  1. You should mention here that if you declare an array with const, you can change it by pushing values to that array. like so:
    const myArray = ['Alex', 'Car'];

    In that case the result will be: ['Alex', 'Car', 'Bike']

  2. Thank you for your tutorials!

    I have some problem , the browser can't execute my code right.
    When I type: console.log("The area is: " + pi + r + r);
    I receive: The area is: 3.14255

    But, when I type without string in the console, everithing is going well:
    console.log(pi + r + r);
    I receive: 13.142

    The browser I use is Chrome Canary. I repeated every step you showed me.

    the code:

    window.onload = function() {
    const pi = 3.142;

    function calcArea(r) {
    console.log("The area is: " + pi + r + r); // the problem is here, it gives 'pi' as output



    Please help
