As the term “Java” in the name of both Java and JavaScript, many people believe that they both are related. Many beginners and non-programmers think that both are interrelated. Well, it is not true. Although, they are similar in a few things. But both are distinct from each other in different aspects.
A programmer should know about the main difference between them. They should know Java vs JavaScript. As both programming languages are powerful and useful in the IT industry.
However, in this blog, we will discuss Java vs JavaScript. We will learn the main difference and similarities between them. Let’s start our learning with an overview of both programming languages.
Java vs JavaScript: Overview
Java and Javascript are used by programmers for a wide variety of activities. The programming language Java is not related to JavaScript at all. Both have a syntax similar to C and are widely used in client-side Web applications.
Let’s learn their definitions.
What is Java?
Java is a programming language. It is multi-platform, object-oriented, and network-centric. Java is the most common programming language. It was first developed by Sun Microsystem in 1995. It is also utilized as a computing platform. Later, it was purchased by Oracle Corporation.
Features of Java
The features of the Java programming language are as follows;
- Create code once that can be run on any computing platform.
- It is created for the development of object-oriented applications.
- It is a multithreaded language with memory management built-in.
- Because of its network-centric design, it supports distributed computing.
What is JavaScript?
JavaScript is a scripting language. It is used for creating pages for dynamic web. It refers to client-side programming principles. That means it operates in the user’s web browser without requiring any resources from the web server. Technologies, Like REST APIs, XML, and others, can also be used with JavaScript. Nowadays, JavaScript includes technologies such as Node.js.
Features of JavaScript
Following are the features of JavaScript;
- JS is a platform-independent language.
- It is commonly used on both the client and server sides.
- Workflow for Good Testing
- It is simple to get started with and learn.
- Dependencies that have been added
Java vs JavaScript: Similarities
Although they are different. But there are certain top-level similarities. Particularly when comparing Java and JavaScript in the context of web app development. Some of the similarities between both, Java and JavaScript are as follows;
Object-Oriented Programming
In both languages, the developer has to code objects and their connections with respect to one another. As a result, both languages have access to inheritance, encapsulation, and polymorphism mechanisms.
Front-End Development
Both languages have applications in front-end development. JavaScript can be directly inserted into HTML as a framework or library. Whereas, Java can be utilized as a Java applet.
Back-end Development
On the server, both languages are supported. Back-end technologies like Apache, JBoss, and WebSphere have long relied on Java. Node.js has developed into a platform for JavaScript-based servers.
Java vs JavaScript: Main Difference
Object-Oriented Programming Languages
Java:
This is an object-oriented programming language. It uses objects to complete operations depending on the relationships between them.
JavaScript:
JS is an object-oriented scripting language that makes use of Java objects.
Types of Languages
Java:
Java is Static.
JavaScript:
JS is Dynamic.
Types of Object
Java:
Java objects are based on classes. So, you can not write a program in the language without creating a class.
JavaScript:
Prototypes are used to create objects in JavaScript.
Extension
Java:
The file extension of Java is “.Java”.
JavaScript:
“.js” is a file extension of JavaScript.
Syntax
Java:
The syntax of the Java programming language is similar to C/C++. Classes and objects will be used in the Java program.
JavaScript:
The syntax of the JavaScript language is similar to the C programming language. However, name rules are identical to those of the Java programming language.
Mobile Applications
Java:
Older mobile applications are frequently built in Java. And the systems like Android and Symbian are also built with the help of Java.
JavaScript:
Mobile applications can be improved by using JavaScript. But, there are some restrictions, such as the requirement to use third-party tools. For example, the phone gap to change to the original code so that a mobile OS/platform can run.
Running Platform
Java: Java applications and programs operate in a Java virtual machine. It requires the JRE and JDK to be installed on a system.
JavaScript: JavaScript programs execute on a web browser without the need for any initial configuration.
Learning Curve
Java:
Java has excellent documentation, online forums, online sources, and locations where anyone can quickly learn. You can study Java if you want to do programming and develop applications.
JavaScript:
It also has excellent documentation, online forums, online sources, and sites where anyone can easily learn JavaScript. We can learn JavaScript if we wish to develop web applications and websites.
Conclusions
To conclude, now you are aware of Java vs JavaScript. We have also discussed the similarities between them. We have learned the different features of Java and JavaScript. One is used for application and back-end programs. Whereas, the other one is used for creating applications for the web.
So, in the end, I hope now you have a good understanding of Java vs JavaScript. If you become good at both languages. Then there are a lot of career opportunities you have.
FAQs
1. What is better, Java or Javascript?
Answer:
Java is extensive, fast, and supports a better app development process. JavaScript is lighter and better for interactive apps. So, you can choose between both according to your needs.
2. Is Java the same as JavaScript?
Answer:
Each and every language needs different plug-ins. JavaScript’s code only runs on a browser. Whereas, Java creates applications that run in a virtual machine and browser.
