Question

What does (this); mean on end of function in JavaScript?

I have a class with functions in it. Can I call this.outputSome within that class more times and/or when can I call it?

__construct = function(constructor){
    //some code
}(this);


this.outputSome = function(obj){
    //some
}(this);

Answer 1

It means that it executes itself with this as the parameter.

When you put parenthesis at the end of a function expression, it’s self executing, and executes after it has been defined. The fact that this is inside the parenthesis suggests that it is passing this as the parameter.
