# How to Returns the absolute value of x in JavaScript ?

In JavaScript, we can return the absolute value of a number using the `Math.abs()`

method. This method returns the absolute value of a number, which is the positive value of the number, regardless of its sign.

Here's an example:

```
let x = -5;
let absX = Math.abs(x);
console.log(absX); // Output: 5
```

In this example, we first declare a variable `x`

and assign it a value of `-5`

. We then use the `Math.abs()`

method to get the absolute value of `x`

and assign it to a new variable `absX`

. Finally, we log the value of `absX`

to the console, which outputs `5`

.

Another way to get the absolute value of a number in JavaScript is by using a conditional statement. We can check if the number is negative and multiply it by `-1`

to get its positive value. If the number is already positive, we can simply return the number.

Here's an example:

```
function getAbsoluteValue(x) {
if (x < 0) {
return -x;
} else {
return x;
}
}
let absX = getAbsoluteValue(-5);
console.log(absX); // Output: 5
```

In this example, we define a function `getAbsoluteValue`

that takes a number `x`

as its parameter. We then use a conditional statement to check if `x`

is negative. If it is, we return `-x`

to get its positive value. If `x`

is already positive, we simply return `x`

. We then call the `getAbsoluteValue`

function with a value of `-5`

and assign its return value to a variable `absX`

. Finally, we log the value of `absX`

to the console, which outputs `5`

.
