Learn the Difference between Java and JavaScript

Home » Learn the Difference between Java and JavaScript

Java and JavaScript are not similar and they don’t have any connection between them. Java is a programming language that is commonly used across the world. But JavaScript is a scripting language that has gained the name after the popularity of the term ‘Java’. To know more about the difference between Java and JavaScript, continue reading this blog post.

What is Java?

Since its creation in 1995, Java has become one of the most widely used programming languages worldwide. Oracle currently owns it, and Java is run over 300 billion devices. To be more specific, the Java programming language supports the extensive creation of games, big data analysis, web servers, desktop applications, Android mobile applications, and other applications.

What is Java?

Java is a network-centric, general-purpose class-based, object-oriented programming language. Its primary goal is to reduce implementation dependencies. Java is a computing platform that is quick, dependable, and safe. As a result, many applications for laptops, Android phones, data centers, game consoles, and other devices rely on it.

Features of Java

The following are some significant features of Java.

  1. Easy-to-use programming language.
  2. Secured programming language. It doesn’t have pointers so it is impossible to access the out-of-bond arrays.
  3. Create code once and run it on any computing platform.
  4. Platform-independent. (i.e.) You can execute programs written in one machine in another machine.
  5. Designed for developing object-oriented applications. It covers all 4 important OOPS concepts such as abstraction, inheritance, encapsulation, and polymorphism.
  6. Multithreaded language with automatic memory management. (i.e.) allows concurrent execution of two or more parts of a program for maximum utilization of the CPU.
  7. Built for the distributed environment of the internet.
  8. Network-centric and hence it facilitates distributed computing.

What is JavaScript?

All web browsers support the well-known and open-source client-side scripting language JavaScript. Brendan Eich created the language for the first time in 1995. The language was originally known as LiveScript, but it was later renamed JavaScript.

The primary purpose of JavaScript is to improve how users interact with the website. Additionally, it is extensively utilized in the creation of mobile games and applications. The C programming language has the greatest influence on JavaScript’s syntax.

Features of JavaScript

Listed below are some prominent features of JavaScript.

  1. Lightweight and Dynamic programming language.
  2. An interpreted Programming language with object-oriented capabilities.
  3. Supports Open and Cross Platform. (i.e.) Compatible with all modern web browsers and runs on all Operating systems.
  4. Designed for building network-centric applications.
  5. Integrated with Java and HTML.
  6. It does not need a compiler.
  7. Handles date and time.
  8. Performs form validation through forms developed using HTML.

Java vs. JavaScript- A Comparison Table

Find here, the major differences between Java and JavaScript.

S.No Java JavaScript
1. Java is a programming language. JavaScript is a scripting language.
2. It is a pure object-oriented programming language. It is an object-based language.
3. Java is a standalone language. JavaScript integrates with HTML for execution and hence it is not a standalone language.
4. Java is a strongly typed language. JavaScript is a loosely typed language.
5. You can compile Java programs before execution. For execution, you need to integrate JavaScript into the HTML program.
6. It is a complex language to learn. It is a simple language that is easy to understand.
7. A web browser is not required to run Java programs. Mainly, Java requires a Java Development Kit(JDK) to run the code. To run JavaScript programs, any text editor or web browser console is necessary.
8. In Java, complicated tasks can be performed using multi-threading. In JavaScript, the users cannot perform complicated tasks.
9. Java requires a large amount of memory. JavaScript requires only less amount of memory.
10. Java program languages are saved with the .java extension. JavaScript programs are saved with a .js extension.
11. Java is stored on the host machine as “Byte” code. JavaScript is stored on the Host machine as the “source” text.
12. Java applications can run on any virtual machine (JVM) or browser. JavaScript runs on the web browser and the server via Node.js.
13. The objects of Java are class-based and no programs can be executed without creating a class. JavaScript objects are prototype-based.
14. Java has a thread-based approach to concurrency. JavaScript has an event-based approach to concurrency.
15. Java supports back-end development. JavaScript supports both the front-end and back-end development.



We hope you are now clear about the difference between Java and JavaScript. Particularly, to create Java and JavaScript programs, follow the appropriate syntaxes, and write the source code. In case, you are unsure how to develop Java and JavaScript programs, call us quickly.
