antlr4ts VS TypeScript-Website

What about the drawing/programming language itself? Even though it's quite simple, we still need a tokenizer and an interpreter. We've chosen ANTLR to define the grammar, with antlr4ts as the target. That is, when running the ANTLR tool, the input is a file containing the grammar definition, and as the output, we get TypeScript files that handle the parsing of arbitrary text into an AST (Abstract Syntax Tree).

For new components, it does make sense to follow the style defined in the React documentation by writing components using a function definition. However, arrow functions using React.FC also remain a popular choice and are used by Vercel and the official TypeScript website

I opened a pull request to remove that, because you're right, there's no way somebody can read the whole handbook in 30 minutes!

Yep, this is my answer too - I use this pattern pretty often. For example, here's the main object that represents the TypeScript Playground at runtime: https://github.com/microsoft/TypeScript-website/blob/86901a0520855050b16b0c23bd6923212fdd0c9c/packages/playground/src/index.ts#L622-L623

In this series of articles, I intend to provide a detailed, accurate, and step-by-step explanation of how to implement a RESTful web interface using a stack of Typescript, Node.js, Dynamoose, DynamoDB, Jest, Serverless Framework, AWS, and Amazon Cognito.

Install TypeScript package: npm i -D typescript

Beyond testing your code, it's an excellent idea to write your library in TypeScript. Type errors are among the most common type of mistake in JavaScript, so using TypeScript will almost always reduce development time and may occasionally prevent you from publishing broken code if you forget to add a test. Moreover, the excellent TypeScript compiler will allow you to avoid using a bundler when publishing your package (we'll get into this more later) and will make supporting TypeScript and JavaScript users simultaneously much easier.

TypeScript is a JavaScript superset with optional type annotations checked during transpilation.
