What are the similarities and differences between Java and JavaScript?

Before we go into the details of Java vs. JavaScript, let’s have a look at some of the significant commonalities between the two.

Object-Oriented Programming

Object-Oriented Programming (OOP) is a type of programming that uses objects to solve (OOP). Both of these programming languages contain code for generating objects and their interrelationships. In addition, various qualities implanted in these languages, like inheritance, encapsulation, and polymorphism, can be accessed.


Both Java and JavaScript are browser compatible, which means they can run in the same browser. Because JavaScript is consistent with most modern web browsers, it is a popular choice for web development. On the other hand, Java Applets are also run in a browser. On the other hand, Java Applets are less common due to difficulties with compatibility and security.

Development of the front-end

Did you know that the most common languages for web app development are Java and JavaScript? Java can be used as a Java applet to create appealing front-ends. According to statistics, Java and JavaScript are used by more than 90% of businesses. After being incorporated directly into HTML, JavaScript is utilized as a framework or library for front-end development.

Back-end programming

On the server, both Java and JavaScript are used. Programmers have used Java to support backend technologies, including JBoss, WebSphere, and Apache. Node.js provides the necessary infrastructure for the backend development of JavaScript servers.

What’s the Difference Between Java and JavaScript?

These days, Java vs. JavaScript is a significant issue of debate. Because it is performed on the Java Virtual Machine, Java is a platform-independent Object-Oriented Programming language (JVM). On the other hand, JavaScript is an object-oriented scripting language that aids in creating dynamic HTML pages.


While Java is utilized for all server-side development, JavaScript is mainly used for client-side scripts like JS validation and interactivity.

Different applications run in different ways

When discussing Java vs. JavaScript, it’s crucial to understand how these apps work. Applications are written in Java or JavaScript run in quite different ways. Java creates apps that can run in a browser or virtual machine, whereas JavaScript creates applications that can only run in a browser.


Android applications, desktop application development, and banking and finance app development are examples of where Java applications are used. On the other hand, the use of JavaScript is restricted to making web programs more interactive and creative. It also assists in the creation of HTML animations.

Compilation vs. Interpretation

JavaScript is an interpreted scripting language, whereas Java is a compilation language. Both of these languages work in different ways. JavaScript is evaluated immediately by a browser in its written syntax, whereas Java code is compiled into bytecode and run on the Java Virtual Machine.

Advantages of using Java

Java continues to be a key player in the software development market. The advantages of adopting Java are numerous. Because Java is an object-oriented and class-based general-purpose programming language, it’s a high-level language with multi-threading capabilities. The following are some of the significant benefits that Java provides to its users:


One of the essential characteristics of Java is that it is platform agnostic. Java allows you to write programs that operate on PCs, mobile devices, and embedded systems. Because the programs are compiled as bytecode, they can run on any platform with a JVM installed. Regardless of the platform, all Java programs are compiled.

Extensible and Dynamic

Java is a dynamic programming language. In Java, all classes, objects, methods, and libraries are dynamically linked. Various functions written in other languages, such as C and C++, are supported by this extensible language.


Java is an object-oriented programming language that allows you to do multiple things simultaneously. Java can accomplish various tasks at the same time since it enables multi-threading.

Secure and robust

Java provides a secure environment in which to develop apps. It guards against viral attacks and ensures that resources aren’t wasted. Exception handling is used to eliminate errors and limit the chance of crashing.
