BigInt:

In JavaScript, we have a BigInt data type in which we can assign the integer of arbitrary length to an integer.

We can create BigInt by placing the n at the end of the integer or we can simply call the BigInt() function that creates an integer of arbitrary length from a string.


              
123456789

            
let bigint = 123456789n;
console.log(bigint);

let bigintFromString = BigInt("123456789");
let bigintFromInteger = BigInt(123456789);

console.log(bigint);
console.log(bigintFromString);
console.log(bigintFromInteger);
copy

Task

Create a BigInt() from the string “982945944” by using the BigInt() function and store it in the variable netWorth and display the value on the console.
