Condense arrays with reduce: Challenge number 224

JavaScript
1

Tell us what’s happening:

Your code so far

var array = [4,5,6,7,8];
var singleVal = 0;

// Only change code below this line.

singleVal = array.reduce(function(singleVal, array){
  for(var i = 0; i < array.length; i++){
    singleVal += array[i];
  }
  return singleVal
});
Can anyone tell what is wrong with this code???

The Array.prototype.reduce function already adds all the items together within the function. THere is no need for the for loop.
All you have to do is:

var singleVal;

singleVal = array.reduce(function(acc, curr ){
  return acc + curr;
});
