'this' is undefined in JavaScript class methods

Question

I\'m new to JavaScript. New as far as all I\'ve really done with it is tweaked existing code and wrote small bits of jQuery.

Now I\'m attempting to write a \"class\"

Answer 1

I just wanted to point out that sometimes this error happens because a function has been used as a high order function (passed as an argument) and then the scope of this got lost. In such cases, I would recommend passing such function bound to this. E.g.

this.myFunction.bind(this);
