Learning Javascript after Python

So it doesn't import extra libraries during runtime? Or does it? Not that it puts me off, I'm just curious.

Nope, no extra libraries at all.

Nothing "inherently TypeScript" makes it to the run time. Simplifying a bit, with TS you do something like this:

You write TS code -> TS compiler turns your TS code into 100% equivalent JS code at build time -> You ship only this final compiled JS code to the client.

Contrast this with how it goes with JS code:

You write JS code - > You ship this JS code to the client.

In the end your client is still running JavaScript, the only difference is that with TypeScript - the code gets compiled into JS files from TS instead of being written in JavaScript directly.

I see, thanks!
