Trampoliny

Z komentarza:

rather than wrap the sumBelowRect body into an anonymous function, I’d simplify it with a .bind(), like so:

const sumBelowRec = (number, sum = 0) => ( number === 0 ? sum : sumBelowRec.bind(null, number — 1, sum + number) )

trampolines.js

var trampoline - function(fn) {
  return function() {
    var result = fn.apply(null, arguments);
    
    while (typeof result === 'function') {
      result = result();
    }
    
    return result;
  }
}

function doSomething(number, sum) {
  var x = sum || 0;
  
  return number === 0 ? x : function() {
    return doSomething(number -1, x + number);
  }
}

var checkAll = trampoline(doSomething);

doSomething(10);
