What's the Difference Between Java and JavaScript?

Java and JavaScript are two of the most popular programming languages today. We use these languages to develop software for websites, web browsers, desktop applications, mobile devices, and much more. But each language has its own advantages over the other.

In this article, we will explore the main differences between Java and JavaScript from a technical point of view by comparing their features and capabilities. So what is the difference between Java and JavaScript? Which should you use? Keep reading to find out!

What is Java?

Java is a programming language that was invented in 1991 by Sun Microsystems. It got widespread adoption when the Android operating system was developed. We use Java to create applications for a variety of different platforms, like computers, mobile devices, and embedded devices.

Here are some important key points about Java:

Java supports both server-side and client-side programming.
It is an open-source language and is free to use.
The language is object-oriented and is based on the C and C++ programming languages.
Java is an imperative programming language. This means that it uses instructions to tell the computer what to do.
It is designed to run on all computer platforms, from desktop computers to embedded devices.
The language has built-in support for object-oriented programming, which lets you organize your code by grouping related functions together.

What is JavaScript?

JavaScript is a scripting language that was invented in 1995 by Netscape. It is now widely used across many industries to build web applications. JavaScript has become an industry standard, as it is supported by almost every major browser vendor.

Here are some important key points about JavaScript:

JavaScript programming language is an imperative programming language. This means that it uses instructions to tell the computer what to do.
It is designed to run on all computer platforms, from desktop computers to embedded devices.
The language has built-in support for object-oriented programming, which lets you organize your code by grouping related functions together.
Javascript runs on most browsers, including the latest versions of Chrome, Firefox, Edge, Safari, and Opera.
When you write Javascript code, it executes almost instantly, so it’s ideal for use in web applications.

Key Differences Between Java and JavaScript

First, Java is a compiled language while JavaScript is an interpreted language. This means that Java code is converted into machine code before it is executed, while JavaScript code is executed directly by the browser.

Secondly, Java is a statically typed language while JavaScript is a dynamically typed language. This means that Java requires you to declare the type of data a variable will hold before you can use it, while in JavaScript you can simply use the data without declaring its type.

Third, Java is a platform-independent language while JavaScript is a platform-dependent language. This means that Java code can be run on a variety of different platforms, while JavaScript code can only be run on browsers and server-side through the JavaScript engine.

Finally, JavaScript has a larger community of developers than Java does. This means that there are more resources available to help you learn and work with JavaScript, whereas the JavaScript community is smaller and may not have as much support available.

Conclusion

Java and JavaScript are two of the most popular languages used in the software industry. They both have unique features that make them stand out from the crowd. However, they both support various programming paradigms and can be used in different areas of business and technology.

Which one you should use will depend on your specific project and your team’s preferences. As with any other programming language, you’ll find that one provides more utility than the other. In the end, it will come down to your own experience and expertise.

Java is a powerful general-purpose programming language that has stood the test of time. It runs on any platform and can be used to develop Android apps, among other things.

Whereas, JavaScript is a lightweight language that has become an industry standard for building web applications. It is easy to learn and supports almost every browser, making it an attractive choice for web development.
