Given the text above, I want to push each word after "By" and before SPACE onto an array. The result must be something like this:

name[0] = "Greili"
name[1] = "ToneBob"
name[2] = "hela222"

Here's a quick split and reduce:

var arr = str.split("By ").reduce(function(acc, curr) {
  curr && acc.push(curr.split(" ")[0]); return acc;
}, []);

Result:

["Greili", "ToneBob", "hela222", "NovaSplitz"]

I see the word you want is always the second word, so that's an easier way of solving the problem. You could split the string on each space, and then you have an array of words, where the word at index 1 is the name you want. Then add each name to a new array. 

var words = "By Greili ...".split(" ");
var name = words[1]; // "Greili"
var namesArray = [];
namesArray.push(name);

You'd need to do that for each of your comment strings, in a loop.

Try using a regular expression:

var regex = /By ([^\s]+)\s/g;
var s = 'string to search goes here';
var names = [];
var result;
do {
    result = regex.exec(s);
    if (result) {
        names.push(result[1]);
    }
} while (result);
