Java vs JavaScript: Major Similarities & Difference



Do you know that the Java programming language is used in many places, including Android applications, the development of banking, financial apps, and the creation of desktop applications? However, in comparison to Java, the limited use of javascript is to make web apps more creative and interactive. Along with this, there are many differences between Java vs JavaScript. In this blog, we will cover the difference between these two words in detail.

What is Java?

Java is a multi-platform, network-centric, and object-oriented programming language. It is one of the most popular and widely used programming languages.

As well, also use this language as a computing platform. It was first released in 1995 by Sun Microsystems. Later, it was acquired by Oracle Corporation.

What is javascript?

JavaScript is a scripting language that usually helps you create interactive and creative web pages. It follows the rules of clean-side programming, so it runs from the web server in the user’s web browser without requiring any resources.

In addition, you can also use a JavaScript programming language with other technologies such as XML, REST APIs, and many more.

Major similarities between Java vs javascript

There are also some similarities in Java and JavaScript programming languages, which are as follows.

Support object-oriented programming (OOP)

Both java and javascript languages are multi-paradigm languages, which means these languages support more than one programming style. In other words, Java and Javascript languages support object-oriented programming.

Front-End Development

The use of both languages like java and javascript in the aspect of front-end development. JavaScript programming language can be embedded straightly into HTML and implemented as a library or framework. In addition, the use of Java as a java applet.

Back-End Development

One of the major similarities between java vs javascript is back-end development. Both languages offer server-side support. As well, the java programming language supports major backend technologies like Apache, JBoss, and WebSphere. Node.Js server JavaScript-powered server.

Java vs JavaScript: What’s the difference?

Java and JavaScript play a vital role in the IT industry. In the following section, we will compare the difference between two languages java vs javascript.

Type of language

Java is an object-oriented programming language that is a platform-independent language because it is executed on the Java Virtual Machine.

On the other hand, JavaScript is an object-oriented scripting language that widely helps to make dynamic HTML pages.


The use of Java programming language is usually in multiple places which include, the creation of desktop applications, Android applications, development of banking, and financial apps.

Whereas the limited use of JavaScript programming language to make web apps more creative and interactive. In addition, it also helps in making animation in HTML.

Application run differently

It is also important to know the difference between Java vs JavaScript about how applications run in both languages. Applications made either using these two programming languages ​​run completely differently.

The Java language develops applications that can be run on browsers and virtual machines. On the other hand, applications built using JavaScript can run on a browser only.


The use of Java for all server-side development. The server-side development refers to operations and programs that run on the server. Whereas the use of JavaScript is basically for writing client-side scripts for tasks such as interactivity and JS validation.

Compiled vs Interpreted

Java programming language is a compiling language. On the other hand, JavaScript is an interpreted scripting language.

Moreover, the complied of Java code into bytecode and generally runs on Java Virtual Machine. Whereas the interpretation of JavaScript is directly by a browser in the syntax in which the code is written.


 Java programming language uses syntax that is similar to C++ or C programming language. Whereas JavaScript language uses a syntax that is similar to the C language.


The statically typed programming language of java. In these programs, all the variables need to be delayed before they can be deployed and initialized.

Whereas on the other hand, the dynamically typed language of JavaScript programming.


Java Programming language utilizes a thread-based approach. The division of his approach to the program into small pieces of code in the hardware, which is run concurrently. In addition, this makes it faster and requires less overhead.

Whereas the JavaScript programming language uses an event-based approach. The Event-based approach divides the work by using event loops, callbacks, and queues.

Thus, these are the differences between the java and javascript programming languages.


We hope that this blog on Java vs JavaScript helped you understand the similarities and differences between these two programming languages.

Basically, the use of java and javascript languages widely in the development industry. Both languages provide OOP concepts such as polymorphism, and abstraction to make secure and interactive web applications.

Furthermore, if you learn the Java language then your career moves toward cloud engineering, back-end engineering position, and big data. If you learn JavaScript, you can learn to move toward front-end applications and UI/UX companies that use Node.js.
