In this article, you will learn how to **convert a positive number into a negative number in Javascript**.

Let’s say you have a number variable called ‘a’ with value 123.

`var a = 123;`

In order to convert a positive number into a negative number, you can use the unary negation operator `-`

.

```
var a = 123;
console.log(-a);
```

**Note: **The unary negation operator `-`

functions by converting any value on its right side into a number and negates it.
