JavaScript Basics

The What and Why of JavaScript

JavaScript is a programming language used to make interactive web pages. It runs in the browser, on your visitor’s computer. When a user requests an HTML page containing JavaScript, the script is sent to the browser. It’s then up to the browser to do something with it.

JavaScript allows you to write fast and efficient web pages to create a desktop-like experience for your website users. JavaScript will process and run code on the client. This allows the page do many things before making an expensive request back to the server.

Common usages include:

  • Allow users to interact with forms. This includes validate rules and data.
  • Prompt and alert users for certain events (e.x. incorrect password characters)
  • Auto complete a drop down control to help the user filter entries
  • Present smart layout by dynamically positioning elements on the screen
  • Animate elements on a page
  • Tons more…

JavaScript is now mainstream. Companies and developers use JavaScript to create highly interactive web applications to meet the demands and expectations of modern day users.

More reasons to use JavaScript


  • JavaScript models the English language, making it intuitive to write and maintain code
  • Many tools exist to extend JavaScript capabilities
  • Many tools exist to write code faster, and test and debug code better
  • JavaScript is object-oriented, which is popular and well-understood by developers
  • JavaScript is a prototyping language, allowing you to define new objects real-time
  • There are many libraries and frameworks to manipulate and adjust web pages
  • JavaScript is universally supported, making your web application work as intended in all modern browsers

Why JavaScript for my projects?

We covered some basics. Some practical applications for using JavaScript include:

  • Customize the appearance of a page, specific for a user
  • Examine and change HTML based on a certain scenario
  • Support drag and drop of images to upload to your site
  • Create simple, or complex, animations to show off your product
  • Make your website easy to navigate: show tooltips, expand sitemaps, swap images, provide helpful suggestions, display a thank you message
  • Write games for an entire community

JavaScript Basics

Why write JavaScript code from scratch? Same for testing and debugging. Here’s some popular frameworks to save you from reinventing the wheel.


React is an open-source JavaScript framework for building user interfaces. Its main goal is to be fast, simple and scalable. React will efficiently update and render just the right components when your data changes. It’s used by Netflix, Imgur, Bleacher Report, Feedly, Airbnb, SeatGeek, HelloSign, Walmart, and others.

  • Declarative views make your code more predictable and easier to debug
  • Build encapsulated components to manage their own state, then…
  • Compose and organize your components to make complex user interfaces


Building a complex web front-end application? Want a single modular framework to handle everything? AngularJS is a popular enterprise framework to build and maintain complex websites. It’s good enough for Domino’s Pizza, iTunes Connect, PayPal, Google and a bunch more. Bet it’ll do the job for you, too.

AngularJS is a Model-View-Controller (MVC) type framework:

  • Create two-way data binding between models and views, for automatic updates when data changes
  • Build reusable view components to save time
  • Easily enable backend and frontend servers to stay synchronized


Vue is a lightweight alternative to AngularJS. Vue is a library focused on view layer only. It will keep what you see on the screen synchronized with the data model. Use this framework to create simple and flexible views without the overhead of a larger framework.

  • Leverage your existing HTML skills
  • Extend HTML’s syntax to clearly and succinctly describe your components
  • Reduce code you write, while AngularJS dynamically injects code for you

There’s more, plenty.

The frameworks above represent some of our favorites. Others to consider include JQuery, Ember, Redux, MobX, KnockoutJS, BackboneJS, DurandalJS and plenty more.

You now know something about JavaScript and are eager to use JavaScript for your next project. Cool. Time to...

Hire a JavaScript developer

JavaScript is everywhere. So are JavaScript developers. This can make it difficult to find and sift through the great ones. Check out our Ultimate Guide of How to Hire for Web Development. Apply some of the same concepts for hiring your next JavaScript developer. Same goes for finding them, too.

Following are things to consider specifically for JavaScript development.

Skills and qualifications

Find out about these for your candidate developer (and build up this list for your needs):

  • Why include ‘use strict’ at the beginning of a JavaScript source file?
  • What is and how can you reliably test if a value is equal to ‘NaN’?
  • What are two programming paradigms important for JavaScript?
  • What is functional programming?
  • What is the difference between classical inheritance and prototypal inheritance?
  • What are the pros and cons of functional programming vs object-oriented programming?
  • What is the difference between undefined and not defined in JavaScript?

Obviously, these are just a few questions to learn more about your candidate developer.
