What Is JavaScript?
In some ways, JavaScript is the programming language that made the World Wide Web what it is today.
While the World Wide Web was created in 1989 by a British scientist by the name of Tim Berners-Lee, its advent had little to do with how it is used today.
Lee, who worked at a research organization called CERN, simply wanted to share information with other scientists like himself. And after developing the first web browser in 1990, this tool, so to speak, was in fact rolled out to other research institutions.
The Mosaic browser, whose creators later founded Netscape, was the first web browser with a graphic user interface, marketing itself to non-technical consumers who played a large role in the World Wide Web’s exponential growth. This was in 1993.
From then on, Netscape decided to improve upon its initial innovation. At this point, web pages could not do much more than click and load. Netscape sought to change that.
In the process, they developed a new browser and started embedding programming languages to alter the user experience.
Finally, they determined that creating a new programming language would be the best solution, and so became JavaScript. JavaScript’s original legacy to make web pages come alive is demonstrated by its features.
Features of JavaScript
As a client-side scripting language tailored to the browsing experience it is made to support all major browsers with full integration of HTML/CSS.
Its description as a scripting language means code can be written right into HTML and executed at run-time without the need for prior compilation.
Ultimately this reduces the load on the server each time you run a project with JavaScript.
JavaScript code is also object-oriented, meaning front-end developers can create objects that can be manipulated.
Objects contain data that can be modified which helps coders manage the different elements of an application.
These unique characteristics all contribute to JavaScript’s success. You should study examples of how JavaScript is employed in order to understand the nuances of why JavaScript is preferred amongst developers.
In the same vein, you will recognize how using JavaScript can be advantageous to your business.
How Does JavaScript Work?
The majority of web applications work on the server-side. Essentially, this means that their functionality depends on the interaction of your device (i. e. a smartphone or laptop) with a remote server. The device in this case is the client.
Once a connection is established, the server is able to provide information for the client. With the use of the client’s software, the information can then be received in the form of a webpage.
This process might seem rather long though it’s clear why certain web applications like search engines would rely on this blueprint.
In every other scenario, it is easy to see why JavaScript has garnered favorability among developers.
In client-side web applications, the programming language in question is tasked with running inside an Internet browser, known here as a Web client. This client connects to the Web server to retrieve web pages.
The browser is deployed with a built-in interpreter to read and run the code. JavaScript operates on these premises.
Additional JavaScript Functionality
There are a few other subtleties that define how JavaScript works.
For instance, JavaScript has a feature for autocomplete, making the strenuous charge of coding in itself much easier for developers.
The adaptable libraries of JavaScript mitigate browser compatibility issues towards that same end.
Likewise, with HTML form validation, JavaScript validates input from Web forms and prevents faulty or empty inputs from being returned.
On the user side, JavaScript can play both audio and video. Image rollover, which occurs when a cursor moves over an image and the image changes, is another feature of JavaScript, as well as dropdown menus.
JavaScript examples related to its graphic prowess include the ability to fade, resize, or relocate page elements through animation.
For each of these examples of JavaScript’s utilization, there are many more. Since its inception, JavaScript has never failed to prove its usefulness.
JavaScript has the aptitude to invigorate your web pages and your business thereof.
What Are the Advantages of JavaScript?
Given an elementary knowledge of JavaScript, it’s not difficult to discern the language’s value.
But your business has to compare how it ranks with other languages.
Your business must factor in competitive brawn just as much as applicability in any strategic decision.
You must know what qualities permit JavaScript to rival and beat its competitors.
Speed & Efficiency
It was previously established that JavaScript is a client-side language.
Such a descriptor makes JavaScript habitually fast. In turn for making a house call with a back-server, JavaScript simply runs, easing up on the server and delivering swift load times.
So long as there are no outside resources to pull, speedy results will be the norm.
Customers, of course, do not have the patience or will to deal with lag. They come to your business to get their impulses assuages and quickly at that.
Simplicity
Most developers consider JavaScript to be easy to learn and use. Keeping this in mind, your business will find it fairly easy to find software developers that code in JavaScript.
The faster your business can find developers, the faster your application can be built and released to the market.
Popularity
JavaScript’s popularity has similar effects to its simplicity. First, finding JavaScript developers will be straightforward.
Another advantage, however, is the accessibility of information. Many people are programming in JavaScript. Thus, you will have many examples of JavaScript projects to take insight from.
GitHub and Stack Overflow are great resources for looking at how others handle JavaScript management.
Interoperability
Like mentioned, JavaScript is widely supported and can be applied to any webpage. Other scripting languages are far less flexible.
Many different programming languages, like Pearl and PHP, support JavaScript too.

Interface Development
JavaScript sustains Netscape’s earliest objectives by continuing to offer users powerful interfaces with receptive tools to enhance the user experience.
Drag and drop, sliders, and other mouse events are only a few examples of JavaScript’s capabilities.
Add-On Extensions
JavaScript developers have the prerogative to write small clips of code that seamlessly integrate third-party apps onto a web page.
Many browser adds-on you likely already use are examples of JavaScript in action.
Variability
JavaScript has an abundance of libraries and frameworks: AngularJS, ReactJS, SvelteJS, and others.
This versatility gives developers leverage to build a variety of app types with distinctive attributes.
What’s more, it’s entirely possible to use almost exclusively JavaScript for your project’s technology stack.
Upgrades
JavaScript has been releasing updates on an annual basis starting a few short years after its formulation.
For this reason, businesses can always trust JavaScript to be up-to-date and stay current. Being outdated is the least of JavaScript’s concerns.
JavaScript is not only useful, but it carries an edge that many other programming languages do not.
Fast, flexible, and multifaceted are key principles when it comes to JavaScript’s dexterity.
When Is the Use of JavaScript Is Recommended?
JavaScript’s primary use is to transform web pages from static to dynamic. Think back to the last interactive experience you had on the web.
You can probably credit JavaScript with fabricating their experience.
Adding behavior to web pages is at the core of JavaScript’s pervasiveness. Many of these behaviors have been mentioned.
Sliders, dropdown menus, animations, audio, and video, can all be categorized as behavior changes.
Here are some other examples of JavaScript’s implementation towards web page behavior:
- Showing or hiding information
- Zooming in/out
- Displaying a timer or countdown
- Gallery carousels on homepages
Apart from merely influencing web page behavior, examples of JavaScript’s use are well-established and variable.
Is JavaScript Front-End or Back-End?
Languages used for front-end development are more practically applied in regards to the look of a website.
Comparatively, languages used for back-end development perform most effectively when managing how a website works.
To put it one way, front-end languages are the actors and back-end developers are behind the scenes directing the actor and dealing with production matters.
Because of the versatile nature of JavaScript, it is both a moving performer and a wonderful executive partner.
That is, JavaScript functions well at the front-end and back-end sides of development.
On the front-end, JavaScript works with the likes of HTML and CSS to optimize web pages for the use. At the back-end, JavaScript positions Node.js to manage data and handle user requests.
Whichever way, JavaScript is a powerful language. Full-stack JavaScript describes examples of JavaScript being maneuvered at both ends of development.
JavaScript’s faculty to wield strength in this fashion indicates how developers and businesses can use JavaScript to their advantage.
6 Examples of JavaScript Applications
JavaScript, when used at either the front-end or back-end or even for full-stack development, offers developers a diverse range of applications.
The following JavaScript examples explain in detail the varying uses of JavaScript.
1. Presentations
Developers have the option of recruiting two JavaScript libraries, RevealJS and BespokeJS, to generate a slide deck on the web.
RevealJS is an HTML presentation framework that implements touch into its programming.
Hence, online presentations can be accessed by those with mobile devices like phones and tablets. This framework supports all CSS color formats as well as miscellaneous themes, transition styles, and backgrounds.
The BespokeJS plugin is a feature-heavy framework that supplies rich properties such as scaling, animated bullets, and syntax highlighting whilst coding. BespokeJS is characterized as being lightweight.
2. Web Development
Web development involves all the behaviors enlisted to create a dynamic and interactive web page.
In addition to performing web page interactions, JavaScript can open PDFs, run widgets, and load web page content in the absence of a refresh.
3. Server Applications
Node.js is the most frequently used runtime environment for JavaScript, where developers can write, test, and debug code. Through Node.js you can write server-side software.
An example of a JavaScript server application is the Opera Unite feature of the Opera Browser.
Opera Unite lets users run server applications like file sharing and streaming straight from the web browser.
4. Web Applications
Angular and Vue.js are popular JavaScript frameworks that developers make use of during app development.
Netflix and PayPal were developed with AngularJS and APIs.
An application programming interface (API) is a protocol for accessing web-based software.
5. Games
Games in JavaScript tend to harness the EaselJS library, a library known for its rich graphics. JavaScript and HTML5 are a favored combo for creating games on the web.
HTML5 is designed so that you have full access to the web unaccompanied by additional plugins like Flash.
To that end, it’s cross-platform, so you won’t have to bother with switching devices to get a full web page.
6. Mobile Applications
Mobile applications are built to be stand-alone apps void of any web-based context. JavaScript developers look to React Native and ReactJS for this type of development.
- React Native
React Native serves the purpose of mobile app building well as it specifically supports the implementation of native features into hybrid apps. Though hybrid apps use web technologies, they can be launched from a mobile app platform without opening a web browser.
- Virtual DOM
ReactJS is responsible for building user interfaces. It is often used for the base of mobile apps.
The document object model (DOM) is a chief component of ReactJS. Consider DOM as an API for HTML and XML documents, allowing the user to read and manipulate the content on a page.
Virtual DOM (VDOM) entrusts the cache to hold a virtual instance of the DOM in memory. VDOM works in place of DOM as a less intensive clone where developers can edit a single component of the DOM at a time.
Only the changes will be synced with the original DOM. In refusing to render the real DOM, VDOM solves the issue of building large applications where data changes often, speeding up operations as a whole.
- Single-way data flow
Single-way data flow, alternatively called unidirectional data flow, is a feature of React.
This type of data flow refers to when data is transferred from one part of an application to the others in only one way.
Developers have better control of the flow of data with single-way data flow versus two-way data flow in which the values passed to a component are mutable.
