Use Case of JavaScript

What is JavaScript?

JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user. Common examples of JavaScript that you might use every day include the search box on Amazon, a news recap video embedded on The New York Times, or refreshing your Twitter feed.

Why to use JavaScript over other programming languages?

Aside from the unlimited possibilities, there are many reasons for web developers to use JavaScript over other programming languages:

  • JavaScript is the most popular language
  • There’s a low threshold to get started
  • It’s a fun language to learn

Applications of JavaScript?

Every type of software uses JavaScript, including the server code (Node.js), productivity apps, 3D games, robots, IOT devices.

Importance of JavaScript in Web Designing

There are different web designing and practical uses of JavaScript:

1. Improvement in Web Interface

In these days, what we are doing with JavaScript is we enhance the old, tired and true web interface — clicking links, entering information and sending off, etc — to be more responsive to the end-user.

2. Word Suggestion in Search Box

A search box can give you suggested results when you type, based on what has been entered so far.

3. Instant Update of Information

Information that changes constantly can load periodically without the need for user interactions.

4. Loading Information Only When User Choose

Information that is nice to have and runs the risk of being redundant to some users can be loaded when and if the user chooses to access it.

5. Fixing Layout Issues

It can find the position and area of the element on the particular page and the dimensions of the browser window. By implementing this information you can stop overlapping elements and other similar issues.

6. Enhancing HTML Interface

JavaScript can enhance the interfaces that HTML gives us. While it’s nice to have a text input box, you might want to have a combo box allowing you to choose from a list to preset values or enter your own. You can enhance a normal input box to do that, using JavaScript.

7. Animation of Page Elements

JavaScript helps to animate elements on a page to show and hide information or highlight specific sections of a page and make it more usable and richer user experience.

🎯Candy Crush…

🎀Over the last decade, JavaScript has become, by far, the most popular language for mobile application development. This happened because of early adoption by tech giants like Facebook and Netflix and by the JavaScript development outsourcing firms who help these businesses scale their development capabilities.
