Facebook is generally used for creating profiles and making friends, while LinkedIn is a business-oriented platform. But have you ever thought about how these platforms are developed? 

Absolutely Not!

These platforms are developed using programming languages. Facebook & LinkedIn are developed by JavaScript and Java, respectively. Most people think that these languages are similar as JavaScript has Java in its name. 

But actually, they are not?

They both are different languages. So. without wasting time, let’s take a look at them. 

Maybe, you know about Java vs JavaScript, but if you are a beginner, let’s take a look at them or if you already know about them, let’s recall them. 


Java is a class-based, general-purpose, object-oriented programming language. Also, it is used as a computing platform. Java is a most popular programming language used in application development. It is used for a variety of things such as:

  • Back-end development
  • OOP apps
  • Mobile apps
  • Big data analytics
  • Front-end development
  • Android apps
  • Hardware devices
  • Scientific computing apps
  • Server-side development technologies like Apache, and much more.


JavaScript was invented by Brandon Eich. It is a client-side, cross-platform, object-oriented scripting language. JavaScript is a popular web development language that is used to create dynamic and interactive web pages. There are numerous uses for JavaScript, including:

  • Creating a game
  • App creation for mobiles
  • App development for the web
  • Creating web servers and server software
  • Increasing the interactivity of web pages

Java vs JavaScript: Which is More Popular( As Per Google Trends)?

Both Java vs JavaScript are widely used programming languages and are highly in demand. The developers of Java vs JavaScript generate pretty good salaries. But, here you surely want to know which one is more popular? So, let’s take a look at the graphs of google trends and the TIOBE Index of December 2021, given below:

As the graph is shown, Java is more popular than JavaScript. But just because Java is in high demand as per trends doesn’t mean JavaScript is not popular. There are a variety of factors where JavaScript beats Java.

Similarities Between Java vs JavaScript

Although JavaScript vs Java are different languages. But they have a few similarities between them. Let’s take a look at the major similarities between Java vs JavaScript.

Support Browsers 

JavaScript supports modern web browsers. JS(JavaScript) makes web pages more dynamic and interactive. Browsers can use JavaScript to perform data validations, calculations, and various other tasks. Also, Java applications can run on web browsers in the form of applets. They take user input and change it according to the inlying code.

Libraries and Frameworks

Programmers can use language libraries and frameworks to access a variety of reusable general and purpose-specific codes. Also, developers can reduce their time by using these frameworks and libraries. Java vs JavaScript offers a variety of libraries and frameworks that may be used in many situations.

Object-Oriented Programming (OOPs) Language

Both Java vs JavaScript are object-oriented programming languages. They organize the program to collect objects & follow the main concepts of OOPs. 

  •  Abstraction
  • Encapsulation
  • Inheritance
  • Polymorphism

Even though Java vs JavaScript are similar in some factors, they are not identical. Let’s have a look at the differences between Java vs JavaScript.

Difference Between Java vs JavaScript

If you also think like other people do that Java vs JavaScript is similar or one language because of Java in their names. Then let’s clear your confusion and have a look at the difference between Java vs JavaScript. 

Concurrency Mechanism Java Concurrency has a thread-based approach.JavaScript Concurrency has an event-based approach.
Running Platform Java runs on a Java Virtual Machine environment.JavaScript runs only browsers, and now it runs on the server via node.js.
Java has a file extension named .Java. 
JavaScript has a file extension named .js.
LanguageJava is a standalone language. JavaScript is a prototype-based language.
Type checking Java is a Statically Typed language, and the variable is checked in compile-time in Java. JavaScript is a Dynamically typed language, and its syntax is very reliable. 
SyntaxSimilar to C++Similar to C
Salary The average salary of a Java developer is 74,000 USD per annum.The average salary of a JavaScript developer is 82,000 USD per annum.

Which is better, Java or JavaScript?

As you all know about the similarities and differences between Java vs JavaScript, here the question is which one is better for you. 

Both Java and JavaScript are suitable for web applications. On the other hand, Java applications are faster to execute since they are multithreaded, and the code is compiled all at once. However, it must be done on the server-side, which slows down its user engagement. As a result, JavaScript is the best choice for small, interactive web apps. Because the code is lighter and executed on the client-side, it allows for faster feedback and interaction.

Another advantage of JavaScript is that it takes less time to create. Web development in JavaScript is faster than in Java. However, Java is the best solution for large and complex desktop and mobile software.

Java is preferred for creating Android apps, enterprise software, and server-side technologies. It has an advantage because of the availability of APIs and third-party libraries.

Bonus Point

Java vs JavaScript: Which one has high salaries?

Java vs JavaScript are widely used and high-demand languages, and they also have high job opportunities and better career options. As you all read above about the Java and JavaScript similarities and differences and make your mind start with your interest language. Then let’s discuss that in Java vs JavaScript, which one is a high paying job. 

If we talk about Java developers, their annual salary is 77,428 USD. On the other hand, JavaScript developers’ annual salary is 85k USD. Now, you can choose your interest language between Java vs JavaScript, as now you know all the information to start with these languages. 


Java vs JavaScript both have their disadvantages and advantages. In simple words, it depends on your interest and what you want to do or accomplish. 

If you’re working with Android apps, scientific computing, big data analytics, or general-purpose programming, Java is the right choice. On the other hand, If you’re working on dynamic web page apps, front-end technology, or mobile app development, JavaScript is the right choice. Overall, it’s essential to analyse your project or work and research to ensure you’re using the correct language.
