Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Typescript Runtime Validators and DX, a type-checking performance analysis of zod/superstruct/yup/typebox
What's prompted me to look at this is my tRPC+Zod editor experience at work has become unusable. 2-3 seconds to just get autocompletion options on a tRPC path, and then another 2-3 for the next path, repeat. When investigated using TypeScript's tracing tools the data entirely points back to my team's Zod DTOs. What I learned is that Zod's performance is okay at the start, but when you start using methods like .extend/.pick/.omit (and so on) the performance regresses in the order of a magnitude. Rather than making this into a "Zod considered bad" post, I wanted to investigate how the alternatives which can be integrated with tRPC fare, and see whether I can do better.

Ten Years of TypeScript
When you can write a busy beaver machine in the type system, LOC ceases to be a good indicator or how long something should take to typecheck, imo. If you're frustrated with your build, you should use the trace tools on the TS wiki[1] to track down what types are slow to check, so you can attribute the slowness to the appropriate library authors/yourself and decide for yourself if the speed/correctness tradeoff they've made is right for you.

How to upgrade TypeScript versions - what's your process regarding breaking changes?
So I want to update my (very large*) project from TypeScript 2.3.3 to the latest version, and I know that a breaking changes doc exists.

JSR Is Not Another Package Manager
Regular expressions are part of the language, so it's not so unreasonable that TypeScript should parse them and take their semantics into account. Indeed, TypeScript 5.5 will include [new support for syntax checking of regular expressions](https://github.com/microsoft/TypeScript/pull/55600), and presumably they'll eventually be able to solve the problem the GP highlighted on top of those foundations.

TypeScript Essentials: Distinguishing Types with Branding
Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented with implementations.[3]
I don't think it has any relation to runtime type checking at all. It's refinement types, [4] or newtypes[5] depending on the details and how you shape it.

Smart Contract Programming Languages: sCrypt vs. Solidity
Learning Curve and Developer Tooling sCrypt is an embedded Domain Specific Language (eDSL) based on TypeScript. It is strictly a subset of TypeScript, so all sCrypt code is valid TypeScript. TypeScript is chosen as the host language because it provides an easy, familiar language (JavaScript), but with type safety. There’s an abundance of learning materials available for TypeScript and thus sCrypt, including online tutorials, courses, documentation, and community support. This makes it relatively easy for beginners to start learning. It also has a vast ecosystem with numerous libraries and frameworks (e.g., React, Angular, Vue) that can simplify development and integration with Web2 applications.

Understanding the Difference Between Type and Interface in TypeScript
As a JavaScript or TypeScript developer, you might have come across the terms type and interface when working with complex data structures or defining custom types. While both serve similar purposes, they have distinct characteristics that influence when to use them. In this blog post, we'll delve into the differences between types and interfaces in TypeScript, providing examples to aid your understanding.
