`abs()`

method?From mathematics, we know that the **absolute value** of a number is the distance from zero that a number is on the number line without considering its direction.

The `abs()`

**method** works the same way in JavaScript. It returns the absolute value of the parameter (number) that is passed into it.

Math.abs(parameter);

Note: The`Math`

object allows the use of mathematical functions. So, the`abs()`

method is called using this object.

**Parameter**

x

**Details**

Usually a number

The following is an example of the `abs()`

method with numbers:

/* educative.io abs() with numbers*/ console.log("The abs() method with Numbers \n"); console.log (Math.abs(5)); console.log (Math.abs(-5)); console.log (Math.abs(4*-5)); //same as |-20| console.log (Math.abs(5-8)); //same as |-3|

From the example above, we can see that the code outputs *positive* (absolute) values in all cases.

The following is an example of the `abs()`

method with other parameters:

/* educative.io abs() with other parameters*/ console.log("The abs() method with other parameters \n"); // when no(null) parameter is passed console.log (Math.abs(null)); console.log (Math.abs("")); console.log (Math.abs([])); // for lists and Strings console.log (Math.abs("Welcome to Edpresso!")); console.log (Math.abs([7, 5, 3, 1]));

In this example, the `return`

value for the `null`

parameter is **0**. The code outputs `Nan`

when a **string** or **list** is passed into it.
