📢I wrote a blog post on how @TechAtBloomberg uses TypeScript.

"10 Insights from Adopting TypeScript at Scale"

techatbloomberg.com/blog/10-insigh… A banana containing a blue stick of TypeScript dynamite. The
This is the first time we've really talked about our TypeScript infrastructure, despite it being used by over 300 internal projects. So there is a lot to unpack 🎁

Here's the OMGTLDR...
💡1. TypeScript can be JavaScript + Types

It's easy to take a JS purist approach & use TypeScript solely for erasable types. Use `target:ESNext` & avoid the TS features that affect the emitted JS runtime code.

This separation of concerns is no accident!

A very enjoyable & interactive evening at the London TypeScript Meetup @LndTypeScript organised by @wodlander.

Early doors shout to Optional Chaining landing in TypeScript 3.7 💥 Image
@dereknordgren shared his experience of championing the introduction of TypeScript @Hudl.

@mrbrentkelly explained the jump from Flow.

Sporty summary: "Just do it" Image
Finally @complexview visually demonstrated the power of TypeScript for accelerating art generation with some impressive live coding.

(There was a big audience out of shot, honest 😉)

Thanks to @HudlEngineering for hosting this fun evening. Image
