I've been using CS for the past year or two, but I'm hearing a lot of buzz around TS for the past few months. It would be really nice to have a better idea as to why it should be best to move now - is it really that much better?
(I love the CS tools available on PyCharm; they really made my life easier. That said, I think that there are similar TS tools available as well)
CoffeeScript will always be something quite different. I love it, but that difference makes me nervous. ES6 ought to bring a lot of the features I like about CoffeeScript into JavaScript.
The TypeScript language team has yet to prove that they will track the specs and implement features as spec'd. I think claiming that they will "implement ES6 features" is a bit pre-mature. So far, they have implemented a few drafts and ignored a few others. A mixed bag.
Typescript main feature is tooling but I would rather go with lang where I'm not second class citizen on non-windows (eg. Dart's editor works on Windows/OSX/Linux)
- Typescript is a superset of Javascript (mostly), so we ported by converting all the Coffeescript sources to Javascript and renaming them with .ts extensions. There was a bit of cleanup involved in getting modules to play nice together, but most of the code ran without modification.
- The JS that the Typescript compiler generates is much easier to read, in part due to less "magic" in the language.
- It also makes performance much easier to reason about, for the same reasons. One issue that bit us several times was Coffeescript's auto-return feature, which was invisibly accumulating large arrays of values from our interpreter's bytecode loop! This is no longer a concern with the current Typescript codebase.
- The inner workings of the JVM are fairly complex, so enforcing types at compile-time actually does catch bugs before they happen.
Is just your regular js, but with some stuff added like type
check, classes, interfaces and some cute operators, just the
language that most know with some goodies added to help
with development, that is and that all, in oppose to CS that
is just syntatic sugar with others cute tricks that make the
language more appealing to people like you (assuming by your
post that you are a python developer). So if you are into JS
or type check then you should give TS a try, if not then
just stick with CS, only you can answer is changing
transpiler in your workflow is gonna make your life easier.
