ESLint VS TypeScript-Website

ESLint: A pluggable and configurable linter tool for identifying and reporting on patterns in JavaScript.

Automating code checks with static code analysis allows us to enforce code styling effectively. By integrating tools into our workflow, we can identify errors at an early stage, while coding instead of blocking us at the end. For instance, flake8 checks Python code for style and errors, eslint performs similar checks for JavaScript, and prettier automatically formats code to maintain consistency.

If you're a developer, you're surely familiar with Prettier and ESLint. With over 8 years of existence, they have established themselves as references in the JavaScript ecosystem.

eslint is used to avoid code errors

No lint errors: The committed code does not contain any lint errors (eslint).

Let’s walk through the steps for a one-time setup to configure husky pre-commit and pre-push hooks, ESLint with code styles conventions, prettier code formatter, and lint-staged. Husky automatically runs a script on each commit or push. This is useful for linting files to enforce code styles that keeps the entire code base following conventions.

1. Lack of Static Code Analysis Static code analysis tools like TypeScript and ESLint play a crucial role in identifying and preventing bugs. TypeScript provides static typing, enhancing the robustness of the code. ESLint detects issues and enforces coding standards. The absence of these tools can significantly elevate the likelihood of bugs due to the lack of early detection and guidance provided during development.

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.
