Which Should I Learn – Java or Javascript?

Has this question got you confused? If you are new to programming, then you have wondered about which programming language to choose. Java and JavaScript are excellent choices, but are they the same?

Despite the similarity in their names, these two languages couldn’t be more different from each other. In this article, we look at both what each of them does, and help you to choose.

Which Should Learn Java or Javascript


Java is an Object-oriented Programming (OOP) language developed by James Gosling at Sun MicroSystems (since acquired by Oracle) and was released in 1995. However, its origins are as a project called “Oak” earlier in 1991.

Java is a compiled language, meaning that it has to be converted to bytecode, which is understood by computers. Java is used to build enterprises, mobile, and embedded applications. Even the popular mobile operating system, Android is based on Java.


Java has come a long way since its beginning and has surpassed its contemporaries, such as C++, with many great features like automatic memory management and garbage collection. Let’s look at the advantages of Java over JavaScript.

Reusability is a major underlying theme of OOP concepts and is signified in Abstraction, Encapsulation, Inheritance, and Polymorphism. Reusability distinguishes Java from JavaScript with its clearly defined class structures and method definitions.
If you have no idea about these concepts, don’t worry. There are many good tutorials online, and CodeGym is an excellent place to start. They have many tutorials that are detailed and easy to understand.
Java is a complete application development platform, so it is well-suited for enterprise application development. Support through established libraries, integration capabilities, and hardware availability are just some of the main reasons to choose Java.

The Java Security Manager, which can control the access rules for the applications, makes Java applications run safer, eliminating harmful risks and threats. Performance and Efficiency can be improved by distributive computing, as Java is a distributed language.
Great Community support and Oracle premium support have made Java a reliable and robust platform. The high availability of both online and offline tutorials and resources makes it even more appealing to new programmers.


In comparison to JavaScript, the main problem of Java, especially for new programmers, is that it is more complicated to get a Java application up and running. Some prerequisites need to be satisfied, such as setting up the environment with the Java Development Kit (JDK), the Java Runtime Environment (JRE), and even an application server such as Tomcat if you want to create a web application that can be viewed on a browser.



JavaScript is a scripting language, and is one of the three main components of the web, along with HTML and CSS. One of its primary uses is to manipulate elements of an HTML web page dynamically without refreshing the entire page.
Founded by Brendan Eich in 1995 at Netscape Communications, it was initially called Mocha, and after that, LiveScript. The change of name to JavaScript came as part of its competition with Microsoft’s Internet Explorer and the popularity of Java at the time.
Nearly all modern web browsers support JavaScript due to its versatility and popularity. Even Microsoft began supporting JavaScript in its newly released Edge browser, which is gradually replacing Internet Explorer.


The main advantage that JavaScript boasts over Java is its simplicity. On its own, JavaScript requires nothing more than a simple text editor and a basic knowledge of HTML to get started.
There is also an equal or greater amount of community support for JavaScript, along with a multitude of online and offline training material, making it a very easy language to learn.


While JavaScript’s simplicity is beautiful, it is also where its disadvantages begin.

Due to being a scripting language, JavaScript is never able to perform on its own. Be it security vulnerabilities due to being visible to users, or lacking the features usually seen with other programming languages, JavaScript suffers in comparison to Java, with its compiler and full-fledged ecosystem.
Other concerns also include minor differences in the way individual browsers handle JavaScript, the inability to handle exceptions and errors without a page-wide failure, and having to write complicated code for even the smallest of tasks.


Comparison of Java and Javascript

Java or JavaScript? What have you understood up to now, and in which direction has it lead you?

By now, it should be evident to you that comparing Java and JavaScript is like comparing Apples and Oranges. They are very different from each other and are used for very different purposes.
Java is a full-fledged ecosystem for web, desktop, and mobile applications. It can be used to create a complete app, both back-end and front-end, while completely avoiding JavaScript. This has made Java the number one choice for many enterprise applications.

The Tiobe Index puts Java at the number one position or at least in the top 3 throughout its lifespan. Most companies (up to 95%) use java as their primary language. One billion downloads per year, and running in more than 1 billion devices makes Java the number one choice for programmers, especially for beginners.

JavaScript is more of a supporting language for HTML manipulation. It becomes more capable when used in conjunction with frameworks. But it still does not measure up to the level of robust and reliable programming languages like Java.

One other vital aspect to be considered by new programmers is career progression.
Given the popularity of Java and the level of integration it has with all types of applications and devices, it is hard to imagine the decline of Java in the foreseeable future. As such, there will be no shortage of jobs for a skilled and qualified Java programmer.

On the other hand, JavaScript, with the emergence of so many frameworks, such as React Native and Angular, is gradually becoming obsolete. While it is essential to have at least a basic knowledge of JavaScript, whether you become a Java programmer or not, the need is on the decline. There is no longer a need to know the detailed intricacies of JavaScript, as most of these are handled by the frameworks and their Integrated Development Environments (IDE).

Remuneration is an undeniable contributor to your career selection. The Bureau of Labor Statistics (BLS) of the United States states the median annual pay for Computer Programmers as $84,280. Other statistics show a range of between $65,000 – $132,00, with the average figures for Java programmers well above the average, at approximately $105,000. This, however, is with a considerable number of years of experience and depends on other factors such as education and the industry in which they are employed.

In comparison, the BLS shows an average figure of $69,430 for Web Developers, which is a typical occupation for a programmer with plain JavaScript knowledge and many years of experience.
Learning Java as your core programming language and getting a good understanding of it will not only transform you into an excellent programmer but also prepare you for learning many other languages, due to its strong foundation in OOP concepts.


As a programmer, it will be essential for you to learn JavaScript as it is widely used in many applications, irrespective of whether you become a Java programmer or not.
However, when it comes to building a career and choosing a programming language to do so, the obvious choice is Java, especially when comparing between Java and JavaScript.
So, we hope that we have been able to persuade you that Java is the way to go sufficiently!
