I came across this JavaScript code snippet:
```javascript
console.log([] + []);
console.log([] + {});
console.log({} + []);
```
I'm curious about the output of each line and why they differ from one another. Any insights? 🤔

The differences come from how JavaScript automatically converts types. It tries to make sense of operations like `[] + {}` instead of throwing an error. In more strict languages, such nonsense would just cause an error. Crazy, right?
Thanks for clarifying! It really makes you appreciate more strict languages.
JavaScript can be pretty wild with its type coercion! Just remember, you can avoid these weird cases by not running this kind of code in production.
Seriously, what is up with JavaScript's rules? It's like it has a mind of its own!
