#2They've just fixed what I regarded as the top reason for avoiding it completely: the broken type checking on functions.
It's a source of mystery that they didn't realise that was going to be a problem right from the start.

#4The string enums don't seem to work the same way as the number enums, there's no 2 way access.
For example.
enum Test { a } let a = Test.a; let b = Test[ 0 ]; // isn't available on the string ones
I wonder why its like that.

If you want a quick overview, then https://www.typescriptlang.org/docs/handbook/typescript-in-5....
If you want the full immersion, then read the entire Handbook: https://www.typescriptlang.org/docs/handbook/basic-types.htm....

For anything serious you are going to need to know JS, so yes, level up your JS first (up to ES5 is good enough) before switching to TS.

This language is getting better and better with each release

I learned JS through Eloquent JavaScript and did the various projects in the book, then changed all my .js files to .ts, turned on all of TypeScript's checks, and started adding types to my files.
I'd recommend doing a similar path; transitioning existing code to TS is IMO a better way to learn it than from scratch. TypeScript Deep Dive is a great resource.

Javascript the Good Parts by Crockford is a great book for people who already know a bit of JS but want to learn it proper and deeper.

#10Is Typescript goal to be the Java/C# of the browser/nodejs? static type checking, tooling and heavily OOP(as in Java/C#) based?
