How to run loops?

Rating:

Loops are a set of statements that run a statement or a set of statements several times until the given condition is true. If the condition becomes false, the execution of the loop stops and the control is passed on to the next statement.

There are three kinds of loops in JavaScript, which are as follows:

1. The for loop: The syntax of the for loop is as follows:


for(initialization;condition;increment/decrement)
{
       //statements
}

The following is an example of running the for loop:

for(x=0;x<10;x++)
{
       document.write(x)
}


2. The while loop: The syntax of the while loop is as follows:


while(condition)
{
       //statements
}

The following is an example of running the while loop:

while(x<10)
{
       document.write(x)
       x++
}


3. The do-while loop: The syntax of the do-while loop is as follows:


do
{
       //statements
}while(condition)

The following is an example of running the do-while loop:

do
{
       document.write(x)
       x++
}while(x<10)
