Full-stack JavaScript describes examples of JavaScript being maneuvered at both ends of development. 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. 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.
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. Through Node. Opera Unite lets users run server applications like file sharing and streaming straight from the web browser.
Angular and Vue. HTML5 is designed so that you have full access to the web unaccompanied by additional plugins like Flash. Mobile applications are built to be stand-alone apps void of any web-based context. 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.
ReactJS is responsible for building user interfaces. It is often used for the base of mobile apps. 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. 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. Its object-oriented framework helps developers code with dynamic functions in mind, resulting in an interactive experience for any given user. At Trio, you can find remote developers that can manifest the potential of JavaScript in real-time.
In very much the same way, Trio will revive your business as well. Take your business to the next level and hire JavaScript developers with Trio. JavaScript is the programming language that made the World Wide Web what it is today. Speed and efficiency; simplicity; popularity; interoperability; interface development; add-on extensions; variability; upgrades.
JavaScript functions well at the front-end and back-end sides of development. Common examples of JavaScript uses and applications include: Presentations Web Development Server Applications Web Applications Games Mobile Applications It is important that you learn how to utilize such a language for the benefit of your own business.
What Is JavaScript? How Does JavaScript Work? It can also load content into a document whenever the user requires it without even reloading the entire page. With technology browsers and personal computers have improved to the extent that a language was required to create robust web applications.
When a user explores a map in Google Maps then the user just needs to click and drag the mouse. All detailed view is visible by just a click. This is possible due to JavaScript.
It interacts with the browser without sending messages to and fro to the servers. JavaScript also provides the facility of creating presentations as a website. A user can easily insert nested slides. Even if the user is not aware of programming language then they can easily build a site with so much help online. These presentations are touch optimized and work great with mobile devices, phones, and tablets. With all this JavaScript also provides different transition styles, themes, and slide backgrounds.
It supports all CSS color formats. JavaScript also provides Bespoke. These include responsive scaling, animated bullet lists, and syntax highlighting for code examples.
It provides themes which are polished and not too flashy. The quickest way to start Bespoke. It allows the user to set titles to your presentation and go through a set of questions to get the plugins required. It uses event-driven, lightweight and efficient applications which are to be distributed over the systems with the help of a server.
The back end refers to the behind-the-scenes code that makes a website work on a web server. For instance, you can use JavaScript with Node. A JavaScript back-end could process payments, save user posts, and do any of the other behind-the-scenes work that a website needs to run. Traditionally, mobile applications were developed using languages specific to an operating system.
However, in recent years, several technologies have been developed that allow you to create mobile applications using the JavaScript programming language. React Native is one example of these frameworks. It allows you to use JavaScript and React to build an application that runs on a mobile device. Phonegap, maintained by Adobe, allows you to build mobile apps using web technologies. Angular and Vue are some other frameworks you can use for this purpose.
JavaScript is used in online games. Many of these games are simple platform games because JavaScript is not as powerful as other languages for building games. There are many limitations to building a browser-based game using JavaScript.
But, the language is nonetheless often used by game developers to create simple games. JavaScript by itself does not scale very well if you want to build large games. For instance, many of the computer games high school students play today have been built using JavaScript.
The advantage of using JavaScript for basic game development is that you can create something that runs in the browser. In fact, this very web page uses JavaScript in a number of ways to display its contents.
For example, the comments box on our blog is powered by JavaScript—when you click to submit a comment, a JavaScript function is run. To help you better understand how JavaScript is used, we will show a few examples of companies that use it.
PayPal has been using JavaScript since the very beginning again, because it is so fundamental to all websites.
However, the online payment company has also experimented with tools like Node. JS to power their web applications.
This shows how much PayPal uses JavaScript. However, as its site started to grow, the company realized it needed something more efficient. From a technical standpoint, most modern JavaScript interpreters actually use a technique called just-in-time compiling to improve performance; the JavaScript source code gets compiled into a faster, binary format while the script is being used, so that it can be run as quickly as possible.
However, JavaScript is still considered an interpreted language, since the compilation is handled at run time, rather than ahead of time. You might also hear the terms server-side and client-side code, especially in the context of web development.
Client-side code is code that is run on the user's computer — when a web page is viewed, the page's client-side code is downloaded, then run and displayed by the browser.
In this module we are explicitly talking about client-side JavaScript. Server-side code on the other hand is run on the server, then its results are downloaded and displayed in the browser.
NET and JavaScript can also be used as a server-side language, for example in the popular Node. Server-side code dynamically generates new content on the server, e. The meaning is slightly different in the two contexts, but related, and both approaches server-side and client-side usually work together. A web page with no dynamically updating content is referred to as static — it just shows the same content all the time. Let's learn how this works. Note: If your example doesn't seem to work, go through the steps again and check that you did everything right.
Did you save your local copy of the starting code as a. Did you enter the JavaScript exactly as shown? JavaScript is case sensitive, and very fussy, so you need to enter the syntax exactly as shown, otherwise it may not work. Note: You can see this version on GitHub as apply-javascript-internal. This works great, but what if we wanted to put our JavaScript in an external file? Let's explore this now. Note: You can see this version on GitHub as apply-javascript-external.
It might look something like this:. Please don't do this, however. In this case the addEventListener function allows you to select all the buttons using one instruction. The code we used above to serve this purpose looks like this:. This might be a bit longer than the onclick attribute, but it will work for all buttons — no matter how many are on the page, nor how many are added or removed.
The JavaScript does not need to be changed. Note: Try editing your version of apply-javascript. When you reload, you should find that all of the buttons when clicked will create a paragraph.
Neat, huh? There are a number of issues involved with getting scripts to load at the right time. Nothing is as simple as it seems! A common problem is that all the HTML on a page is loaded in the order in which it appears. If you are using JavaScript to manipulate elements on the page or more accurately, the Document Object Model , your code won't work if the JavaScript is loaded and parsed before the HTML you are trying to do something to.
In the above code examples, in the internal and external examples the JavaScript is loaded and run in the head of the document, before the HTML body is parsed. This could cause an error, so we've used some constructs to get around it.
