# The for loop in JavaScript
[Introduction](https://yourviews.mindstick.com/view/85450/mesopotamia-introduction-to-an-ancient-civilization):\
The [for loop](https://www.mindstick.com/forum/857/nested-for-loop-in-java-for-a-triangle) is very popular looping constructs and it is widely used also when we want [execute](https://www.mindstick.com/interview/49/how-can-i-execute-a-php-script-using-command-line) same block of code over and over again.
##### Syntax of For Loop
```
for (Initialization; condition; Iteration statement) { code to be executed //if the condition is true }
```
##### It has three parts:
1) [Initialization](https://www.mindstick.com/interview/608/what-is-the-difference-between-assignment-and-initialization) Statement
2) [Condition](https://www.mindstick.com/forum/12711/select-query-with-and-condition) Statement
3) Iteration Statement
In Initialization Statement we initialize our [counter](https://www.mindstick.com/interview/33859/how-to-create-pixel-counter-in-javascipt) [variable](https://www.mindstick.com/blog/11493/what-is-a-variable) for eg. i=0; The initialization statement is the first statement and it is executed before the code given inside the loop is executed.
Condition Statement or test statement specifies the test criteria for the body part to keep executing. Till the time the Test Statement is true loop will continue executing as soon as the condition becomes false the code which are written inside the loop [stops working](https://answers.mindstick.com/qa/50437/how-to-fix-messenger-that-keeps-crashing-or-stops-working-on-your-iphone-x-after-installing-a-new-ios-update).
Iteration Statement iterates or decrements the counter variable by a specific number for eg. (i++ or i--). Each time our loop executes it either increments it or decrements it as the [requirement](https://yourviews.mindstick.com/view/85169/becoming-an-influencer-requirement-of-skills-and-knowledge) arrises.
