Java vs. JavaScript: Which Language is More Productive for Programmers

by Anannya Agrawal professional trainer for mobile and web applicatio
Most often, people get confused between Java and JavaScript because of their terminology. Both may sound similar, but both the programming languages differ in terms of features and benefits. This article will help you understand the comprehensive comparison of Java vs. JavaScript.

What is Java?

Java is one of the most popular object-oriented programming languages used to develop applications with a file extension ‘.Java.’ As of January 2020, Java is the top-rated programming language with 16.896% ratings. Some of the popular websites built using Java include LinkedIn, Amazon, TCS, Infosys, and more.

What is JavaScript?

JavaScript or JS is the most popular scripting language that helps create dynamic and interactive websites and applications quickly. As of January 2020, JavaScript owns 2.451% of programming language market share. Many renowned sites such as Google, YouTube, Facebook, Twitter, Amazon, and more are built using JavaScript.

Now, let us have a look at some fascinating facts and stats about the two popular languages.


James Gosling invented Java language at Sun Microsystems. It was first released in 1995 and primarily known as “Oak.” It was later renamed to “Green,” and finally as “Java.”

Brendan Eich created JavaScript at Netscape Communications Corporation. Its first version, known as Mocha, was released in 1995. Its name was changed to LiveScript, and later, to “JavaScript.”


Java applications run in Java Virtual Machine (JVM), which requires the installation of the entire Java Development Kit (JDK) and Java Runtime Environment (JRE).

JavaScript application runs in a web browser, and hence, it does not require any pre-installation. You can even use the text editor to write JavaScript programs.

3.Learning Curve

If you wish to learn programming and develop web applications, Java has a wide range of documentation, online resources, and community support.

JavaScript is comparatively easy to understand and learn, even for beginners, as it has extensive documentation, online sources such as forums, video tutorials, and more.

4.Programming Syntax

In terms of syntax, Java is quite similar to C and C++ programming languages. It uses classes and objects to write programs.

While, on the other hand, JavaScript syntax matches with the C language, and it works on the prototype concept. However, it uses naming conventions similar to Java language.


Java is an entirely independent programming language and can run on any Operating System (OS).

Whereas JavaScript is supported by almost all the web browsers that come with different OS. And, its performance depends on CSS and HTML.


You can consider using Java for developing Desktop Applications, Business Applications, Web-based Applications, Cloud-based Applications, Mobile Applications, Games, Animations, and more. Also, Java is considered to be the future of trending technologies like Big Data and IoT.

You can consider working with JavaScript if your project involves Dynamic Single Page applications. Moreover, you can use it with front end technologies like jQuery, Angualr.JS, Backbone.js, and more.

Advantages of Java and JavaScript


•It works on Write Once, Run Everywhere (WORA) concept, which provides the ability to run the same program on different systems.
•It supports multithreading that enables you to perform multiple tasks simultaneously.
•As an object-oriented programming language, Java provides the ability to create modular programs and reusable code.
•Features such as exception handling, type checking, and automatic garbage collection make Java more popular among programmers.
•Java has extensive community support and excellent detailed documentation.


•You can insert JavaScript code into any web page, regardless of its file extension.
•The implementation of JS allows the client-side script to interact with users.
•JavaScript does not require the compilation process, so it offers fast debugging and testing.
•JavaScript is interoperable with other programming languages and can be used in numerous applications.

Disadvantages of Java and JavaScript


•Java compiler is significantly slower than C and C++
•Memory management is comparatively expensive in Java
•It lacks support for low-level programming constructs like pointers


•JavaScript is sometimes interpreted differently by different web browsers.
•It doesn’t support multithreading feature.
•Since the code executes on the client-side system, it is vulnerable to malicious activities.

So, with this, we hope that the article helped you to gain insights into the differences between Java and JavaScript. Indeed, both are popular and continue to reign supreme in the world of programming in their respective ways.

If you’re looking for a successful career in one of these robust programming languages, you must opt for an exclusively curated Java programming training course. So, enroll today and take the first step towards your technology career to develop intuitive desktop and web applications by gaining hands-on experience from the industry experts.
