You can find the absolute value of a number in JavaScript by using the `Math.abs()`

method. The absolute value of a number means how far a number is from zero.

`Math.abs()`

only takes one `number`

type parameter and return the absolute value of that number:

```
Math.abs(-5);
Math.abs(5);
// both returns 5
```

Both the negative number `-5`

and the positive number `5`

is `5`

numbers away from zero (so both returns `5`

)

When you pass more than one parameter, JavaScript will ignore the rest and operate only on the first:

```
Math.abs(-3, 5);
Math.abs(-3, "Hello");
// returns 3
```

When you pass non-number data type, the method will return `NaN`

as value:

```
Math.abs("String");
// returns NaN
```
