so that the startup code knows where execution of your code should start.
The main() is just a wrapper being used by Node. js and stays in the call stack as long as the main (non-callback) part of the program is running. The function gets added to the stack, then the statements inside the function get added as they are called and removed as they are executed.
No, main is not the same in JavaScript as in C languages. It's just another function, but the original programmer is probably using the name as a convention to indicate where the code should start running.

"Main" function has nothing different then any other function (Its just a name). It will run when called and not automatically.
