The trouble with Mozilla's docs is that they are really bad about distinguishing between cross-browser compatible JavaScript and Mozilla's own implementation. For example, the reference you linked there includes the let-statement. The only disclaimer in Mozilla's docs is that it's part of "JavaScript 1.7," which would lead you to believe it's part of a recent language standard that modern browsers are likely to support. In fact, "JavaScript 1.X" where X > 5 is code for "Firefox-only." |
