1The code below is written using ES6 syntaxes but could just as easily be written in ES5 or even less. ES6 is not a requirement to create a "mechanism to loop x times"

3If you don't need the iterator in the callback, this is the most simple implementation

5const times = x => f => {
6  if (x > 0) {
7    f()
8    times (x - 1) (f)
9  }
10}

12// use it
13times (3) (() => console.log('hi'))
14
15// or define intermediate functions for reuse
16let twice = times (2)
17
18// twice the power !
19twice (() => console.log('double vision'))
