Both are totally unrelated programming languages and no relation between them. Java is statically typed, compiled, runs on its own VM. Whereas Javascript is dynamically typed, interpreted, and runs in a browser and nodejs environments. Let's see the major differences in a tabular format,
| Feature | Java | JavaScript |
|---|
| Typed | It's a strongly typed language | It's a dynamic typed language |
| Paradigm | Object oriented programming | Prototype based programming |
| Scoping | Block scoped | Function-scoped |
| Concurrency | Thread based | event based |
| Memory | Uses more memory | Uses less memory. Hence it will be used for web pages
