Webpack (Babel) - https://babel.dev/

I do appreciate your transparency, though I disagree with the sentiment that I’m arguing from a position of bad faith.

It’s a self-evident fact that the Babel team has not shown a moment of interest in lowering their role in the JavaScript ecosystem to anything short of kingmakers. Have a gander at their GitHub README and what do we see?[1]

- “Babel is a compiler for writing next generation JavaScript.” Indefinitely.

- Over a dozen sponsor logos. An embarrassment of riches.

- A literal audio recording of a song in praise of the project.

The Babel team has a well documented history of their priorities[2], emphasizing the need for a modular approach that has no exit strategy[3]. At best, we have a case of accidental entrenchment and long term dependence on the Babel brewing as early as 2017![4]

Compare this infinite circus to the humble but popular Normalize.css, which has the express purpose to stop existing.[5]

If the Babel team wants to raise some money, they can start by putting a plan together that would codify an exit strategy. It’s certainly more noble than their current plan of barnacling on to every NPM package…

The problem was I had used some new code, Javascript's replaceAll(), that is unsupported by older browsers. And, the setup I have to automatically fix such issues (called babel) is out of date. So, while this problem appears to be resolved there, I hadn't updated that in awhile.

babel-loader(v9.1.0): allows transpiling JavaScript files using Babel and webpack.

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.

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.

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.

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.

TypeScript helps you in many ways in the context of a JavaScript app. It makes it easier to consume interfaces of any type.

In this guide, we'll be extracting information from Amazon product pages using the power of TypeScript in combination with the Cheerio and Crawlee libraries. We'll explore how to retrieve and extract detailed product data such as titles, prices, image URLs, and more from Amazon's vast marketplace. We'll also discuss handling potential blocking issues that may arise during the scraping process.
