BigInt

• JavaScript BigInt variables are used to store big integer values that are too big to be represented by a normal JavaScript Number.

• BigInt Decimals

  • A BigInt can not have decimals.

var x = 5n;
// var y = x / 2; // Error: Cannot mix BigInt and other types, use explicit conversion.

var y = Number(x) / 2;
console.log(y); //2.5

---

Create BigInt

• To create a BigInt, append n to the end of an integer or call BigInt().

var x = 9999999999999999n;
var y = BigInt(1234567890123456789012345);

console.log(typeof x); //bigint
console.log(typeof y); //bigint
