Question 1

How to use ES6 features in old browsers?

Accepted Answer

Use the Babel transpiler as recommended in the FAQ. For Node.js, apply the require hook, and for browsers, combine Babel with Browserify and Babelify. Check the sibling project es6-support for pre-integrated examples.

Question 2

ES6-Features.org compared to other ES6 guides: which one should I use?

Accepted Answer

ES6-Features.org is best for quick syntax references and side-by-side comparisons, but for interactive learning or latest features, resources like Babel's Learn ES2015 or Axel Rauschmayer's books are more comprehensive. The site lists alternatives in its FAQ.

Question 3

What are the biggest advantages of ES6 over ES5?

Accepted Answer

ES6 offers cleaner syntax, reduces boilerplate code (e.g., arrow functions), and eliminates common hacks like using `var self = this`. It increases code expressiveness and is supported by modern transpilers, as explained in the FAQ.

Question 4

How do I switch coding styles on ES6-Features.org?

Accepted Answer

On the website, use the style toggle to switch between reduced (no semicolons) and traditional (with semicolons) styles. For bookmarking specific styles, append #reduced or #traditional to the URL, as detailed in the FAQ.

Question 5

Is ES6-Features.org still being updated?

Accepted Answer

The project was last updated around 2017 and focuses solely on ES6, so it doesn't cover newer JavaScript features. It's useful for learning ES6 basics but not for current developments like ES2020+ features.

Question 6

How can I contribute to ES6-Features.org?

Accepted Answer

Fork the GitHub repository, edit the `features.txt` file, and submit a pull request, as detailed in the FAQ section. Contributions are welcome for fixing mistakes or updating content.
