How do you find duplicated values in an array?

var arr = ['manager','manager','employee','manager',
           'director','employee','manager','operatives'];

Im looking to get the values that were duplicated to return in an array, in this case manager and employee, so the return value will be ['manager','employee'].

Does it need to work for strings only, or for all types of values? – Šime Vidas Oct 21 '11 at 11:16

@pimvdb, @\manraj82: that solution needs a shim to work in IE 8 and lower. – Andy E Oct 21 '11 at 11:23
