Java Vs Javascript Difference Between Them

Java vs JavaScript

What is Java?

Java is a multi-platform, object-oriented, and network-centric, programming language. It is among the most used programming language. It also used as a computing platform, and it was first released by Sun Microsystem in 1995. It was later acquired by Oracle Corporation.

What is JavaScript?

JavaScript is a scripting language that helps you create interactive web pages. It follows the rules of client-side programming, so it runs in the user’s web browser without the need for any resources form the web server. You can also use JavaScript with other technologies like REST APIs, XML, and more. Nowadays JavaScript also using technologies like Node js.

Java vs JavaScript – Difference Between Them

A major difference Java and JavaScript is that Java is compiled and interpreted language while JavaScript code is directly executed by the browser

Features of Java

Here are the important features of Java.

Write code once and run it on almost any computing platform It is designed for building object-oriented applications. It is a multithreaded language with automatic memory management Facilitates distributed computing as its network-centric

Features of JavaScript

Here are important features of Java-script:

It’s a cross-platform language It’s widely used for client-side and server-side Strong Testing Workflow It’s easy to learn and to start coding with Added dependencies

Application of Java

Here, are important applications of Java language: To develop:

Android Apps Enterprise Software Scientific Computing Applications Big Data Analytics Java Programming of Hardware devices Used for Server-Side Technologies like Apache, JBoss, GlassFish, etc.

Application of JavaScript

Here, are some important applications of JavaScript:

Dynamic Single-Page Applications (SPAs) Front-End technologies like jQuery, AngularJS, Ember.js, ReactJS are based on Java Script Server-Side technologies like Node.js, Express.js, MongoDB are based on Java Script. Mobile App Development using PhoneGap, React Native, etc.

Detailed documentation is available. A large pool of skilled developers available Huge array of 3rd party libraries It allows you to form standard programs and reusable code. It is a multi-threaded environment that allows you to perform many tasks at the same time in a program. Excellent performance Easy to navigate libraries

Advantages of JavaScript

Here, are pros/benefits of using JavaScript

It is an open-source project with Microsoft’s patronage Specially designed tool for small scripts Supports classes, interfaces, & modules. Compiled JavaScript runs in any browser Allows cross-compilation You can extend JavaScript for writing large apps You can use JavaScript to store and retrieve information on the user’s computer Immediate feedback to the visitors It allows you to create interfaces that react when the user hovers using mouse.

Disadvantages of Java

Here, are cons/drawback of using Java language

JIT compiler makes the program comparatively slow. Java has high memory and processing requirements. Therefore, hardware cost increases. It does not provide support for low-level programming constructs like pointers. You don’t have any control over garbage collection as Java does not offer functions like delete(), free().

Disadvantages of JavaScript

Here, are drawbacks/cons of using JavaScript

Client-side JavaScript does not allow the reading or writing of files. It has been kept for security reasons. JavaScript can’t be used for networking applications because there is not much support available. JavaScript doesn’t have any multithreading or multiprocessor features.
