Choice  for  2020 :  Java  v/s  Javascript

Both Java and Javascript have created a confusion in a person’s mind who is non-tech or new at programming, as both have commonality is the word “Java.” Many people assume that as JavaScript has “Java” in its name they both are somehow related.

Both programming languages are useful in their own regard, and each has strengths over the other. One isn’t necessarily better than the other; programmers use both Java and JavaScript for a variety of different tasks.

In earlier days, let’s go back to 2-3 years back, there would be a common difference between java and javascript that explained as- Java is a general-purpose coding language, and JavaScript is used for the web applications to make them interactive and animated. Now that JS has “grown-up,” the comparison is much more complicated here.

An Introduction:

JAVA: Java is a programming language invented by James Gosling and developed by Sun Microsystems. It took a little over 10 days to develop — it was close to four years old. In 1991, a group of Sun Microsystem engineers worked the “Green Team” day and night to create Java. It was first released in 1995, and many new versions have been launched since then. Today’s Internet is absolutely saturated with Java-based programming, and we have Java to thank for the many applications that make day-to-day life easier. Java is currently owned by Oracle.

JAVASCRIPT : In the early days of the Internet, around 1990, a developer named Brendan Eich at Netscape, Inc. was able to create a programming language that could instruct a computer to interact with the user upon receiving user input. He called this language “LiveScript” and integrated it directly into the navigator. This meant that the browser was literally interpreting the user’s commands; The code did not have to be compiled, and plug-ins were not required. Another programming language, Java, was gaining popularity around the same time, even though Java required a separate plug-in for the function. Netscape saw the opportunity and named its language “JavaScript”. JavaScript was unavoidable in the early days of the Internet.

Primary Similarities:

Although, both languages are separate but they have some top-level similarities, which are worth considering, especially if you are looking at web app development when comparing Java to JavaScript.

Object-Oriented Programming (OOP): Both languages ​​require the developer to code objects and their relationships in the context of each other. By extension, it gives both languages ​​access to technologies such as inheritance, encapsulation, and polymorphism.

Front-end development: Both languages ​​can be used in aspects of front-end development. JavaScript can be embedded directly into HTML, which is implemented as a framework or library; Java can be used as a Java applet.

Back-end development: Both languages ​​can be used on the server-side. Java has long been used to power back-end technologies such as Apache, JBoss, and WebSphere. Node.js has become a launchpad for JavaScript-powered servers.


Both JavaScript and Java are assembled, written and executed differently, and each has a dramatic difference when it comes to what it’s capable of.

Java is used in a wide range of places, including Android apps, credit card programming and in the creation of desktop applications and web enterprise applications. By comparison, JavaScript is mainly used to make web pages more interactive. It adds the animation in the HTML code.

In brief, When we want to know how each programming language works and different from each other, then in simple words, Java is typically used for all server-side development, while Javascript creating client-side scripts for tasks such as JS validation and interactivity is reserved for.


  • JavaScript code is all-text and Java code must be compiled.
  • Java programs require more memory whereas JavaScript requires less memory therefore it is used in web pages.
  • Each language needs different plug-ins.
  • JS code is run on a browser only, whereas Java creates web applications that run in a browser or virtual machine.
  • Java is an object-oriented programming language (OOP), and JS is specifically an object-oriented scripting language.
  • Java program has file extension “.Java” while Javascript program has file extension “.js”.

  • Conclusion

    Nowadays, software development companies in India and the rest of the world are using both of this programming language to create secure, scalable and feature-packed applications keeping in mind the requirements of businesses.

    Despite its industry age, Java is incredibly stable and not heading for retirement anytime soon. This makes Java one of the most desirable languages among programmers in 2020. JavaScript is a popular language among developers who need to work on server-side and client-side programming.You can learn java from ITC best java training institute in gurgaon and javascript training also.

    Finally, it’s an overview of comparison between Java and JavaScript. I hope you will have a good understanding of both languages. Now choice is yours for both languages, It is good to learn both Java and JavaScript as we can become full stack developers if we mastered it. As they are almost different languages, one will be used for most applications and backend programs whereas others will be used for making web applications, interactive effects/features using it which can run on different browsers.
