- Java is an object-oriented programming language developed under the slogan “Write once, run anywhere.” It was originally developed by Sun Microsystems in 1995 and later acquired by Oracle. Java is widely used in the enterprise environment for proprietary software and Android development. Its syntax was influenced by C and C++.
Besides, JS is good for analytics and web tracking. You can adjust your business strategy based on page views and click tracking. Such simple – from a customer’s point of view – actions like loading an abandoned shopping cart can make a big difference for your business.
What is Java used for? It was originally invented for smart home appliances, but many large companies wanted to use Java in their products upon seeing its convenience and flexibility. It’s used to develop server software, desktop programs, and applications for Android-based devices. It is also used in software for various household smart devices and even Tesla electric vehicles.
In Github’s 2020 State of the Octoverse, Java takes third place in the popularity report. Although it had experienced a small drop for the previous two years, the Java developers have stayed loyal to this language since 2014.
Java is an object-oriented, “industrial” programming language. It runs payment terminals, smart devices, and huge server systems. For many, it’s associated with gigantic corporations, endless server rooms, and financial markets. The main feature of Java is adaptivity. Java code written on one platform will run on other devices. Software written in this language runs on Java Virtual Machine, which provides code optimization and memory management.
Java is highly popular in many fields – from Android apps to backend systems. Google, YouTube, Facebook, eBay, and Amazon use it in their backend development. Square, the world leader in digital payments and financial services, uses a Java-based cash transaction stack.
Java’s deep integration in the enterprise world means that the language is very conservative and somewhat stagnant. Since it became a “mature” language a long time ago, any new breaking changes are sacrificed to keep maximum backward compatibility and predictability. This fact is particularly relevant for building large backend infrastructures and proprietary software for international corporations.
The aim of any comparison between these two languages is not to decide whether either of them is “better.” They have almost the opposite core values, which emerged historically through the process of their usage.
- Cross-Platform Features
Both languages run on the additional layer of abstraction, which acts as a virtual machine, providing a 100% compatible environment for code to run. For Java, it is JVM (Java Virtual Machine) while JS runs in any modern browser or on its core software like Chromium or a web server like Node.js.
Java is a proven backend-only language. Besides, its cross-platform features are utilized a lot more compared to JS. Smartphones, web, desktop software, or embedded systems – Java is everywhere.
- Historical Usage
Java is highly popular in the financial and government sectors, embedded systems, and Android development. Natural language processing systems are also often written in Java.
Java is usually a prerogative of conservative, experienced professionals. Industry giants opt for this language when creating complex proprietary systems.
