What is the Difference Between Java and JavaScript

JavaScript and Java are the two crucial languages used for web development. Java language is utilized to build Android applications, Embedded systems, Websites, and so on, whereas JavaScript is used to create websites combined with HTML and CSS.

This guide will explain Java and JavaScript features and the difference between both languages.

What is Java?

Java is known as the most used object-oriented programming language which can be used for server-based as well as client-based applications. The Java code is reusable and easy to debug. It is written once and runs anywhere. For a beginner, Java is proven to be an easy-to-learn language, as it is based on C/C++. Also, Java is a backend language used to create standalone web and android applications.

Features of Java

Here, we have enlisted the primary features of Java:

    • Java is as simple as C/C++
    • It is a platform-independent language
    • Java uses powerful memory management
    • It is faster compared to other languages

That was a brief introduction to Java. Now, let’s head towards JavaScript and its features!

What is JavaScript?

JavaScript is scripting and interpreted programming language primarily used to design and develop websites. This language can be utilized in combination with CSS and HTML. JavaScript helps to increase the website’s user experience as it updates the content dynamically. It also acts as a back-end and front-end programming language.

Features of JavaScript

The main features of JavaScript are listed below:

    • It is an object-based lightweight scripting language.
    • It can validate users’ input using forms.
    • You can easily integrate JavaScript with other languages.
    • It is easy to test, maintain, and debug.

Before getting started with these languages, you must know their main differences.

We have compared Java and JavaScript based on their differences.

Conclusion

Java and JavaScript are the two most used languages in the industry nowadays. These languages differ as JavaScript is an object-oriented scripting language, whereas Java is an object-oriented programming language. Java is used for GUI, Web, and Android applications, while JavaScript is used for websites only. In this guide, we have mainly discussed JavaScript and JavaScript and compared both languages.
