I was trying to make a point without starting a flamewar that was beside the point. Personally I’d never choose a dynamically typed language for a production system. That being said, Python and Ruby complain if you try to add an array, dict/hashmap, string, or number to another (of a different type) so they’re certainly more sane than JavaScript.
I seriously doubt that a dual-language platform is ever going to supplant Electron. Electron has the major advantage that the entire app is written in one language. And according to Stack Overflow’s 2023 developer survey, 66% of devs use JavaScript, 45% use Python, 43% use TypeScript, and 12% use Rust. More devs use Java, C#, C++, PHP, and C than Rust. So 2/3 of developers wouldn’t have to learn a new language to use Electron, and only a small fraction of the remainder knows Rust.
