Most new programmers are often confused between the two languages “Java and JavaScript“. Most of them find it difficult to choose which language to learn a first which won’t be a problem again after reading our guide to how to choose a programming language. For java and JavaScript, Their names might sound similar but they are completely different in all aspects which I’m going to explain in this article.

JavaScript.

JavaScript is a browser based language developed by a Netscape programmer in September 1995. Back then, the two most popular browsers were the internet explorer and Netscape navigator. It took just ten days to develop the language and the language and it was executed directly by the browser without the need of installing any other additional plug-ins or compiler. It was first called livescript but due to the popularity of a new language named Java, netscape engineers saw the need to rename their language JavaScript which attracted popularity to it.

console.log("Hello world!");

//Hello world syntax in JavaScript.

Java.

Java is an object oriented programming language created for sun’s Microsystems inc. by James Gosling in the early 1990’s. Developers of this language saw the need for computers and electronic devices to communicate with each other which led to the creation of the language.

Unlike JavaScript, Java doesn’t run directly on the browser as it needs a compiler for it to function. It is an object oriented programming language as everything needs to be put in a class for it to function.

class MyClass {
public static void main(String[ ] args) {
System.out.println("Hello World");
}
}

//Hello world syntax in Java.

Java is Platform Independent, which means that you only need to write the program once to be able to run it on a number of different platforms!
Java is portable, robust, and dynamic, with the ability to fit the needs of virtually any type of application.

Key differences between Java and JavaScript.

  • Java is an object oriented programming language while JavaScript is a scripting language.
  • Java can run on any virtual machine and browser while JavaScript runs only on the browser. Though a JavaScript framework node.js now runs on the server.
  • In Java, every program must belong to a class while programs in javaScript can be satistically written.
  • Java programs can run as a stand alone program while JavaScript programs needs to be embedded in HTML and CSS. see why you should learn html and css before JavaScript.
  • Java programs can be used in creating web based applications, mobile applications and other kinds of programs while JavaScript is used only to add interactivity to web pages and applications.
  • Java files uses a file extension of “.Java” while JavaScript files uses “.js” as it’s extension.
  • Java programs requires large amount of memory to run while JavaScript requires a lower amount of memory.
  • Java supports multi-threading while JavaScript doesn’t support multi-threading.

There you have it. The differences between Java and JavaScript all listed above. You might also want to see why HTML is not a programming language. Feel free to leave a comment below if you have anymore ideas you can share with us. We’d love that!
