/*
In line 4 of Javascript function, a semicolon is missing. Also, we cannot set up a function inside a for loop because
i in the function(x) referred a variable that belongs to the outside scope, the variable i is y.
*/

/* We can improve the code shown below: */
function f(num){
	return function(){
		x + num;
	};
}
function createArrayOfFunctions(y) {
  var arr = [];
  for(var i = 0; i<y; i++) {
    arr[i] = f(i) ;
  }
return arr;
