If you’ve been researching for building an app or a web page or to learn a new programming language, you might have come across Java and JavaScript. Both are very popular for web and app development as well as server programming, and if you’re looking to do any of these, it is essential to know the difference between Java and JavaScript.

Back in the early days of the internet, there were two leading web browsers NetscapeNavigator and Internet Explorer. Over the years Netscape Navigator lost traction as Microsoft’s Internet Explorer gained a lot of popularity.

Javascript was created in 1995 by Brendan Eich, a Netscape Corporation programmer. During the same year, James Gosling developed Java at Sun Microsystems. When Java came in the market, it gained a lot of popularity due to its object-oriented architecture and better security as it did not use pointers. Arguably, due to this reason when Javascript was created, it included Java in its name to gain popularity by way of relatability.

Java vs JavaScript

JavaScript is a prevalent client based scripting language, whereas Java is a general-purpose programming language. Both of these programming languages are different from one another. The only similarity between the two languages is the name Java.

We will be talking about both these languages in great detail. This will give you a clear idea about both of these languages and what makes them different.

JavaScript is a programming language which runs on your web browser. It was considered a client-based scripting language, but it has evolved a lot since it came into being.What's the difference between Java and Javascript?JavaScript works as an interpreter-based programming language that evaluates each line of code individually. It is a weakly typed language, making webpages more interactive. If you see any animations on a webpage, JavaScript is behind making it possible.

JavaScript instructs the web browser on what to do for any user input. It has gained a lot of popularity due to a lot of advantages that it has over other options like flash script. Due to its client-based architecture, it can run entirely on your web browser. This puts less load on the server and makes websites faster.

JavaScript has evolved a lot since its creation in 1995 and branched out into several other sub-languages. Node.js is a server-based scripting language used for back end development. Angular.js is another version of javascript prevalent in front end development. JavaScript is also going to use machine learning with TensorFlow.js. One can say that javascript has come a long way since it was created and is no longer just a client-based scripting language.

Java is a general-purpose programming language which needs a Java virtual machine to run. Any application development that comes to your mind can be performed using Java.

Be it banking, information technology or android app development; Java is used everywhere. It is an object-oriented programming language which offers abstraction, encapsulation, inheritance, and polymorphism.

All these features make it an excellent choice for any kind of application development. It is a compiler-based language and does not evaluate a single line of code like JavaScript. Unlike JavaScript, it is a  strongly typed language. Being a general-purpose programming language, Java uses more memory compared to JavaScript.
