JavaScript .MAX_VALUE

JavaScript’s .MAX_VALUE represents the largest positive numeric value that can be represented using the Number type before it overflows to Infinity.

Syntax

Number.MAX_VALUE;

Parameters:

None: .MAX_VALUE is a static property of the Number object.

Return value:

A number representing the largest positive finite value JavaScript can represent using the Number type (approximately 1.7976931348623157e+308).

Example

This example shows what happens when a number exceeds .MAX_VALUE:

const large = Number.MAX_VALUE * 2;
console.log(large);

Multiplying beyond .MAX_VALUE causes the result to overflow to Infinity, since JavaScript can’t represent values larger than this limit.
