JavaScript reverse the order of letters for each word in a string

Question

I am trying to get around the following but no success:

var string = 'erehT era a tsav rebmun fo secruoser rof gninrael erom tpircsavaJ';

var x = string.split(' ');
for (i = 0; i <= x.length; i++) {
  var element = x[i];
}

element now represents each word inside the array. I now need to reverse not the order of the words but the order of each letter for each word.

Answer 1

var string = "erehT era a tsav rebmun fo secruoser rof gninrael erom tpircsavaJ";
// you can split, reverse, join " " first and then "" too
string.split("").reverse().join("").split(" ").reverse().join(" ")

Output: "There are a vast number of resources for learning more Javascript"
