Introduction
Have you ever encountered situations where standard JavaScript numerical primitives couldn’t hold vast integer values? Fear not! Starting from ES2020, we now have access to a fantastic feature called BigInt
. It enables us to seamlessly manage immeasurable integers while performing arithmetic operations without losing precision.
In this comprehensive tutorial, I’ll walk you through everything you need to know about utilizing BigInt
, including its creation process, fundamental functionalities, and limitations.
Getting Started with BigInt
To begin, there are two ways to define a BigInt
value:
- Append the letter ’n’ after any decimal integer:

console.log(`Value: ${billion}`); // Value: 1000000000
2) Call the global BigInt()
constructor, passing a string representation or another numeric type as an argument:
let sameBillion = BigInt("1000000000");
console.log(`Value: ${sameBillion}`); //…
