Basic Guide to JavaScript Loops

Whether you are working with JavaScript or any other language, repeating the actions is one of the most common tasks in the programming. Repetition of actions is like running the same code multiple times.

And this task can be done using Loops.

Instead of writing same code again and again, you can write in short using loops.

So, let’s check it out how to do it.

In JavaScript, there are mainly 5 types of loops:

•  for 
• for/in 
• for/of 
• while 
• do/while 

Let’s talk about them one by one.

Definition of “for”: It executes through the block of code.

Definition of “for/in”: It executes through the properties of an object.

Definition of “for/of”: It executes through the values of an iterable object.

Definition of “while”: It executes through the block of code when a condition is true.

Definition of “do/while”: It executes through the block of code only one time, after this it repeats the action when the condition is true.
