![]() Making one change can affect the behavior of multiple files. Those kinds of applications contain hundreds of different files. ![]() TypeScript was created to address problems coming with developing large-scale applications in JavaScript. It’s a superset of JavaScript: any JavaScript code runs in a TypeScript environment. with buggy browser impementations), etc.TypeScript is an open-source programming language developed and maintained by Microsoft. Note that much of JS's bad rep (beyond the acknowledge "bad parts that can't be removed" -) comes from stuff that doesn't really "belong" to JS as a language: buggy implementations, the mess that the HTML DOM can often be (esp. Probably one of these days a fast server-side implementation (probably with "use strict " or the like enforced, once that's officially blessed -) will start gaining a substantial foothold, just because so many web programmers already have some JS knowledge (they have to, to make good web apps). ![]() ) and tools (Firefox has maybe the best add-ons for JS tracing and debugging, but other browsers are rushing in that direction too), JS has become usable in recent years. by Crockfor's "lint" program for JS) and a good supporting framework (jQuery, Dojo, Closure. With strict self-imposed programming discipline (enforced e.g. JS is by far the most widely deployed language in the world (those billions of browsers.), huge investments are made in it by many companies and open source groups in competing implementations and supporting frameworks (Python's no slouch at that either, but the difference is still there), practical improvements (speed, warnings) keep piling up on JS's side as a consequence (even though the language proper can't improve). Python is deployed in more traditional ways, so gradual language changes have enhanced it over the years (it was also designed with less hurry, and ] ended up with a better design from the start, in many respects).Īs a result, Javascript (so far) has not enjoyed much success "server side", where programmers get a choice (even though they still have to use JS for "browser side" code). This might change if something like a use strict directive ever makes its way into ECMAscript (though programming in ways that support old, and often buggy, browsers, will still be like pulling teeth - like writing Python code that runs unchanged all the way from Python 1.0 to 3.1 would be!-). (See Crockford's Javascript: the good parts for a reasonable discussion by a JS expert and enthusiast about the good and bad parts thereof). The key fact is that Javascript is very hard to ever change (because of billions of old implementations existing in browsers), so design errors made in early (and frantically hurried -) stages are still with the language today. Nowadays, however, it also becomes popular in server-side and desktop applications as Node.js. Javascript used to be solely used for building interactivity on web pages. Python is a general scripting language, which can sometimes be used to do server-side work. That's why language modifications like CoffeeScript, Typescript and Dart have emerged.Īs noted by spinon, these programming languages were used in very different ways. But once you start making anything big, it becomes hard to keep track of. It's easy enough to learn, and is good for small scripts which is what is was designed for. Javascript is the bane of many a programmer's existences. You can also build up from programming basics, starting by learning functions and then moving into classes. Since it's a scripting language, you can easily try stuff out and immediately see the results. It's associated with a large, active, and friendly community. If you're just learning a language, then there is none better than Python.
