Key differences between Java and JavaScript

Characteristic	Java	JavaScript
Syntax	Java has a C-style syntax, which is similar to C++ and C#. It uses semicolons to end statements and curly braces to define code blocks.	JavaScript has a syntax that is similar to C-style languages, but it also has some unique features. It uses semicolons to end statements and curly braces to define code blocks, but it also has dynamic typing and supports functional programming.
Paradigm	Java is an object-oriented programming language that supports imperative and declarative programming paradigms.	JavaScript is a multi-paradigm language that supports object-oriented, imperative, and functional programming paradigms.
Typing	Java is a statically typed language, which means that variable types are checked at compile time.	JavaScript is a dynamically typed language, which means that variable types are checked at runtime.
Performance	Java is known for its high performance and is often used for enterprise-level applications.	JavaScript is not as performant as Java, but it is still widely used for web development and other applications.
Libraries and frameworks	Java has a vast array of libraries and frameworks, including Spring, Hibernate, and Struts.	JavaScript has a large number of libraries and frameworks, including React, Angular, and Vue.js.
Community and support	Java has a large and active community, with many resources available for learning and development.	JavaScript has a massive community and is one of the most popular programming languages in the world. There are many resources available for learning and development.
Learning curve	Java has a steep learning curve, as it is a complex language with many features and concepts to master.	JavaScript has a relatively low learning curve, as it is easy to get started with and has a simple syntax. However, it can become more complex as you delve deeper into the language.
