== Search Text for Your Name tutorial 5/7 ==
Okay! Last loopy step: add another for loop, this time inside the body of your if statement (between the if's {}s).
This loop will make sure each character of your name gets pushed to the final array. The if statement says: "If we find the first letter of the name, start the second for loop!" This loop says: "I'm going to add characters to the array until I hit the length of the user's name." So if your name is 11 letters long, your loop should add 11 characters to hits if it ever sees the first letter of myName in text.
For your second for loop, keep the following in mind:
First, you'll want to set your second loop's iterator to start at the first one, so it picks up where that one left off. If your first loop starts with
for(var i = 0; // rest of loop setup
your second should be something like
for(var j = i; // rest of loop setup
Second, think hard about when your loop should stop. Check the Hint if you get stuck!
Finally, in the body of your loop, have your program use the .push() method of hits. Just like strings and arrays have a .length method, arrays have a .push() method that adds the thing between parentheses to the end of the array. For example,
newArray = [];
newArray.push('hello');
newArray[0];   // equals 'hello'
 
Solve:
 
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]);
            
        }
    }
} 
 
output: 8
