What is JavaScript?

JavaScript is used along with HTML and CSS for front-end web development. These three together make the front end of the website visually appealing HTML and CSS alone cannot add interactivity and dynamic changes as it lacks a programming mechanism. This is where JavaScript comes to play a crucial role in implementing the programming concept such as adding functionalities, interactivity, and validation to your webpage. JavaScript, HTML, and CSS are the “3 musketeers” without these “Three Trios”, webpages will appear dull and sluggish

Let’s Understand the Concept of JavaScript with a Brief Example

Let’s say you want to show a popup message whenever the user clicks on a signup button. To do so, you need JavaScript because HTML and CSS don’t have programming properties. Thus, JavaScript allows web developers to create a function and call it. In this case, developers can create a function called the “OnClick” property and call it, whenever the user clicks on the signup button. Apart from this, JavaScript also helps to conduct the validation for email addresses, passwords, etc. Therefore, JavaScript is an integral part of web development. The following are some of the basic use cases of JavaScript: 

  • Slideshows 
  • Interactive maps 
  • Pop-up windows 
  • Web games 
  • Form validation

Is Java and JavaScript Same?

No! Java is a standalone language that supports Object-Oriented features and runs on JVM machines. JavaScript, on the other hand, is a lightweight scripting language, which doesn’t support Object-Oriented features. It plays a pivotal role in adding interactivity and elegance to your HTML code.  

Most importantly, JavaScript follows the principle of prototype. The second major difference between these two languages is that Java runs its code on a JDK kit and JavaScript relies on web browsers to run its code.

JavaScript is not limited to the end-users nowadays; businesses can do so much more with JavaScript. A powerful React.js is a JavaScript library that helps to quickly build a GUI for apps. Similarly, Redux is another JavaScript framework that aids in testing applications across various web browsers. When JavaScript is combined with Node.js these both form a “Powerful Duo” for the backend development.  

The following are some of the domains where businesses can use JavaScript for improvements:

  • Web Applications: The one important area where businesses need to give more focus is browsers. Day by day we are noticing notable changes in browsers. As the browser continues to evolve JavaScript demand keeps on increasing for building reliable web apps. A prominent example is Google Maps. Google uses JavaScript to create a map for users. This map provides a convenient way to find places, locations, restaurants near you, directions to the desired destinations, and many more.
  • Mobile Apps: JavaScript offers frameworks to make progressive mobile apps. One of the popular frameworks for mobile app development is React Native. Businesses can create some impressive apps that can work on all operating systems using React Native. Apart from React Native, businesses can also use Angular, and PhoneGap for mobile app development. A prime example of this scenario is Spotify, a popular music streaming app that uses JavaScript for mobile app development.
  • Simple Web Games: Businesses can improve the engagement and interactivity of websites by creating web games. Through JavaScript, businesses can create simple web games such as HexGL (a racing game) and Mk.Js (which is similar to Mortal Kombat and Tekken). Though it cannot create complicated games like the C# Unity engine, these simple games are enough to captivate users with their addictive nature.
  • Server Applications: Node.js helps JavaScript to manage HTTP requests and offers the environment to operate on servers. This is one of the bonus points for businesses that use JavaScript. LinkedIn is one of the notable names that use JavaScript with Node.js for seamless data sharing.
  • Deep Learning: deeplearn.js, ConvNetJS, and brain.jsto, are three libraries to train neural networks in the browsers. JavaScript is a popular scripting language; thus, it can be used to research and implement deep learning techniques.

C# vs JavaScript

The table highlights the difference between these two powerful languages.

C# JavaScript
It runs under the .NET framework; an ideal choice for creating standalone web applications/desktop applications and servers It runs on browsers
C#’s newer version supports autocomplete and dynamic typing to catch errors that speed up the development It is more verbose and tedious with no additional support for faster code execution
It follows the principles of Object-Oriented Programming (OOP); where classes, objects, and inheritances are key features JavaScript also supports the OOP concept.  But uses “Object” in a dynamic manner
C# is not platform independent JavaScript is platform-independent; web developers can write a script once and run it on multiple web browsers
C# code is translated into machine code by the compiler before its execution JavaScript is an interpreted language; its code is executed line-by-line. Thus, it doesn’t generate syntactic errors during runtime
Automatic error detection contributes to code consistency and flexibility Less stable than C#
Developers need to declare the data types and return type before writing the main program It is more flexible; variables can change dynamically during runtime
C# is in demand today, but one needs to understand REST API ASP.NET MVC, ASP.NET Web API, Unity, Xamarin, WPF, Windows Forms, .NET Core, Mono, and all major SDK cloud platforms JavaScript’s wide use cases across various domains makes it more popular than C#
