JavaScript - get max supported integer value

In this article, we would like to show you how to get supported max integer value in JavaScript.

Quick solution:

JavaScript supports 53 bits integer numbers when we work on number type.

9007199254740991 (in dec)

11111111111111111111111111111111111111111111111111111 (in bin)

1FFFFFFFFFFFFF (in hex)

xxxxxxxxxx

const maxValue = Number.MAX_SAFE_INTEGER;  // 9007199254740991

In this example, we print in the console the Number.MAX_SAFE_INTEGER constant that represents the maximum safe integer in JavaScript.

xxxxxxxxxx

console.log(Number.MAX_SAFE_INTEGER);  // 9007199254740991

Output:

xxxxxxxxxx

9007199254740991
