I manage amazing people here at Bloomberg. Sometimes I even write code. And when I do, I write it in TypeScript! Opinions are my own.

Extracted out from a talk I gave at work xitter.cf/acutmore/status/137478…
Gave my first internal talk at @TechAtBloomberg today. Comparing TypeScript, Flow and Hegel. Was really fun to do, and got to learn a lot putting it together.

A subtle aspect of type-assertions in @TypeScript I hadn't paid much attention to before: Direct assertions between literals are allowed even though they are not a super/sub type of each other. 📘
Rationale: github.com/microsoft/TypeScr…

My five most popular Effective #TypeScript posts of 2020: "Good use of generics or bad use of generics?" takes the top spot! effectivetypescript.com/2021…
You can use a type predicate such as :
function isValue(value : Value | undefined) : value is Value {
}
function main(value: Value | undefined) {
if (isValue(value))
return Object.keys(value).map(a=>a);
}

Also of course xitter.cf/awbjs/status/127149289… by @awbjs & me from HOPL-4 (2020).
HOPL proceedings includes the definitive copy of “JavaScript: The First 20 Years” by me and @BrendanEich. Differs from preprint in minor corrections and formatting changes—plus a bonus surprise. Preprint has been downloaded over 20000 times since March.
