Java vs. JavaScript: Unveiling the Key Distinctions
Java and JavaScript are among the popular and widely used programming languages. Due to the similar sounding term, they are often confused and lead to a common question: ‘Are Java and JavaScript the same?’. However, the fact is that they are distinctly different in various aspects, starting with their purpose, features, and more. So, let’s explore both languages, ie, Java vs JavaScript and understand the key difference between Java and JavaScript.
What is Java?
Java is an object-oriented programming language and software platform that can run on multiple platforms. It is used to create applications that can be adapted to any device, including notebook computers, mobile devices, gaming consoles, medical devices and many others. It was initially launched by Sun Microsystems in 1995 and is currently owned by Oracle.
Key Features of Java
Java is enriched with features and libraries that make it one of the most competitive programming languages available today. Here are some of the key features:
Server-side scripting
Java is frequently used for server-side scripting in desktop and mobile apps that are accessible over the web.
Lightweight and Flexible
Java programs are simpler to understand and contain fewer low-level features since the JVM and compiler automatically handle such functions. Java is made lighter and more versatile as a result.
Event Driven
Java is an event-driven programming language, which implies that a series of events define how the program will be executed. Each event handler typically has a specific object or control attached to it, and it can call other programme parts (events) as and when necessary.
Dynamic Typing
Java is statically-typed which means that the variables are declared before and are assigned values.
What is Javascript?
JavaScript is a programming language used to produce or update information on the web in a dynamic way.
Key Features
Purpose
The main purpose of JavaScript is to develop interactive and dynamic web pages. It is the main reason behind creating a user experience on the web.
Execution Environment
JavaScript is most often executed on web pages inside the browser. However, it can also be run server-side.
Typing
JavaScript is that it can be dynamically typed, which means the variable types are determined at runtime.
Development Domain
JavaScript is a versatile programming language that spans a wide range of development areas. For example, single-page applications (SPAs), progressive web apps (PWAs), browser extensions, mobile applications and even automated repetitive actions.
What is the difference between Java and JavaScript?
Let’s explore the key difference between Java vs JavaScript.
Java | JavaScript |
It is an object-oriented programming language | It is a scripting language |
It is a standalone language and can be executed without being integrated. | It needs to be integrated with HTML code to be executed. |
Objects of Java are class-based | JavaScript Objects are prototype-based. |
Java is mainly used for backend | Javascript is used for the frontend and backend both. |
Java programs do not require a web browser to run. | JavaScript requires a web browser to run. |
Java program has the file extension “.Java” | JavaScript file has the file extension “.js” |
Java and JavaScript differences are apparent from the definition and distinguishing characteristics listed above. Knowledge of each is critical since they each play important roles in the world of programming and software development.
