I am trying to convert the following big int to a string in javascript with no success. My goal would end up with '582235852866076672'

var foo = 582235852866076672;

console.log(foo); // 582235852866076700



var baz = ' + 582235852866076672 + ';

console.log(baz); // '582235852866076700'



var emptyString = 582235852866076672+'';

console.log(emptyString); // 582235852866076700



var n = foo.toString();

console.log(n); // 582235852866076700

I figured the number was too big and was loosing precision as a result.
I included the bigint library with no success:

var bigint = require('bigint');

var bigintLibrary = bigint(582235852866076672).toString();

console.log(bigintLibrary); //582235852866076700

The method toSting in the bigint library states:

Print out the bigint instance in the requested base as a string.

I appreciate all help and comments. Thanks.
