Should You Learn Java Or JavaScript: Which Is Best?

Learn about Java and JavaScript

Java and JavaScript are two different programming languages with different syntax and purposes. Let's go over some key points about these two languages:


Java is one of the most versatile programming languages in the world and is used almost everywhere, including platforms, technologies, and various economic fields, especially in mobile development (Android). It is also widely used in programming cloud-based solutions and in other technology fields such as IoT and Big Data.


Currently, JavaScript dominates the field of modern frontend development. It is a multi-paradigm, high-level, and dynamically-typed programming language. In addition to being used to build applications and websites, JavaScript can also be used to develop desktop applications and server-side programs through Electron and Node.js.

Java and JavaScript are two completely different programming languages with different characteristics and applications. However, this article will not focus on that issue. To understand more, please read: Java and JavaScript - key differences.

Should I choose to learn Java or JavaScript?

So should I learn Java or JavaScript? Actually, there is no definitive answer to this question; it will depend on your needs and desires when learning programming. If you can't decide which language to learn, you can consider some factors.

Consideration factors

Here are some factors you should consider before deciding to learn Java or JavaScript:


Popularity reflects, to some extent, the market demand for a particular language or, in other words, the job opportunities available for that language. According to the Stack Overflow survey in 2021, JavaScript is still the most popular programming language and has been widely used for nearly a decade. Additionally, Java is also very popular, with 35.35% of developers stating that they use Java daily.

It can be said that both Java and JavaScript are mature programming languages, so they both have large programming communities and a vast array of useful tools, libraries, and frameworks to support the learning process.

When considering programming languages, JavaScript currently has an advantage over Java. If you don't have a clear programming learning path yet, JavaScript can be a good choice to start with. However, if you already have a specific programming direction you want to pursue, consider the following factors before deciding whether to learn Java or JavaScript.

Development direction

Development direction is crucial in determining the knowledge and programming skills you need, especially for beginners, to quickly achieve their learning goals.

                                                     In which field do you want to work?

If you are oriented towards development in the following areas, Java would be an excellent choice:

- Developing server-side web applications.
- Developing desktop and mobile platform games.
- Developing highly secure applications.
- Designing applications for the Android operating system.
- Working in the field of embedded programming.
- Supporting various fields such as Big Data and IoT.

On the other hand, if you are inclined towards development in the following areas, learning JavaScript would be reasonable:

- Developing client-side web and server applications.
- Developing web-based platform games.
- Developing mobile apps.

By choosing Java, you will have opportunities to develop and work in various fields. In particular, if you want to work in high-tech areas like IoT and Big Data, Java is definitely a consideration. However, JavaScript is also evolving with diverse supporting tools. Currently, JavaScript is being applied in high-tech fields as well. Although it is not as popular as other programming languages, the potential of JavaScript cannot be denied.

If you are still undecided about whether to learn Java or JavaScript, I suggest seeking the opinions of experts and seasoned programmers to see how they assess these two languages.

Should I learn Java or JavaScript?

In general, both Java and JavaScript are programming languages that are easy to learn and have various applications. Therefore, as a beginner, you don't need to be overly concerned about choosing which language to start with. You can consider the factors mentioned above to make a decision that suits your needs.

Furthermore, if you aspire to become a professional programmer, you will eventually need to understand or learn 1-2 other programming languages. The reason is that during your work, you will certainly come across different projects developed using different programming languages. Therefore, knowing more than one language is necessary for efficient work. The important thing is your current and future development direction (if you want to diversify your skills).

Advice when learning Java or JavaScript:

Regardless of which programming language you choose to learn, you are still the most essential and important factor for success.

Focus on the fundamentals: Don't rush into complex tools and libraries. Instead, take the time to understand the structure, syntax, and principles of the language. This will help you grasp the knowledge firmly and apply it flexibly to real-world projects.

Emphasize practical experience: Programming is a hands-on skill. Start with small steps by solving exercises to solidify your understanding of the operations. From there, build and complete personal projects to apply the knowledge you have learned and improve your programming skills.

Learn from the community: Both Java and JavaScript have a vast and supportive community. Therefore, participate in forums, social media groups, and read materials and articles from experienced individuals in the field to learn and stay updated with new knowledge.

Don't hesitate to ask: When faced with difficulties or questions, don't hesitate to ask and discuss with experienced individuals. They will help you clarify and provide better guidance during the learning process.

Learn how to self-study: In the field of information technology, the ability to self-study and continuously update knowledge is crucial. While guidance from others is valuable, train yourself in the skills of self-learning and searching for information to solve problems.
