  1. I couldn't be more of a beginner and you helped me pass my test in 20 mins to enroll. Mind you the first 15 minutes I was searching for videos until I found this one. Now that I see the precourse work I'll definitely be doing that 🤣

  2. Absolutely loved it. I was so frustrated last couple of days because of it… have no idea. Absolutely loved the example and how you explain…. keep doing that please, it's incredibly useful.

  3. I wrote this code before watching this video 🙂

    Maybe your code is better than mine

    function reverse(str) {
    var letters = [];
    for(var i = 0; i < str.length; i++) {
    letters.unshift(str[i]);
    }
    str = letters.join('');
    return str;
    }

    console.log(reverse('hello world'));

  4. Thanks your videos are so helpful, I just started taking web dev class in NYC, and I'm the kind of person who learns by seeing the solution, understanding the mechanics, then learning to do a variation later. I get stuck trying to come up with something from scratch.

  5. My personal best pick from all over YouTube to Learn Coding(HTML, CSS, Javascript.. and how to become Fullstack Developer).

  6. Hey Tanzine…!
    The methods do not work for a string with many words, however it works for string with one word. So how can you fix this issue?

    var name= "It has worked Okay"

    // Method 1
    function revStr(a){
    var reverseStr = "";
    for (i=a.length-1; i>=0; i–){
    reverseStr += a[i]
    }
    console.log(reverseStr); // yakO dekrow sah tI …. instead of tI sah dekrow yakO !
    };

    revStr(name);
    /*
    //Method 2;
    function reverseStr(b){
    let strArr = b.split("")
    let reArr = strArr.reverse();
    let revStr = reArr.join("");
    console.log(revStr);
    }

    reverseStr(name); */ //yakO dekrow sah tI …. instead of tI sah dekrow yakO !
