Java vs JavaScript: What’s the Difference?

I often get asked that is JavaScript similar to Java. Or vice versa. The things are that Java was solely intended for implementing the cross-platform execution of applications. Meaning that applications written in Java can be executed on any machine or on any platform, Windows, Linux, Unix, Mac. Java does not have complex requirements to run.

 

It just requires the Java Development Kit for executing Java programs. The source code is first converted to byte code by the Java Compiler and then from byte code to the machine-readable code in the second stage of execution.

 

JavaScript was created with the sole purpose of adding interactivity and validation for online forms. JavaScript can be executed solely on a browser and is used for creating Front end applications. There are many frameworks that exist for JavaScript that provides a different kind of functionality to the programs.

Java

JavaScript

Java is an Object-Oriented Programming Language developed by James Gosling of Sun Microsystems that was later acquired by Oracle.

JavaScript is a Client-Side Scripting language created by Netscape and was originally known as LiveScript.

This is the standalone language that is executed by the Java Virtual Machine (JVM) that needs to be compiled into Byte-Code and has the file extension “.java”

JavaScript’s code must be placed inside an HTML document and executed by a web browser such as Google Chrome or Mozilla Firefox and has the “.js” file extension

Java works on class-based objects and you will not be able to program in Java without creating a class.

JavaScript works by using the Prototype-based concept

To execute Java programs, you will require the entire Java Development Kit (JDK)

To write JavaScript programs you only require a text editor such as Notepad, Notepad++ or WordPad.

Java supports the static type of checking for programs

JavaScript supports the dynamic type of checking for programs

The full source code is hidden as the code is compiled into an unreadable byte-coding type.

The source code can be read by any person as it is written in plain text.

Java is developed by keeping the “security of codes” as the primary motive that can be achieved through JVM.

JavaScript is less secure and you have to constantly make efforts to secure its coding from cross-site scripting, etc

Java supports class concurrency that allows to  work with many threads and help maintain parallel concurrency in coding

Concurrency is based  on the queue system “event loop” that is able to support and provide features as async/await in coding

Java is a compiled language

JavaScript is an interpreted language

Java is mainly used for backend programming

JavaScript is mainly used for FrontEnd programming

Java can either be executed by a JVM or by a browser

JavaScript is solely executed in the browser.

Java offers strong security features compared to JavaScript

JavaScript needs more effort to provide enhanced security.

The syntax is similar to C++

The syntax is similar to C

Java can be used for creating various kinds of apps.

JavaScript is used mainly for Web Apps

Conclusion:

So now you know that Java is used for general programming purposes and JavaScript is used for Front end programming purposes. We hope you have gained some insight into what Java and JavaScript is all about.

What is the difference between Java and JavaScript(Java vs JavaScript)

200 people rated 05/05

It often happens that programmers and users get confused between Java and JavaScript. Javascript is a lightweight programming language while Java is a class-based object-oriented programming language.

 

As both Java and JavaScript refers to the same OOP language and shares the same control structures and operators. But when you’ll learn them individually you’ll get to know they are completely different from each other. Despite these similarities in syntax, they differ in various aspects.

 

Java

 

Java is a popular computer software programming language invented by James Gosling and developed by Sun Microsystems. It is a general-purpose high-level programming language created in the year 1995. Java is an object-oriented language designed to give you the feel of C++. However, it is much simpler and easy to use than C++.

 

Originally Java was named as OAK but later it changed into Java. With its virtual machine platform, it allows you to create compiled programs that run on nearly every platform.

 

Use

  • Java with abundant features and its advantages is used to create applications that may run on a single computer.
  • It can also be distributed among servers and clients in a network.
  • Java can be used in a wide variety of computing platforms to enterprise servers and supercomputers.
  • It can be used to make mobile applications, web and desktop applications, games and much more.

JavaScript

 

JavaScript is a lightweight programming language of HTML and Web used to make web pages interactive. As a multi-paradigm language, it supports event-driven, functional, imperative and programming styles.

 

JavaScript web page implementations allow a client-side script to interact with the user and make dynamic pages. It was first known as LiveScript but later Netscape changed its name to JavaScript.

 

Differences Between Java and JavaScript

 

It’s a very common perception thinking both Java and JavaScript are the same. But the truth is there is nothing common between them except their name Java. Both are completely different and have nothing to do with each other. Their working, functionality, and capabilities all are very different.

 

Here’s a list of key differences between Java and JavaScript as programming languages. Java vs JavaScript

 

The-Difference-Between-Java-and-Java

As Java has so many important features it is the most commonly used programming language. Whereas JavaScript, on the other hand, possesses some features that Java lacks. JavaScript does not require any compiler or editor it is considered as the easiest language to learn.

 

Thus both Java and JavaScript carrying different features are equally important in their areas of requirement.

Conclusion

Both Java and JavaScript(Java vs JavaScript) are different languages and have no similarities except the syntactic resemblance. After going through the above comparison between Java and JavaScript you can very well know about their differences and similarities. Java is a general-purpose language used for developing desktop or mobile or web-based applications.

 

On the contrary, JavaScript is a client-side scripting language used for designing the behavior and interactivity for web-based applications. However, both are very popular and effective while creating interaction between the user and the web page.

 

To develop your own web or mobile app you should know the complete difference between both Java and JavaScript. The above-given difference will help you learn in-detailed differences between both of them.
