JavaScript: Quick Description

JavaScript is a scripting language used to create and manage dynamic website content, which means anything that moves, refreshes, or alternates on your screen without requiring you to reload the web page. Features such as:

  • Animated graphics
  • Photo slideshows
  • Auto-complete text suggestions
  • Interactive forms

The best way to understand what JavaScript does is to think about certain web features that you use every day and that you may easily take for granted – such as when your Facebook timeline automatically updates to your screen or Google suggests search terms based on a few characters you started typing. In both cases, JavaScript is enabled.

The results may seem simple, but there is a reason why we teach every aspect of JavaScript to both our Front End Web Developer and Break into Tech Blueprints. Underneath all those beautiful animations and auto-complete – there are some great things happening. This guide will write down exactly how it works and why you use it and how you use it, as well as great ways to learn JavaScript if you feel you need it in your skillset.

What is Javascript?

It is an effective computer programming language. It’s simple and widely used as part of web pages, its users that allow the client-side script to interact with the user and create dynamic pages. A translated programming language with object-focused skills.

  • It is a lightweight, interpreted language
  • Designed to create in-app applications.
  • Compatible with and integrated with Java.
  • Compatible and integrated with HTML.
  • Open and Cross-platform

What is Javascript used for?

We covered this a bit in the introduction, but here’s a quick list of the key features

  • Adding interaction to websites – if you want your website to be animated or more interactive, you’ll need to enable some JavaScripting
  • Improving mobile apps – It is not only for websites, but also used to create mobile apps you have on your phone and tablet
  • Creating web-based games -It is also used for web browser games.
  • With the development of back-end, web– JavaScript is widely used in front of objects, but its variety of functions can also be used in the back-end infrastructure, too.

Advantage of JavaScript:

  • Minimum server connection – You can verify user input before sending the page to the server. This saves server traffic, which means less load on your server.
  • Quick reply for visitors – No need to wait to reload the page to see if they forgot to enter something.
  • Extended interaction – You can create connectors when the user moves over them with the mouse or use them with the keyboard.
  • Rich Communication Tips – You can use JavaScript to install objects such as drag and drop and slides to provide a Rich Interface to your visitors’ help.

Disadvantage of JavaScript:


We cannot treat this as a fully functional programming language. It does not have the following important features –

  • It is next to the client does not allow the reading or writing of files. This is reserved for security reasons.
  • It cannot be used for network applications because no such support is available.
  • It does not have multiple threads or multiprocessor functionality.

Once again, it is a lightweight, translated language that allows you to build links between other HTML pages.

Why Learn Javascript?

JavaScript is a very popular language and is growing in popularity. According to a report from Stack Overflow, It is the most widely used language, for the sixth consecutive year. The popularity increased from 57% in 2013 to 70% in 2017. JavaScript is the most popular language above Java, Python, Ruby, and more.

All browsers come with a source code view feature that lets you read from other people’s live code. Also, JavaScript has the largest and most efficient library code in the world. People in the JavaScript community are very active and supportive of sharing and using each other’s code – JavaScript has a large community in StackOverflow and more than 3,600 JavaScript Meetup groups worldwide.

5. Great tools for correcting learning mistakes

The interactive JavaScript interpreter is built into the browser, allowing you to try and get a quick response, which helps you learn faster.

6. It is the main language of learning the most powerful programming styles

JavaScript comes out of the box with support for event-driven program style, where your code flow is controlled by user events or program events. This system style is very much needed in building user-friendly connections and is a very useful foundation for building systems on the awesome server-side.

JavaScript is accurate when a beginner is just learning the code and a good car to teach students the principles of Computer Science. Once you understand at a deeper level how JavaScript works, you have the power to choose other languages.

Whether you plan to eventually become a previous or final engineer, there is no doubt that JavaScript is an excellent coding language for beginners.
