# JavaScript – If Else
##### Introduction:
In this article I am going to explain about the if-else statement in [JavaScript](https://www.mindstick.com/articles/874/how-to-create-watermark-text-for-textbox-by-using-javascript) and how we can use it.
When writing any program there are may arise situations when we have to take [decisions](https://www.mindstick.com/articles/12962/4-important-decisions-to-make-when-booking-your-cruise) at many places. We have to [choose one](https://www.mindstick.com/forum/159291/what-are-some-popular-alternatives-to-mern-stacks-and-when-you-should-choose-one-over-the-other) path out of two so, like other [languages](https://yourviews.mindstick.com/story/1463/some-oldest-languages-in-the-world-still-spoken) JavaScript provides us conditional statement i.e. if-else statement so that we can take decision in [programming](https://www.mindstick.com/articles/12214/web-development-company-in-india-laid-on-the-foundation-of-concrete-java-programming) with JavaScript.
##### JavaScript supports three types of if-else-statements:
1. If-statement.
2. If-else statement.
3. If..else if...statement.
[If statement](https://www.mindstick.com/forum/157628/what-is-meant-by-if-statement-in-python):
If statement is the fundamental control statement it allows JavaScript to make decisions and execute statements only when certain [condition](https://www.mindstick.com/forum/12711/select-query-with-and-condition) exists.
Syntax:
```
if(condition) { // code to be executed if condition is true}
```
##### Example of If-else statement:
```

```
##### If-else statement:
We will use [if else statement](https://www.mindstick.com/forum/55162/how-to-use-if-else-statement-in-java) to execute some code if certain condition is true and execute the other portion if condition is false. Here in either of the cases one block will execute.
##### Syntax:
```
if(condition) { // code to be executed if condition is true.}else{//code that will be executed if condition is not true.} If-else statement example
```
##### If-else-if statement:
This is one step more [advanced](https://www.mindstick.com/articles/12993/5-advanced-features-for-your-odoo-ecommerce-theme) form of conditional statement that allows JavaScript to make a [correct decision](https://answers.mindstick.com/qa/51365/why-did-the-fdr-choose-to-curb-military-funding-during-the-new-deal-do-you-think-this-was-the-correct-decision-at-the-time) out of several choices.
##### Example of if-else-if statement
```
If-else-if statement statement example
```
##### Conclusions:
Through this article we came to know about the if-else statement and how we can use it in Java Script to perform condition checking.
