loops

Loops are handy, if you want to run the same code over and over again, each time with a different value.

Different Kinds of Loops :

JavaScript supports different kinds of loops:

• for - loops through a block of code a number of times
• for/in - loops through the properties of an object
• for/of - loops through the values of an iterable object
• while - loops through a block of code while a specified condition is true
• do/while - also loops through a block of code while a specified condition is true

1. The For Loop

The for loop has the following syntax:

for (statement 1; statement 2; statement 3) { // code block to be executed }

• Statement 1 is executed (one time) before the execution of the code block.

• Statement 2 defines the condition for executing the code block.

• Statement 3 is executed (every time) after the code block has been executed.

2. While Loops

The while loop loops through a block of code as long as a specified condition is true.

Syntax while (condition) { // code block to be executed }
