how do I setInterval to call a function within a class

Question

I have a class like:

function run(){
this.interval;
this.start = function(){
    this.interval = setInterval(\'this.draw()\',1000);
};
this.draw = function()         


        

Answer 1

function run(){
    this.interval;
    this.start = function(){
        this.interval = setInterval(this.draw,1000);
    };
    this.draw = function(){
        //some code
    }
;} 

var run = new run();
run.start();
