Convert code from es6 to es5? See example for the es6 code

I have the following code in es6 and I want to convert it to es5. 

class PowerArray extends Array {
  isEmpty() {
    return this.length === 0;
  }
}

let arr = new PowerArray(1, 2, 5, 10, 50);
console.log(arr.isEmpty()); // -> empty
console.log(arr.filter(item => item >= 10)); // -> 10, 50

I tried using Array.prototype.filter.call(context, callback), but I can't figure out what to pass in the first argument. Is it even possible to accomplish this?

I know I can use Babel, but this question is for learning purposes.
