// Adding two big integers
const result1 = value1 + 1n;
console.log(result1); // "900719925124740999n"

const value2 = 900719925124740998n;

// Error! BitInt and number cannot be added
const result2 = value2 + 1; 
console.log(result2);

how to make a bigint in javascript

let bigInt = 1n;	// Using language construct
let bigInt2 = BigInt(1);	// Using function
