What is code ? What is coding ? What can JS do ? How we communicate with computer, Writing instructions for a computer to follow, JS can create website, analyse data, animate shape and create applications.

Variables are very common in coding. They allow you to reference the same piece of information multiple times. In JavaScript variables can be defined using var then giving the variable a unique name. For example, var myVariable = 'my example'.

        
            var myExample;
            myExample = 'I created a variable';
            print(myExample);
            myExample = 'I changed the value';
            print(myExample);
          
        

1. Created an Array
2. Used Array Indexing

If statements allow you to run specific section of code when a test is true. The code inside the parentheses () is the test. If the test is true then the code inside the block {} runs. If the test is not true, the the code inside the block doesn't run.

          
            var aNumber = 5;
            if (aNumber === 5) {
                drawBox(blue);
            }
            if (aNumber === 4) {
                drawBox(red);
            }
          
        

1. Used Math Operators
2. Used a Logical Operators

Vestibulum vitae ligula hendrerit, laoreet lorem bibendum, viverra mauris. Integer eu massa ac neque lobortis rutrum vitae sit amet metus. Vestibulum tempor ultrices mauris eu rhoncus. Nullam vitae libero euismod, egestas nunc non, feugiat urna. Ut sagittis, felis sit amet lacinia sagittis, lorem purus viverra eros, et placerat nunc nunc id ex.

Morbi aliquam iaculis leo ac luctus. Curabitur tellus nibh, iaculis non congue ut, pulvinar non enim.

1. Use a for loop
2. Used a Classic For Loop
3. Used Nested for Loop

A loop repeats the section of code within curly brackets {}. In JavaScript, a for of loop goes through each element in an array or string repeating the code for each element.

          
            var groceries = [
              'apples',
              'yogurt',
              'toothpaste'
            ]
            for (var element of groceries) {
              print(element);
            }
          
        

USED A CLASSICAL FOR LOOP II

In Javascript, a classic for loop repeats the same code inside the block { } a specified number of times. It is defined in three parts. The first part happens before the for loop starts and defines a looping variable (var i = 0;). The second part is a test that determines if the loop should keep repeating (i < 10;). And the third part updates the looping variable each time the loop repeats (i = i + 1).

            
              print('The loop will go as long as i is less than 10');
              for (var i = 0; i < 10; i = i + 1) {
                  print(i);
              }
            
        

Sed arcu lectus, pellentesque at dapibus vel, luctus id purus. Donec bibendum bibendum elit, vitae consequat dolor scelerisque ut. Etiam cursus libero non libero egestas, eget tempor ex vehicula. Donec bibendum ipsum facilisis cursus venenatis. Sed accumsan, tortor in tincidunt feugiat, nibh enim efficitur quam, ac euismod ipsum augue ut augue. Nunc et dui sit amet metus pretium ultricies. Cras posuere tempus magna, ac vehicula lorem pretium ac. Vestibulum et tortor erat. Quisque tincidunt leo arcu, in accumsan justo porttitor a. Morbi eu dolor consectetur, varius nisi et, imperdiet ante. Pellentesque porta consequat pellentesque. Integer porttitor, enim a commodo molestie, urna arcu malesuada lorem, quis gravida turpis tortor quis tortor. Donec eget justo volutpat, fermentum enim in, maximus magna.
