Which is faster Java or JavaScript?

JavaScript is an interpreted language that provides application developers some additional flexibility over Java implementations. JavaScript is relatively faster than Java because interpreters execute the source program code themselves. js that is designed particularly for the server-side runtime environment.

Why is Python slow?

Longer development time converts directly into extra costs, fewer features and slower time to market. Internally the reason that Python code executes more slowly is because code is interpreted at runtime instead of being compiled to native code at compile time. Other interpreted languages such as Java bytecode and .
