[Pas2js] How to split a string using an array as separator?

[silvioprog]

Oops, I forgot to send a patch. ^^'

Could you apply this one in attachment? The String.prototype.split() (and
many other string functions) allows to pass as *separator*(*) the most
powerful feature also presente in JS: regular expressions. After applying
the patch, it allows:

uses JS, Web;

var
  S: string;
  A: TStringDynArray;
begin
  S := 's:foo.bar';
  A := TJSString(S).split(TJSRegexp.New('[:.]'));
  console.log(A);
end.

Result:

(3) ["s", "foo", "bar"]

The equivalent version in pure JS (notice the regex part as parameter):

var s = 's:foo.bar';
var a = s.split(/[:\.]/);
console.log(a);

Result:

(3) ["s", "foo", "bar"]

Thank you again!

(*) Snip from MDN
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/split>
:

*"... Separator*
*Specifies the string which denotes the points at which each split should
occur. The separator is treated as a string or as a regular expression."*
