Another good alternative is Facebook's flow. Rather than being a transpired language it works on top of JavaScript files.
This two tools are amazing and it improves working with JavaScript to the point of never wanting to go back to not typed JavaScript
- Tx3 10y agoYou're absolutely right. Flow seems to be a very good alternative. One thing I would like to add regarding the .js files, TypeScript 1.8 added a flag --allowJs which makes some sanity checks to the plain old .js files.
- lobster_johnson 10y agoIt sounds like --allowJs alleviates the need to create TypeScript definitions for everything? So if you have an existing project based entirely on JavaScript, you can gradually convert each file to .ts without having to do anything else?
- nojvek 10y agoThat is true. You slowly add more black typescript to a white js project as you go along and decide the shade of grey you want.
- danielearwicker 10y agoDefinitely an aim of TS to make it easier to continue using JS for those who prefer a half-way house, see: https://github.com/Microsoft/TypeScript/issues/4789 https://github.com/Microsoft/TypeScript/issues/4789
- hiphipjorge 10y agoWell, you still need some transpiling in order to remove the Flow type signatures. In practice, they end up being pretty similar in terms of needing a build step.
- TAForObvReasons 10y agoYou can embed the type information in special JS comments that the checker understands: http://flowtype.org/blog/2015/02/20/Flow-Comments.html http://flowtype.org/blog/2015/02/20/Flow-Comments.html Your existing minification step will remove the comments. But even if you don't remove the comments the code will still run.
