Dark Mode On/Off
In this post, we are going to know the difference between Java and JavaScript. Both are widely used by the programmers and each serves a different purpose. Let's see some of the major differences between them.
Java is a class-based, object-oriented programming language, which was first designed by James Gosling in the year 1995 while working at Sun Microsystems. The code compiled in Java once can be run on any platform without the need for recompilation, provided that the platform supports Java. It is one of the most popular programming languages, with over 12 million developers worldwide.
JavaScript is the programming language of the Web. Along with HTML and CSS, it is one of the central technologies of the World Wide Web. It is JS that makes our websites interactive and is supported by all the major web browsers.
Server-Side technologies like Apache, Hardware devices, application in scientific computing technologies, the corporate world, and a huge number of Android Apps are built with Java. ( Although, Google now officially supports Kotlin).
A few of the big companies which use Java are Twitter, Netflix, Uber, Spotify, Instagram, Pinterest, etc.
JS is also used to build mobile apps with the help of React Native, etc, Various server-side and front-end technologies like Node.js, MongoDB, jQuery, AngularJS, etc are based on it.
Examples of tech giants where JavaScript is used are PayPal, Groupon, Facebook, eBay, etc.

Pros:
Libraries can be easily navigated in Java.
Also, it is a multi-threaded environment, so we can do many tasks at once in the same program.
It allows us to create reusable codes and standard programs.
Also, it is used by a great number of developers worldwide, and its documentation is also available in detail easily.
Java is platform-independent, its programs are compiled in bytecode, thus allowing them to run on any platform that has JVM ( Java Virtual Machine ) installed on it.
Cons:
Garbage collection cannot be controlled in Java.
Also, low-level programming constructs are not supported by it.
Hardware cost in Java is huge because of its high requirement of processing and memory.
Its programs are comparatively a bit slow.
Pros:
It allows the user to create interactive web pages.
It can be used to store and retrieve information on the user's pc.
It supported cross-compilation.
Once compiled, it can run on any web browser.
It is open-source.
Cons:
It does not allow multiprocessing or multithreading features.
It cannot be used for networking applications.
Java is Static, JS is a dynamic language.
Code once written in Java can be run on any platform supporting it, JS is cross-platform.
Java's file extension is " .Java " , " .js" is the file extension of JavaScript.
Java is strongly typed, JS is weakly typed.
Java is a multi-platform, object-oriented, and network-centric, programming language whereas JavaScript is a scripting language that helps you create interactive web pages.
