This one enforces Spatie's JavaScript and TypeScript conventions, which are opinionated but sensible if you like wider lines and more spacing than typical JS defaults. It pushes for 4-space indents and 120-character line widths in Prettier, strict equality checks everywhere, const over let, and full variable names in multi-line functions. The destructuring and arrow function guidance is straightforward: use them when they make code clearer, skip them when they don't. If you're working on a Spatie project or just prefer their house style to Airbnb or Standard, this keeps everything aligned without thinking about it.
