You can work around this by typing your import statement inside-out: import {} from 'fs'; Then move your cursor back inside the {} and you'll have nice autocomplete. Works with object destructuring, too.

What about Object.fromEntries? See https://github.com/tc39/proposal-array-grouping for why this isn’t a method on Array.prototype.

Thanks for the correction, Paul (and for the great email client and JS Compiler!). I've added a note to the article. The focus on inlining as a performance win makes a lot of sense. It's hard to get back into the pre-JIT IE6 minds

Beyond that the branding is also confusing. Is it Closure? The Closure Compiler? Closure Tools? Google Closure? I used it for years and I'm still not clear which is right.

That is an interesting note (and news to me as the article author). Note that they used Closure in its "simple" mode, rather than "advanced", which is what the post is mainly talking about. I wonder if React still uses C

The lack of RTTI in TypeScript _is_ definitely a pain but the jump to "must use decorators" and "TypeScript is not a server language" is unjustified. There are many approaches to validation and RTTI with TS. For example,

This is fascinating. It reminds me of the infamous MCAS on the Boeing 737 MAX. A system was designed, implemented and rigorously tested to be used in a specific scenario. A decision was then made much later to use it in a very different sce

I'm curious about the results, but remember that this article is talking about the type declarations files that tsc has to read (.d.ts files), not the JS that winds up in your bundle.

Yes, the underlying issue has been resolved and so this should be a relatively easy fix for any project using `googleapis`. It's not mentioned in the article, but we also added an eslint rule to ban importing `googleapis` so that this

This is the size of the type declarations files (.d.ts files) that `tsc` pulls in when compiling your code. This is distinct from bundle size. Tree shaking is a big win for bundle size. One of my big takeaways from looking at these visualiz

My understanding is that skipLibCheck skips _type checking_ .d.ts files, i.e. looking for type errors in them. But tsc still has to read those files since you might refer to their types in your own code, which TypeScript will type check.

By default, Node has a relatively low limit on the amount of memory it will use (I believe 1GB). As you get close to this, it thrashes as it tries to garbage collect more and more frequently. You can increase the limit by running `node --ma

Why is it so important to express this as one SQL query? Why not just run the two simple queries? It feels as though two different types of things are being joined.

If you prefer the "or throw" approach to handling null values, you can write a little helper to get something like it in TypeScript: function assert<T>(v: T | null | undefined, message?: string): asserts v is T {

I've run into many more performance issues with editor latency (i.e. tsserver) than with compiling (tsc). Unfortunately, these tend to be harder to diagnose. The worst turned out to be a crashing bug in tsserver that manifested as auto
