JavaScript vs Java

Many programmers mistakenly believe that JavaScript and Java are the same thing. In reality, JavaScript and Java have little in common. During the early days of Netscape, the histories of these two famous programming languages did cross for a brief period of time. Nowadays, Java is the second most popular programming language and it is very famous among developers. But each is a programming language with its own set of advantages and disadvantages. So that programmers use both Java and JavaScript languages for different tasks. Now let’s see small introduction about JavaScript and Java.

JavaScript

Brendan Eich, a developer at Netscape, Inc., was able to develop a programming language that could tell the machine how to communicate with the user after receiving user feedback. This language was dubbed “Livescript,” and it was directly incorporated into Navigator. Later, Netscape renamed their language as “JavaScript.” JavaScript is a text-based programming language that can be used on both the client and the server. It is high-level, lightweight and flexible programming language. JavaScript conforms to the ECMAScript specification. This programming language supports event-driving, functional and imperative programming styles.

Java

James Gosling is the creator of the Java programming language. In 1996, Sun Microsystems released the first public implementation as Java. Java is a class-based programming language that can be used on server side for most back-end development projects. It is high-level, fast, secure and object- oriented programming language. Java is commonly used for mobile development, AI, web development etc.

Most Important Differences:

JavaScript compiling and processing speed faster than Java programming language.

JavaScript is a weakly typed language while Java is a strongly typed language.

JavaScript is dynamic and Java is static.

In JavaScript use “.js” as file extension. Java use “.java” as file extension.

JavaScript is dynamic and data types not declared. Java is static and data types must be declared.

JavaScript code used to run only in browser and Java applications can run in any browser or virtual machine.

Advantages and Disadvantages of JavaScript:

Advantages:

• Ability to support all modern browsers.
• Very fast
• Platform independent.
• Easy to learn.
• Can help run multiple tasks at once.

Disadvantages:

• Some times may be difficult to develop large applications.
• Client-Side security.
• Lack of debugging facilities.
• A single error can stop entire JavaScript code.

Advantages and Disadvantages of Java:

Advantages:

• Easy to learn, write, compile, debug and use.
• More secure than JavaScript.
• Platform independent.
• Multithreaded programming language.
• Memory is divided into two parts. so that, it helps to restore and keep information easily.

Disadvantages:

• Java programming language bit costly than others.
• It provide garbage collection automatically.
• Some times it perform slower than other programming languages.
• Consumes more memory.
