Many people genuinely assume that java and javascript are interchangeable terms for the same language or that they are related languages. However that user must clear any confusion regarding the fact that javascript and java programming language are not related languages and have nothing to do with one another. the popularity of the java programming language, which was at its height at the time, was the biggest factor behind the introduction of the scripting language called javascript. Let us debate Java Vs JavaSript and understand more about it.

- Java is used to perform complex tasks, while in javascript complex tasks cannot be executed.
- Java programs are saved with the .java extension. javascript programs are saved with the javascript .js extension.
- Java is stored in the client host machine under the byte code. while javascript stores in host or client machine as source code.
- java compiled on the server before it is executed on the client side. javascript is interpreted on the client side.
- Java requires a java development kit(JDK) to run the code. JavaScript requires any text editor or browser console to run the code.
- Java uses more memory. Javascript uses less memory.
- java support multithreading. Javascript doesn't support multi-threading.
- java is static and the code once written can be run on any computing platform, while the javascript is dynamic and is a cross-platform language.
