Java vs JavaScript: how to choose between two programming languages

There are many languages in the world of programming, and some of the most popular ones are Java and JavaScript. Despite their similar names, these two languages have significant differences. In this article, we will look at the main aspects that will help you decide which is better to choose to learn: Java or JavaScript.

What is the difference between JavaScript and Java?

Before comparing Java and JavaScript, let’s understand their essence and purpose.

Java

Java is a statically typed, object-oriented programming language developed by Sun Microsystems (now part of Oracle). It is known for its reliability and scalability, and is widely used to create server-side applications, web applications, mobile applications (using the Android platform) and much more.

JavaScript

JavaScript, on the other hand, is a dynamically typed, interpreted programming language. It is mainly used to create interactive web pages and web applications. JavaScript runs in the user’s browser and allows dynamic behavior to be added to web pages.

Comparison of Java and JavaScript

Now let’s compare these two languages in terms of a few key criteria.

System type

Java

1. Static typing: Variable types are determined at compile time.
2. Compiles to bytecode, which runs on the Java Virtual Machine (JVM).

JavaScript

1. Dynamic typing: Variable types can change during execution.
2. An interpreted language that runs in the browser.

Scope of application

Java

• Creation of server applications.
• Android application development.
• Construction of large corporate systems.

JavaScript

• Creation of interactive web pages.
• Web application development.
• Managing the client side of web applications.

Difficulty learning

Java

Java is generally considered more difficult to learn, especially for beginners, due to its strong static typing and extensive standard libraries.

JavaScript

JavaScript can be more accessible to beginners since it doesn’t require upfront type declarations and can be used to quickly create simple web pages.

Which is better for a beginner: Java or JavaScript?

If you’re new to programming and unsure where to start, choosing between Java and JavaScript depends on your goals and interests.

• If you want to quickly start creating interactive web pages and get introduced to the world of web development, JavaScript may be a good place to start.
• If your interests lie in the field of server development, mobile applications or the creation of large enterprise systems, then Java will be a more suitable choice.

Conclusion

Ultimately, the choice between Java and JavaScript depends on your goals and preferences. Both languages have their own unique benefits and applications. No matter which language you decide to start with, it’s important to understand the features of each and continually learn to become a successful developer.
