Unlocking the Power of JavaScript: Understanding MAX_SAFE_INTEGER

What is MAX_SAFE_INTEGER?

When working with integers in JavaScript, it’s essential to know the limits of what’s possible. That’s where MAX_SAFE_INTEGER comes in – a crucial constant that ensures accurate representation and comparison of integers. With a value of 2^53 – 1 (9007199254740991), MAX_SAFE_INTEGER is a non-writable, non-enumerable, and non-configurable property. The term “safe” refers to JavaScript’s ability to precisely represent and compare integers within this range.

Accessing MAX_SAFE_INTEGER

To tap into this constant, you’ll need to use the Number class name. The syntax is straightforward:

console.log(Number.MAX_SAFE_INTEGER);

This will output:

9007199254740991

Going Beyond MAX_SAFE_INTEGER

If you need to work with integers exceeding MAX_SAFE_INTEGER, don’t worry! JavaScript has got you covered with BigInt. This data type allows you to represent larger integers, giving you more flexibility in your coding endeavors.
