javascript Your second "for" loop

Question

var text = "Hello world Keya how you doing Keya";

var myName ="Keya";
var hits = [];
for(var i=0; i<text.length; i++ )
{
if (text[i]=== 'K')
{
    for (var j=i; j< i+ myName.length; j++)
    {

          hits.push(text[j]);
    }
  }
}

I don't understand what is hits.push

secondly, I don't know

for (var j=i; j< i+ myName.length; j++)

You tried googling these things? Some search queries: `javascript push`, `javascript for loop`, `javascript arrays` — Wouter J, Jan 23 '16 at 11:42
So really what you're saying is that you don't understand javascript, and should get a book ? — adeneo, Jan 23 '16 at 11:42

for `push`, try Googling "MDN push". MDN is a great site which will answer many of these questions for you. For the `for` statement, you could google "MDN for". — , Jan 23 '16 at 14:46

This code for the myName variable which is in this case 'Keya' in the string text .

hits variable store the name as an array.

for(var i=0; i<text.length; i++ ) Run through the string
if (text[i]=== 'K') If text[i] is the first letter of your name (it would be more flexible if you change it to name[0])
for (var j=i; j< i+ myName.length; j++) Run through the string starting for from i (the index the first letter in the name found in text) to i+ the length of the name
hits.push(text [j]) Add text[j] to the array ( see JavaScript Array push() Method )

   var text = "vinod kumar";
    var myName = text;
    hits = []

    for(i=0; i < text.length; i++) {
        if(text[i] == "u") {
            for(var j=i; j < (myName.length+i); j++ ) {
                hits.push(text[j]);
            }
