Though both are programming or scripting languages used by programmers for a variety of tasks, their similarities end with “Java”. One cannot be compared in terms of the other for its uses or strength, as both have their own regard or uses. Also, both run on different plugins. So, here in this article, we have tried to analyse the difference between Java and JavaScript.
The two languages that are being discussed here, are:
- Java
- JavaScript
What is Java?
A programming language that is object-oriented, network centric and multi-platform compatible, Java is utilised as a computing platform and was developed by the Sun Microsystem and released in 1995. This was later taken over by Oracle Corporation. Java can run on virtual machines. Here, the code for Java needs to be compiled.
What is JavaScript?
Not a part of the Java platform, JavaScript is a scripting language that is object based and helps to create web pages that are interactive. This language follows all the rules of the client side programming, so it functions on the web browser without any need for interference or resources from the web server. Developed by Netscape Inc, the code for JavaScript is completely text.
What is the Difference between Java and JavaScript?
Java is an OOP programming language, and it helps to create applications that function in a virtual machine or browser, while JavaScript is an OOP scripting language. Also, the JavaScript code runs on a browser only. Know more about what is the difference between Java and JavaScript from the table below.
Difference between Java and JavaScript
| Java | JavaScript |
| This is OOP or Object-Oriented programming language | This is an object based scripting language |
| A stand-alone language | Not stand-alone, incorporated into HTML program for operation |
| Strongly typed language is used, and data type of variable is decided before declaring or using it | Language utilised is loosely typed, so that the user does not have to worry about the data type before the declaration |
| Code has to be compiled | The code is all text |
| Slightly more complex | Easier in comparison |
| Used to perform complex tasks | Complex tasks cannot be executed |
| Large amount of memory is required | Memory consumption is lesser |
| Programs are saved with “.java” extension | Programs are saved with JavaScript, “.js” extension |
| Stored in the / client host machine under the “Byte” code | Stored in host or client machine as “source” code |
| Compiled on the server before it is executed on the client side | JavaScript is interpreted on the client side |
| Is static and the code once written can be run on any computing platform | Dynamic and is a cross-platform language |
