How do we convert scientific notation to number in Javascript

Question

So if I do 712569312664357328695151392 + 8100824045303269669937 I want the result to be:

712577413488402631964821329

But instead I have

7.125774134884027e+26

Answer 1

let a = 712569312664357328695151392;
let b = 8100824045303269669937;

(BigInt(a) + BigInt(b)).toString() will give you your expected result.
