CODING 101: Java vs. JavaScript

One of the most common confusions in programming languages is Java vs. Javascript. They sound so similar, they must be related, right?

For our readers only, here’s a pro tip: Java is Not JavaScript!

In short, Java is a backend programming language, while JavaScript is a frontend language.

If the above doesn’t mean anything to you — here’s a longer description:

Java can be used to create complete applications that may run on a single computer or be distributed among different computers in a network. Java is generally used by developers to program applications. It allows developers to“write once, run anywhere” (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

JavaScript is the most advanced language alongside HTML and CSS and enables us to interact with users in form of sliders, drop-down menus, quizzes, and many more interactive elements. Developers use JavaScript only inside of web pages.

What is built by Java, and JavaScript?


  • Android: Android itself, as an operating system, is written in Java, and most Android apps are written in Java.
  • Minecraft: Minecraft was originally developed in Java, but has since been adapted in other languages for different platforms (such as C++ for iOS)
  • Eclipse: For developers, It’s a multi language multi platform IDE that is written in Java.

What should I learn first, then?

While both Java and JavaScript can be used as web languages, yet it is important for aspiring programmers to learn JavaScript. Due to slow speed, Java is not used often by developers on the web.

Worth mentioning is that Java is historically one of the main languages taught in universities globally as a CS101 language. Java is an object oriented programming language which provides a very valuable foundation for anyone who’s serious in learning about programming. We highly recommend K-12 students to learn Java once they gain a solid grasp of their first programming language.
