Paradigm	JavaScript is a multi-paradigm language that supports both object-oriented and functional programming styles.	Java is an object-oriented language that supports imperative and declarative programming styles.
Typing	JavaScript is a dynamically typed language, meaning that variable types are determined at runtime.	Java is a statically typed language, meaning that variable types are determined at compile time.
Performance	JavaScript is generally slower than Java due to its interpreted nature and lack of native multithreading support.	Java is generally faster than JavaScript due to its compiled nature and support for native multithreading.
Libraries and frameworks	JavaScript has a vast array of libraries and frameworks available, including React, Angular, and Vue for front-end development, and Node.js for back-end development.	Java has a wide range of libraries and frameworks available, including Spring and Hibernate for enterprise development, and Android for mobile development.
