I want:

you should accept and possibly vote up if it helped you – Chris Hawkes Mar 07 '16 at 18:25
Note that splitting twice is not necessary, using a variable to hold the result of split could be a step towards a DRY solution – axelduch Mar 07 '16 at 18:28

@axelduch yeah, that and make sure there are at least 2 strings to pick – juvian Mar 07 '16 at 18:33

You can use the window object for assigning global variables.

var str = "String1;String2";

str.split(';').forEach(function (a) {
    window[a] = a;
});

document.write(String1 + ' ' + String2);

Am I missing something here? OP didn't ask anything about global variables or the window object – sg.cc Mar 07 '16 at 18:28

@sg.cc Nina answered the constraint of having named variables available in the scope. But I suppose one could argue that it is an option not to name them at all in the first place. A compromise could be to underline the fact that it may have undesirable side effects. – axelduch Mar 07 '16 at 18:30
