Java vs. JavaScript: Differences and Similarities

Are you confused about the concept of Java vs Javascript? Fortunately, you are not the only one who has this confusion. Even the majority of masses think that Java and JavaScript are the same. The major reason behind their mindset is that JavaScript has “Java” in its name. 

Apart from this fact that both are similar or different, both of these are essential in the I.T. sector. So let us focus on getting plenty of information about the topic of Java vs. Javascript. In this blog, we will explicate the similarities, differences, and definitions of Java and JavaScript. 

So stay tuned with us!


Firstly let us be aware: what is Java?

Here is your answer!!

Java is categorized as the class based-programming language which executes in the JVM. Here the term JVM stands for the Java Virtual Machine. Due to it, Java runs on any platform. Moving to its history, this programming language was established by the Sun Microsystem. 

The features of a secured environment and great compatibility make it one of the major programming languages. In addition to that, most firms give preference to Java to build the applications and back-end system. As a result, demand for Java developers is at its peak. 

Besides this, Java will assure you about: “Write Once, Run Anywhere.” 


The lightweight programming language is also known as the scripting language. The major purpose of using Javascript is to make the web pages interactive. In addition to that, JavaScript is also named as the browser’s language. 

 In the commencing days of the internet, it means nearly 1990, the two most popular browsers were used. These were internet explorer and Netscape Navigator. Within ten days, Brendan Eich at Netscape, Inc, a developer, created the programming languages. 

He gave the name to that programming language “LiveScript.” At the same time, Java was gaining immense popularity. Netscape observed this opportunity and gave the name to its language, “JavaScript.”  

Both of these programming languages have the C-like syntax, but that does not mean it is similar.

The interesting facts about Java and Javascript:

  • Initially, Java was known as the “Oak.” Further, the marketing department of Sun changed its name to “Java.” 
  • Java programming language was developed accidentally. It commenced with the “cleaning up” of the C++ language. In around1992, James Gosling was doing the work at Sun Labs. He and his team were working on manufacturing the set-top box. However, in the end, they wrap with the exclusive programming language that is Java.
  • Java operates on more than 1 billion in this present scenario, and the Google Android Operating system prefers the Java APIs.

Java vs. JavaScript: Differences

This section is useful for those masses who think that Java and JavaScript are both similar languages. In addition to that, the below-mentioned table will resolve all of your queries about: how both of these languages are different from each other:

Strongly type languageWeakly type language but more relaxation in syntax and rules.
Object oriented language Object based scripting language
Operate in any JVMCode usually preferred only in browsers
Objects are class basedObjects are prototype based
Comes with the file extension that is “.Java”Comes with file extension of “.js”.
Requires more memoryUse less memory
Has the approach of thread basedInclude event based approach
Supports multithreading Does not provide support to multi-threading

Similarities between the Java and JavaScript:

Apart from the differences, both of these languages have some similarities too. Now your question will be: How are Java and JavaScript both similar? 

Have Patience; here is your solution to that query:

  • Object-Oriented Programming 

Either it is Java or JavaScript; both of these need the developer to code objects. With the help of extensions, it provides both languages access to technologies. It includes inheritance, polymorphism, encapsulation, and so on. 

  • Front-End Development:

Both of these languages can be used in front-end development. The JavaScript can be embedded directly into the HTML. On the other hand, Java can be preferred as the Java applet.

  • Back-end development 

Like the front-end development, both of these languages are required in the back-end development. Java is required in Apache, JBoss, and so on. 

These are some similarities that you can find while learning more about Java and JavaScript. 

Benefits of using JavaScript:

There are numerous benefits associated with JavaScript and Java. So, let us consider some benefits of using JavaScript.

  • Client-Side Scripting Languages 

The complete source code is developed in JavaScript. Further, it is executed on the client’s browser. 

  • Powerful framework

It is prominent for offering numerous powerful and robust frameworks. Both of these are fruitful in the process of development. In addition to that, the framework provides you with ready-to-use codes. These codes can be easily debugged. 

  • Concurrency 

This sort of programming language is used in executing numerous tasks at the same time. Coders have the opportunity of operating numerous tasks at one moment. 

Apart from it, JavaScript becomes an essential part of Uber, Netflix, and many big names. 

In the end, after reading the information mentioned earlier, now you will come to the decision of which one is better among Java vs. JavaScript. There are plenty of courses available online. In addition to it, you can learn either Java or JavaScript as per your interest. So, make your career as a developer.
