What Is The Difference Between Java and JavaScript? Detailed Comparison
Both Java and JavaScript are popular programming languages with different purposes, uses, features, and limitations. You cannot choose any programming language before understanding the proper requirements and needs of your project.
The main difference between Java and JavaScript is their usage. Java is used to build enterprise-level applications, while JavaScript is used in web development. Many differences like that are also there making both of these languages different from each other. And yes, that’s what we are going to discuss today.
In this article, we’ll share everything about these two programming languages and discuss some comparison points differentiating between them. To know, stay with this page and be good to go.
Let’s dive right into this.
What is Java Programming Language?
Java is an object-oriented programming language that is used to make various applications including mobile applications, software applications, desktop applications, GUI applications, game development, and enterprise-level systems. Java offers various frameworks and libraries used to enhance the development procedure and functionalities.
Pay attention – Java was developed in the mid-1990s by James Gosling and his team at Sun Microsystems and later acquired by Oracle Organization.
Talking about the trending features of Java making it a priority choice among developers worldwide include its WORA Philosophy. It stands for “write once, run anywhere.” Meanwhile, Java developers can build codes once and can run them anywhere on any platform or operating system whether it's Windows, macOS, or Linux.
Java offers great flexibility, scalability, and cross-platform compatibility. Java programs are compiled into intermediate bytecodes and executed by JVM. That’s how Java softwares runs on any device. In fact, JVM promotes bytecode verification and ensures no malicious attacks.
Java is also known by the Android environment and is declared as the official language for Android application development. It provides you with various pre-made frameworks and libraries, pre-build classes and methods, and much more. Along with such a feature list, it also has some limitations. For example, syntax verbose and performance issues are observed because of extra execution steps by JVM.
What is JavaScript Programming Language?
JavaScript is a widely used programming language for web development projects, such as web applications. The reason behind its wide use among developers worldwide is its core ability to be directly embedded into HTML pages. Web developers can enhance the interactivity and functionality of web applications and ensure dynamic user experiences by using JavaScript language.
This language was developed back in 1995 by Brendan Eich at Netscape Communications Corporation. The language was named “Mocha” before officially released as “JavaScript.” There’s an interesting historical background of this language: Brendan Eich developed this language only in 10 days.
Talking about some of the great features of JavaScript, the language shows great compatibility with Node.js and can be utilized on the server side as well. That’s how you can use JavaScript for both server-side and client-side development and promote great functionality.
Similar to Java, you can also enjoy the vast collection of libraries and frameworks with JavaScript. Such as Vue.js, React and Angular etc. Along with such appreciating benefits, this language also has some limitations. You might face errors handling complex computations and code execution.
Java vs. JavaScript: What’s the Difference?
Java and JavaScript are two different programming languages as explained above. They are different from each other at various points. For your better navigation, we have explained almost all the points they are different in.
Explore them and see how they are different from each other in various features.
Purpose of These Languages
Java is an object-oriented and general-purpose programming language that can be used in various ways. Meanwhile, you can build web applications, Android mobile applications, and even enterprise-level systems with it. On the other hand, JavaScript is a scripting language used for web development, and to enhance UI/UX In web browsers.
Platform Type
JavaScript is primarily used only in web browsers and runs on the client side for better web page interactivity. On the other hand, Java programming language is platform-independent and uses JVM for its code execution on various devices. Java Virtual Machine (JVM) promotes a “write once, run anywhere” philosophy due to which single Java codes can be deployed anywhere on any platform without modification.
Execution Environment
The execution process for both of these languages is different. For Java, applications are compiled into bytecode by the Java Virtual Machine and then executed. This allows Java applications to run anywhere on any platform, operating system, or device. Interestingly, it can also be used for server-side and client-side programming at the same moment.
In contrast, JavaScript is primarily used for client-side scripting and is an interpreted language that is executed by web browsers. The execution of this language is complex because you need to promote the advent of Node.js with it to use for server-side development also.
Different in Typing
Java and JavaScript are also different in Typing. Java is a statically typed language while JavaScript is a dynamically typed language. Meanwhile, developers need to explicitly declare the data type of a variable in Java while there’s no need in JavaScript. In Java, variable types cannot be changed during the runtime. While JavaScript allows variables to change types during the runtime.
Frameworks and Libraries
Java and JavaScript both have a vast ecosystem of libraries and frameworks, but the purposes for libraries and frameworks by both of these languages are different. For example, frameworks in Java are used to make efficient enterprise-level applications, while the frameworks in JavaScript focus on client-side and server-side development.
Popular frameworks by Java include Apache Struts, Spring, and Hibernate. In contrast, JavaScript offers popular frameworks such as Node.js, React, and Angular.
Programming Type
Java strictly supports object-oriented programming and clearly emphasizes classes and objects. On the other hand, JavaScript supports both; object-oriented and prototype-based programming. This is how it supports object creation without classes.
This is how both Java and JavaScript programming languages are different from each other. Now, let’s discuss which programming language is right to choose for your project.
Java vs. JavaScript: What to Choose For Your Project?
Java and JavaScript both programming languages have their benefits, uses, purpose, and features. Java allows you to efficiently make enterprise-level applications, while JavaScript helps you enhance web development project procedures.
Using Java, you can focus on developing large-scale projects, Android applications, games development and backend systems. In contrast, you can focus on web development, web applications development, interactivity and functionality of websites on the client side with JavaScript.
The bottom line is, that you can only choose between Java and JavaScript when you properly understand your project requirements. If you are developing an Android application, obviously Java is the right choice for you. On the other hand, if you’re making a website, JavaScript is the appropriate choice. So, first, understand your project requirements and choose the ideal language between both of them accordingly.
