Loops

In this paragraph, we will learn something interesting called loop.

Consider that you need to print a line 100 times using JavaScript. What you will do?

You can type document.write("The line I want You to Write"); 100 times in your program or you can use loop.

The basic use of loop is to do something more than one time. Say, you need to print all the integers of 1 + 2 + 4 + 6 +…………+100 series upto 100. The calculation is the same, you only need to do it multiple times. In these cases, we use loop.

We will discuss two types of loops, namely for loop and while loop.

for(starting ; condition ; increment/decrement)

The starting parameter is the initialization of your loop. ...
