ESLint VS Babel (Formerly 6to5)

Let's be honest - setting up tools for a new project can be a frustrating process. Especially when you want to jump straight to coding part. This is often the case with ESLint and Prettier, two popular tools in the JavaScript ecosystem that can sometimes interfere with each other when it comes to code formatting. Fortunately, there's a simple solution to this process, and it's called eslint-plugin-prettier.

Do you have the need to find and fix problems in your JavaScript? Then ESLint is for you. With over 120 million downloads each month, it's definitely one of the most popular projects out there. The latest version introduces a new configuration system, designed to simplify available configuration options. Old and deprecated rules have been removed, and a new configuration inspector has been added. Check out the blog for all the highlights, and a migration guide.

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.

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.

created 6 years ago to solve the specific problem of managing the Babel repo packages
