# JavaScript | Math.SQRT2 property

The Math.SQRT2 is a property in JavaScript which is simply used to find the value of square root of 2, whose value is approximately 1.4142.
That is, √ 2  = 1.4142
Difference between property and function in javascript.
Property in JavaScript is nothing but a value whereas method is a function this can be understood anith the help of a example given below.

 `  `

Output:

```Audi
A8

sayModel is a method i.e, a function of the object and it can be accessed with car.sayModel().
It can be noticed that sayModel is just a function which use ().

Syntax:

`Math.SQRT2;`

Parameters: Here nothing is passed as a parameter because, Math.SQRT2 is not a function but it is a property.

Return Values: It simply returns the value of the value of square root of 2, whose value is approximate 1.4142.

Example:

```Input : Math.SQRT2
Output: 1.4142135623730951```

Explanation:
Here simply value of the square root of 2 is shown as output.

Let’s see JavaScript code for Math.SQRT1_2 property:

• Example 1:

 ` `

Output:

`1.4142135623730951`
• Example 2: Value of square root of 2 can be printed as in the form of function as shown below.

 ` `

Output:

`1.4142135623730951`
• Errors and Exceptions: Here we consider Math.SQRT2 as a function but in actual it is a property that is why error as output is being shown.

• Example:

 ` `

Output:

`Error: Math.SQRT2 is not a function`

Application: It’s application is to find the value of the square root of 2 which is done with the help of this property. In mathematics, it needed a lot.
Let’s see JavaScript program on this application:

• Example:

 ` `

Output:

`1.4142135623730951`
