JavaScript Number.MAX_VALUE Property

Number.MAX_VALUE represents the biggest possible numeric value of a positive number that can be represented in JavaScript. It is the maximum possible positive number representable in JavaScript within float precision.

Syntax:

Number.MAX_VALUE

Return Value: It possesses the value of the biggest positive number which is approximately 1.79E+308, or 1.7976931348623157 * (10^308).

Note: As MAX_VALUE is a static property of the Number class, we should always use it as Number.MAX_VALUE instead of using as a property of the object created from the Number class ( static properties always belong to the class, not to the objects). So, we create a Number object and try to access the MAX_VALUE property of the object, it will return undefined.

If we take the negative of Number.MAX_VALUE, it will represent the minimum possible negative number in JavaScript as the value of the negative number will be maximum making it minimum possible negative number.

Example 1: 

HTML

<script type="text/javascript">
    let num=100;
    console.log(num.MAX_VALUE);
    console.log(Number.MAX_VALUE);
</script>

Output:

undefined

Example 2:
