But JavaScript just does not need to do that.
Let's get back to the problems with JS functions: 1. Overlong syntax, mainly due to 'function' and 'return' keywords, but also due to lack of expression body alternative or combination. 2. Dynamic 'this' parameter binding. 3. Tennent's principle of abstraction violations other than 'this'. Arrow function syntax addresses 1 and (via =>) 2. Block lambda revival addresses all three. I think both are worth considering carefully, never mind fashion, for these reasons. /be _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
