Update typescript from 3 to 4

[johann1301s]

TSDX uses typescript version 3.

Many new features are available in version 4. Please update to the latest version.

[tim-phillips]

The latest code in this repo uses typescript v4, but the latest published version of TSDX is still referencing v3, however the build step in the published version is using [email protected], which is using [email protected].

If you for example use Template Literal Types, for instance;

type World = "world";
 
type Greeting = `hello ${World}`;

Compilation fails since it is a TS 4.1 feature.

@tim-phillips That's not correct. At least with yarn. Rollup gets to use ts 3.9. I have a script that removes that typescript from local node_modules of tsdx. That makes it use ts 4 installed. Something like this:

"prebuild": "rm -rf node_modules/tsdx/node_modules/typescript"

There are a number of other issues in this repository about the super-old TypeScript 3.9.9 inside [email protected] causing problems for people, where this is documented:

I think this repo is abandoned by @jaredpalmer
