JavaScript: What is it and why is it so popular in the coding world?

When a user clicks on a content on a webpage and the webpage instantly responds, it’s usually the job of JavaScript. In fact, it is the ultimate coding language, that helps in creating games, websites and apps. Apps like Netflix and Uber, all work flawlessly because of JavaScript. So, if your young coder is interested in designing his own browser-based games or interactive sites it’s time to introduce him to JavaScript. Here is a low-down on this programming language. 

JavaScript: What is it?  
In simple terms, JavaScript is one of the most popular coding languages used by beginners and young coders to communicate a set of instructions to a computer. The specialty of JavaScript is that it uses codes to convert instructions into a interactive and controlled outcome on a computer. Therefore, whenever we come upon any interactive webpage, say an e-commerce website like Amazon, and it is able to work according to our needs, we owe it all to JavaScript. Thus, in web development, if HTML creates the body or main features of a webpage, JavaScript can be called as the director of that operation. JavaScript assesses the user’s need, receives the input and helps in generating the desired output. 

What can a JavaScript do?  
This coding language performs a wide range of functions. Here’s a look into what all it does. 

Creates ideal user experience through the use of alerts and buttons: There are buttons and options on webpages waiting to be used, and when they are finally clicked upon, they lead to visual results. This is especially significant in the world of gaming, e-learning and e-commerce. All these works smoothly, courtesy JavaScript. While an alert sends a message across the screen for the users, helping in the interactive process (web-based coding), buttons on the other hand, assesses user’s inputs and executes interactive content. This way the user too feels involved in the process.  

Makes computer mouses work the way they do: The way the mouse moves, clicks on things and performs a significant computer function, is the working of JavaScript. It involves both computer science (coding) and Physics knowledge. Certain laws of Physics combined with advanced JavaScript allow the mouse to simulate, take commands and perform accordingly, as the user clicks and drags on the webpage.  

Commands image recognition and voice controls: Machine learning is one of the emerging domains in the tech world and the process is all about training computers on how to identify things like voices and faces, images and sounds. JavaScript helps with this training process as it references commands and pass it on from the users to the devices. 

Helps in game responses: JavaScript is responsible for the responses in action-adventure games like Call of Duty and Magic 8-ball. In the former, JavaScript uses loops to help users track enemies and prevent sudden collision. with the help of button clicks. For the latter, JavaScript uses arrays to formulate different string responses to typical “Yes or No” questions.
