@babel/plugin-syntax-bigint

What is @babel/plugin-syntax-bigint?

The @babel/plugin-syntax-bigint package allows Babel to parse code that contains the BigInt syntax. BigInt is a built-in object in JavaScript that provides a way to represent whole numbers larger than 2^53 - 1, which is the largest number JavaScript can reliably represent with the Number primitive. This plugin does not transform BigInt syntax, it only enables the parsing of it.

const bigIntValue = 123n;
