dotJS 2012 - Brian Leroux - WTFJS

That's JavaScript for you. Here's a talk about the (in)sanity of JS: ▶ this video The same under Clojure (on top of the JVM) shall throw a class cast exception.

I don’t see why you are offended. I love JS but here it is 20min of programming jokes in the expense of JS: ▶ this video As it comes to PHP, I don’t say that you can do everything by a single PHP file in a web server folder(actually, you can but not comfortably). I’m trying to illustrate it’s low-code nature. There are no other languages that are that easy to start solving your problem with. Okay, maybe Python. The newer no-code or low-code tools have the same spirit. They are abstraction layers targeting a domain. These days there’s plenty you can do by programming visually without any knowledge of programming languages. Not everything needs to scale for throughput.

Meh. They're different languages with different expectations. "is" is distinct from "==" in both, and Python gets "==" right (obviously). Javascript doesn't really have any high ground here[0]. (In contrast, Python:) >>> [] == False False >>> object() == False False >>> "" == False False >>> {} == False False They're just different. [0]: ▶ this video

> No, actually, it doesn't. Perhaps less in what features to avoid, but there's plenty of hidden gotchas to avoid in JavaScript still. ▶ this video link > C++ is a huge language, javascript is a relativly small one. C++'s ISO/IEC 14882:2003 weighs in at 786 pages, compared to ECMA-262 (5.1 Edition)'s 258 pages (measuring by PDF reader). A ~3x difference, but not quite the order of magnitude I'd expect from huge vs small.

I'm glad that someone posted this :) See also a longer spin of of this talk at the more decent dotJS conference: ▶ this video
