I\'m not entirely sure why the string \"6145390195186705543\" is outputting 6145390195186705000, at first reading through the threads it may be the base radix but even tinkering around with that still gives me the same results, can anyone help explain because I do believe this is not a bug, but I\'m not entirely sure what\'s the explanation here.

  const digits = [6,1,4,5,3,9,0,1,9,5,1,8,6,7,0,5,5,4,3]
  const val1 = digits.join(\'\') // string \"6145390195186705543\"
  const test1 = Number(val1)  // outputs 6145390195186705000
  const test2 = parseInt(val1) // outputs 6145390195186705000

6145390195186705543 > Number.MAX_SAFE_INTEGER is true
