Java vs JavaScript

Java and JavaScript are programming languages. Java is an object oriented programming language whereas JavaScript is more of a scripting language. Both can be used to make web pages more interactive. However, Java is also used to develop server side applications and standalone programming.

Java

Java is an object oriented programming language. In early 1990s, Sun Microsystems developed the Java language. Initially, it was designed to make small programs for the web browser called applets. But later on, Java was used to create applications based on e-commerce.

There are five main features of Java language:

• Provides more flexibility to develop software applications because of object oriented approach.

• Easy to use as it combines the best properties of other programming languages.

• Allows code written in Java to run on different platforms or Java code is independent of platform.

• The code from the remote source can be executed securely.

• Built-in support for computer networks.

Java also supports automated memory management model that allows developers to get rid of the time consuming method called manual memory management. Programmers can easily do this by implementing automatic garbage collection. But according to some people, Java is slow as well as consumes more memory than other programming languages such as C++.

JavaScript

JavaScript is also a programming language which is used to make web pages more dynamic as well as interactive. Constant downloads from the server are not required in case of JavaScript as it runs on the user’s computer. JavaScript is different from the Java programming language.

Most modern day web browsers have built-in JavaScript. However, JavaScript based web pages can run only if JavaScript is enabled on the web browser and the browser supports it. JavaScript is enabled in most browsers by default.

No special program is required in order to write code in JavaScript as it is an interpreted language. You can use any text editor such as Notepad in order to write JavaScript code. You can also use other text editor that colorizes the different codes making it easier to detect any error.

JavaScript is different from HTML because JavaScript is used to create more dynamic web pages while HTML is a markup language that is used to create static content on the web page.

You can insert the JavaScript code in a HTML file by using the <script> tag. But if you want to use the script in different pages of the website then you can save the scripts in different files with .js extension.
