There isn't much of a difference between regular enum and const enum when it comes to the usage of the enum keyword. The big difference is what they compile to - where const enum evaporates by inlining the values into the usage sites.

Whilst TS does technically contain breaks, these are normally simple increases in the power of the type-checking. It's finding more errors in code that previous seemed fine. Think of it like adding more ESlint rules. It's rare f

What about VS Code?

That's an excellent suggestion! It's true you could just have every package publish the raw TypeScript source-code. So that when an app imports a library, it type-checks against the original source code of the library. No need f

It's more about setting up the guard-rails ahead-of-time to avoid falling into a hole, rather than getting out of one. We know the way to do this is to stick to standards like ECMAScript. ES Modules are the glue that binds the whole J

The TypeScript ecosystem is amazing - partly because of the large number of users also also because of the sense of community. It is run as a true OSS project. Roadmaps are release plans are all public on GitHub. Even as outsiders we&#x2

Agreed. The article touches on this. When you have hundreds of projects that all target the same tightly-managed evergreen runtime, there's not much justification for having each project select and maintain a different toolchain. It

Yes - you deduced correctly! There was a long period of parallel evolution. Over the last few years we've been able to get back on the standards track. The article describes this as one of the guiding principles. It's why we pa

What other numeric types would you like to see? In addition to the existing doubles, ES2020 added support for signed integers.

That book is one of the most useful engineering books I have ever read. Top quality theory with practical application.

Rollup's strength is its simplicity and focus. It splits a fine-grained module graph into coarse-grained vanilla ES modules with zero duplication across fragments and no artificial overheads, e.g. no wrapping internal modules inside fu

I met Art, the Sencha CEO, back in 2013 after having some positive experiences using Sencha Touch on iOS to develop consumer-facing apps. He said that the company was going to solely focus on Enterprise because that's what the investor

Agreed. ES6 class syntax is superior to constructor functions and prototype mutation, because it's declarative and statically analysable. I think the only legitimate reason left not to use ES6 class syntax is (for perf sensitive code)

A codebase with no objects... I am guessing you mean no classes.

So the argument is that the bad-effects of top-level await are viral. One bad apple in the app entry point's dependency graph stalls evaluation of the main entry point. And to mitigate this risk, you have to segregate out sub-graphs
