Javascript Number() interface is returning wrong number

Issue

I'm using Number() to convert an input into number and it is returning the wrong number.

Couldn't find a reason for this:

const aux = Number("3721250857372431234");

console.log(aux)

it will print 3721250857372431400 instead of 3721250857372431234

Solution

Your number is bigger than the maximum safe integer and therefore the precision cannot be guaranteed.
