Unlocking the Power of JavaScript: Understanding MAXSAFEINTEGER
When working with integers in JavaScript, it’s essential to know the limits of what’s possible. That’s where MAXSAFEINTEGER comes in – a crucial constant that ensures accurate representation and comparison of integers.
What is MAXSAFEINTEGER?
With a value of 2^53 – 1 (9007199254740991), MAXSAFEINTEGER 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 MAXSAFEINTEGER
To tap into this constant, you’ll need to use the Number class name. The syntax is straightforward: simply type Number.MAX_SAFE_INTEGER to access its value.
Example in Action
Take a look at the output when you log Number.MAX_SAFE_INTEGER to the console:
Output: 9007199254740991
Going Beyond MAXSAFEINTEGER
If you need to work with integers exceeding MAXSAFEINTEGER, 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.
