Key Difference between Java and JavaScript

In the digital world of technology, Java and JavaScript is used by every programmer for doing a variety of tasks. Both are programming or scripting languages that cannot be compared in terms of their uses and strengths, as both run on different plugins.

All you need is good knowledge and skills to become successful in this field. Go through this article to learn about Java and JavaScript and all the important things required for developing full-fledged applications.

What is Java?

Java is an object-oriented programming (OOP) language, which allows you to create compiled programs for developing complex applications. It was released in 1995, and developed by the Sun Microsystem. Java is also utilized as a computing platform. It can run on virtual machines, where the code for Java needs to be compiled.

Features of Java and JavaScript

Features of Java

  • This programming language is robust and able to detect errors that are not easy to identify by another programming language.
  • With the help of Java programming language, we can create distributed applications.
  • It also supports multithreading which permits concurrent execution of two or more parts of a program for maximum utilization of the CPU.
  • There are four pillars of object-oriented programming language concept which are-
  1. Abstraction.
  2. Encapsulation.
  3. Inheritance.
  4. Polymorphism.

What is JavaScript?

JavaScript is a scripting programming language which is used to make web pages more interactive. It is also known as a browser's language, it can also insert dynamic text into HTML. JavaScript is not related and similar to Java. Both the programming languages have C-like syntax and are extensively used in server-side and client-side Web applications.
JavaScript was designed to work along with HTML as well as CSS to attain greater interactivity in the web browser experience. With its simplicity feature, it can be run in lightweight applications just like a browser.

Features of JavaScript

It was created for DOM manipulation, when JavaScript was created dynamic websites were made.
JavaScript can handle data as well as time.
No compiler is required in JavaScript.
JavaScript does not require a large amount of memory.
Performs Form validation even if the forms are created using HTML.
JavaScript is used for both backend and frontend.

Key Difference between Java and JavaScript

Java JavaScript
Java is an object-oriented programming (OOP) language, used for developing complex applications of enterprise. JavaScript is an object-based scripting language, used for creating dynamic and interactive web pages.
This programming language was established by Sun Microsystems. The JavaScript programming language was established by Netscape.
It is a standalone language and should be compiled before execution of any operation. JavaScript is an integrated HTML program for operations.
Java is used for performing complex tasks. Complex tasks cannot be executed by JavaScript.
To run Java programs, a web browser is not required. To run JavaScript programs, web browsers play an essential role.
Java is one of the intricate languages to learn. JavaScript is an easy language to learn.
In the Java programming language, all the programs are saved with the .java extension. In JavaScript programs are saved with the .js extension.
Java requires a large amount of memory. On the other hand, JavaScript does not require a large amount of memory.
Java upholds multithreading, which permits different strings of execution to run simultaneously inside a solitary program. JavaScript doesn't uphold multithreading, even though it can stimulate it with the use of web workers.
It has a thread-based approach to concurrency. It has an event-based approach to concurrency.
Java has a rich set of frameworks as well as libraries for creating enterprise applications, like Struts, Spring, and Hibernate. JavaScript has an extensive variety of frameworks and libraries that help in building web applications like Vue, React, and Angular.
It is mainly used for the backend. It is used for both the backend and frontend.
To run the code, Java requires JDK (Java Development Kit). To run the code, it requires any text editor or browser console.
It is used on server-side for creating web applications, and for mobile as well as desktop applications. It is mainly used on the client side for creating web applications. JavaScript can also be used on server side with technologies such as Node.js.
Objects of Java are class-based, without creating a class we cannot make any program in Java. Objects are prototype-based in JavaScript.
