Object('abc') is the same as new String('abc'), Object(1) the same as new Number(1) - it just calls the .constructor


but "new Number(x)" is not equal to "Number(x)". So, it's tricky, I guess?


Number(x) performs a type conversion to number, new Number(x) constructs a primitive wrapper object Number:

  typeof Number("10")
  //=> "number"
  typeof new Number("10")
  //=> "object"
The same applies to other wrapper objects, that is, Boolean and String.
