I love Typescript. It is very powerful and although it does have some disadvantages, once you start using it to its full capability it really speeds up development and decreases the potential for bugs to be introduced.
:any (this isn't good advice!). But doing this will not teach you how to best use Typescript.
Best Typescript books
I've only read one physical Typescript book - Effective TypeScript (link), published by O'Reilly. I would 100% recommend this book. It doesn't cover the basics, there is no introduction to Typescript - so only get this once you have played with Typescript enough to know the basics.
But when it comes to the best Typescript ebooks I've read quite a few. The ones that stand out and that I recommend reading are:
- Refactoring TypeScript by James Hickey link - again not a beginners guide but 100% worth getting.
- Essential TypeScript by Jess Chadwick (free) link- this is what I would recommend for absolute beginners
Typescript Deep Dive (free) link - A fantastic resource that every TypeScript developer should read through
Both of those are available on Leanpub.
Best resources to improve your typing abilities
The best way to get used to typing in Typescript is to practice. Two of the best resources I've found (which have challenges for you to do) are:
- Type challenges link - This is a Github repo which links to a Typescript playground (such as this), so you can work out how to complete the challenge and get it typed correctly. You can view the answers in the repo PRs too
- Typescript exercises link this is a slightly more structured collection of Typing challenges. There are currently 16 for you to do.
Using those two resources alone (once I knew the basics very well) were the only way that I started to really understand generics and how to correctly type things with use of the TypeScript keywords
How to keep up to date with the latest Typescript developments and releases
I keep up to date with Typescript via the fantastic newsletter TypeScript weekly. If you work with TS then you should be getting this in your inbox every week.
They have been running their newsletter for several years.
Another very important thing to be aware of is the Typescript release notes from Microsoft.
Every TS release (which comes quite frequently) adds many new features, and they always have very good documentation explaining the new feature (and why it was introduced). You can also follow them on Twitter @typescript
