Java vs JavaScript: Key Differences and Which One Is The Best Choice?

Share This

Both Java and JavaScript languages play an important role in the programming industry and have marked a prominent presence in the world of app and web development. And in this blog, the discussion will be about what Java is, what JavaScript is, the key features of Java and JavaScript, and how Java is different from JavaScript to help developers decide on which is the best option. 

What is Java?

Java is a multiplatform programming, platform-independent, object-oriented programming (OOP) language. The programming language is class-based and structured in such a way that code developers can write code anywhere and run it anywhere without worrying about the underlying computer architecture.

Features of Java

Java has become a popular programming language because of its excellent features. Here are the advanced features of Java programming are

  • Platform Independent
  • Portable
  • Architectural Neutral
  • Object-Oriented
  • Robust and Secure
  • Compiled and Interpreted
  • Multi-threaded and Interactive
  • High Performance
  • Dynamic and Extensible

Application of Java

  • OOP Apps
  • Android Apps
  • Enterprise Software
  • Programming of Hardware devices
  • Big Data Analytics
  • Scientific Applications
  • Server-Side Development Technologies like Apache, etc.


Advantage of Java

  • Simple - simple programming, straightforward, easy to write, learn, maintain, and understand, the code is easily debuggable.
  • Object-Oriented - object-oriented programming language that helps us to enhance the flexibility and reusability of the code.
  • Secured - a secured programming language reduces security threats and risks by avoiding the use of explicit pointers.
  • Robust - a robust programming language since it uses strong memory management.
  • Platform Independent - a platform-independent code that can run on multiple platforms.
  • Multi-Threaded - a multi-threaded environment in which a bigger task can be converted into various threads and run separately.

What is JavaScript?

JavaScript is a lightweight programming language, also called a scripting language that enables developers to create interactive web pages. It is a very powerful client-side scripting language that allows the creation of dynamic content for the web. It provides the basis for certain frontend technologies, such as jQuery, AngularJS, and ReactJS.

Features of JavaScript

JavaScript has become a popular programming language because of its excellent features. Here are the advanced features of JavaScript programming are

  • Validating User’s Input
  • Object-Centred Script Language
  • Client-side Calculations
  • perform In Built Function
  • Case Sensitive 
  • Light Weight and delicate
  • Statements Looping
  • Handling Events

Application of JavaScript

  • Game Creation
  • Mobile App Creation
  • App development for the web
  • Creating web servers and server software
  • Increasing the interactivity of web pages

Advantages of JavaScript

  • Speed - very fast because it can be run immediately within the client-side browser.
  • Simplicity - simple to learn and implement.
  • Interoperability - works perfectly with other programming languages.
  • Server Load - client-side reduces the demand on the website server.
  • Rich Interfaces - provides various interfaces to developers for creating catchy webpages.

Similarities Between Java vs JavaScript

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

  • Support Browsers 
  • Libraries and Frameworks
  • Object-Oriented Programming (OOPs) Language

Java vs JavaScript: Which One is Best

Both Java and JavaScript are high-demand languages, that are suitable for web applications. For Web development, JavaScript is faster than Java. JavaScript is the best choice for small, interactive web apps and it takes less time to create. Java is faster to execute because it is multithreaded, and the code is compiled all at once. Java is the best solution for large and complex desktop and mobile software often preferred for developing Android applications, Enterprise software, and server-side technologies. JavaScript offers a lighter code that is executed on the client-side and is the best choice when developing small and interactive web applications.

Final Thoughts

Both Java and JavaScript are widely used languages, and may sound similar but are extremely different and unrelated. It is important to understand the differences between Java and JavaScript before deciding which is best for your project. Now you got a profound idea about the similarities and differences between Java and JavaScript. Both languages have their advantages, which make them suitable for one development scenario. It is essential to analyse your project and understand the programming language used for your project to ensure you are using the correct language.
