I see the following in some code: if (xxx === undefined)
And I see the following in some other code: if (typeof xxx == “undefined”) or if (typeof xxx === “undefined”) Is one preferred over the other, style-wise? Is one more efficient than the other? — Darin _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev
