Even though Java and JavaScript have the word Java in their names, the two are used in different contexts at development. Java is the solid and stable platform on which large applications can be developed with consistent quality, JavaScript is the fast and active performer that brings richness to the web application. In this tutorial we will provide you a comparison of java and javascript.

Java:

Java is class-based object-oriented programming language and is widely used in developing applications that can work on any Operating System and the security is well provided. Sun Microsystems created it and is now a part of Oracle, and this technology was released in 1995. Java is based on the Write once, Run anywhere (WORA) model; however compiled byte code will run on any Java enabled virtual machine.

Key characteristics: 

Platform Independence: There is Java’s “Write once, Run anywhere” (WORA) principle established. This means you can compile Java code on any tool with a JVM from supercomputers to smartphones. 

Robustness: Java’s type system, exception handling, and rubbish series are or contribute to reliability because it is Java is designed to handle errors gently and does not crash easily. Generics: It allows developers to write safe code as code type is checked and optimized for better performance at compile time.

object-oriented: Java is designed based on the concept of objects, the concept that brings about features of reusability and modularity.

Multi-threaded: Java can handle several jobs at once leading to substantive improvement of software response rates.

JavaScript Overview

JavaScript is a high-level and interpreted programming language, and, together with HTML and CSS, is regarded as a center era of the World Wide Web. When used effectively JS allows developers to have a dynamic and active webpage.

Key characteristics:

Interpreted language: JavaScript code is run directly on the browser without the need for linking to other tools that compile it.

Dynamic typing: Variables can hold different data types which can be useful but dangerous if it’s not written properly.

Prototype-based: This makes JavaScript objects to have exclusive feature of object oriented programming by involving prototypes.

event-driven: JavaScript is useful when it comes to reacting to the end-user inputs and when creating a unique user interface.

Conclusion

Java is a strong language which is designed to solve particular problems while JavaScript is one and only language which solves interaction problems in internet. Java is great for building highly dependable and efficient applications that should deliver high performance and security simultaneously. JavaScript is particularly suited for crafting dynamic web environments and has expanded to the sphere more comprehensively other fields such as transmitting to serve-client-area construction and more.
There could be no outright winner to speak of between the two, but, for that matter, gaining insight into its capabilities and drawbacks helps in selecting appropriate technologies wisely. There are many developers that become proficient in both languages in order to expand one’s skill set and take on more work.

In summary:

Java: Corresponding to the high-performance, reliable and stable enterprise-level applications, Android development and server-side applications.  
JavaScript: Building dynamic web applications where user interactions are well defined, developing interesting user interfaces, and to introduce the server side development with Node.js.
