How does a For loop work in JavaScript

For Loop

The for loop is frequently used, usually where the loop will be traversed a fixed number of times.

Syntax:

Nested For Loop

For loop inside for loop

Syntax:

While loop

The while loop keeps repeating an action until an associated condition returns false.

Syntax:

Nested While loop

While Loop inside While Loop

Do While Loop

The do while loop is similar to while loop, but the condition is checked after the loop body is executed. This ensures that the loop body is run at least once.

Syntax :

Nested Do While Loop

Do while inside Do while

Define What is Loop and what are the Types with Syntax.

In this tutorial iā€™m going to define what is loop and what are the types with syntax with examples.

What is Loop?

Any Repeated task more than one time that is called Loop. In a loop structure, the loop asks a question. If the answer requires action, it is executed. Using loops in computer programs simplifies rather optimizes the process of coding.

Types of Loops?

  1. While Loop.
  2. Do while Loop
  3. For Loop

While Loop:- While loop is a pre-test loop. It first test a specified conditional expression and as long as the condition true action taken. While loop also known as Entry Control Loop

Syntax with example:-

<?php

$am =1;

while($am<=6;
{
echo "this is while condition: $am <br />";
$am++;
}
?>

2. Do while Loop:- Do while loop is similar to while loop but the condition is checked after the loop. This ensure that the loop body is run at least once.

<?php

$ami = 3;

do{
echo "this is Laravel Amit: $ami <br />";
$ami++;

}while($ami<=6);

?>

3. For Loop :- The for is frequently used usullay where the loop will be traversed a fixed numbers of times. A loop variable is used to control the loop

Syntax + example:-

<?php

for($num=1; $num<=5; $num++)
{
echo "this is for loop: $num <br />";
}

?>
