We follow the standard JavaScript style, except for semicolons and trailing commas.

Additionally, we enforce a pretty strong functional programming style with ESLint, which includes:

• no complex/big functions/files
• no object-oriented programming
• immutability everywhere
• pure functions
• no complex loops nor structures

Also we prefer:

• named arguments over positional
• async/await over raw promises or callbacks
• destructuring
• ...object over Object.assign()

Tooling

We are using editorconfig, so please install the plugin for your IDE.
