As the name says, the increment operator increases the value of a variable by **1**. There are two types of increment operators: `pre-increment` and `post-increment`. |
|
|
|
## Pre-increment |
|
|
|
The pre-increment operator increases the value of a variable by 1 and then returns the value. For example: |
|
|
|
```js |
|
let x = 1; |
|
console.log(++x); // 2 |
|
console.log(x); // 2 |
|
``` |
|
|
|
## Post-increment |
|
|
|
The post-increment operator returns the value of a variable and then increases the value by 1. For example: |
|
|
|
```js |
|
let x = 1; |
|
console.log(x++); // 1 |
|
console.log(x); // 2 |
|
```
