Sure. But in a sane language doing something totally nonsensical like that is an error, and in a statically typed language it’s a compiler error. It doesn’t just silently do weird shit.
Agreed! Unfortunately these maddening behaviors were kind of set in stone several decades ago, and it has been (correctly) decided “Don’t break the web”, these weird quirks are kept in modern interpreters/compilers.
It’s actually quite interesting to read through the logic to follow when implementing an interpreter:
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.

Pick one.
What’s a sane, dynamically typed language?

Lisp?
Any of them which are still strongly typed. Just because a language doesn’t check for type errors before runtime doesn’t mean it won’t check at all
