[removed] Do I need to put this.var for every variable in an object?

Question

In C++, the language I\'m most comfortable with, usually one declares an object like this:

class foo
{
public:
    int bar;
    int getBar() { return bar; }
         


        

Answer 1

this is like a public access modifier of objects(variables or functions), while var is the private access modifier

Example

var x = {}; 
x.hello = function(){
    var k = 'Hello World'; 
   this.m = 'Hello JavaScript'; 
}

var t = new x.hello(); 
console.log(t.k); //undefined
console.log(t.m); //Hello JavaScript
