JavaScript JavaScript

JavaScript is a programming language present almost everywhere on the web - from Facebook and LinkedIn to Uber or Netflix - any modern website or application that you can dream of is sure to use JavaScript.

JavaScript is a key component of modern, interactive websites alongside HTML and CSS. JavaScript, while mainly used as a front-end technology, it can now be utilized server-side as well, thanks to technologies like Node.js. JavaScript is the default language for the web - you don’t need to download any plugins, JavaScript-enabled websites are good to go for users as is.

Why is JavaScript the most popular language for web pages?

JavaScript was created to be able to manipulate data within web pages without having to send it to the server, however it’s evolved into something much more. JavaScript can be used to create on screen visual effects, calculate and process data flowing through websites, and other extended functionalities on web pages with the help of third party scripts.

JavaScript is now a web standard, supported natively across browsers and compatible with other open web standards. JavaScript is the key technology underpinning complex web applications, often paired with clever frameworks and libraries to extend it’s capabilities. Instead of using Flash (which is all but obsolete now) or other available plug-ins which require downloading elements to function, JavaScript simply works. This technology is also able to fix browser issues or issue patches in the background, for instance fixing CSS layout problems in some browsers. JavaScript code is easy to include on the page by simply adding proper HTML tag to inform the browser to fetch the script and execute it.

What are the advantages of using JavaScript?

There are numerous advantages of using JavaScript in business applications. These include:

Works in all browsers

improving user experience (UX) through elements such as charts, autocomplete, and other advanced UI elements.

Boost website response times

as the user doesn’t have to wait for the server to display another page, it’s available already from within the browser.

relatively easy to learn language, so developers are able to learn it quickly and at lower costs. It can also be run on the server-side via technologies like Node.js, without developers having to learn another language.

JavaScript & Node.js: For front-end and back-end JavaScript development

Node.js is a JavaScript runtime environment that allows us to execute JavaScript on the server side. Node.js was created in 2009 and has become popular within the “JavaScript everywhere” paradigm, making back-end development using JavaScript a possibility. It also allows you to render the client-side code on the server for SEO purposes. Node.js is event-driven and relies on a non-blocking I/O model. The technology the largest ecosystem among open source libraries with npm, Node.js’ package system.

The can be many benefits in using Node.js. Being fluent in Node.js gives developers the opportunity to be full-stack JavaScript developer. Using the Node.js runtime, they can create both the front-end and the back-end of a web application - and it can be done in easy, efficient way. Like JavaScript, Node.js is relatively easy to learn, too. From a technical standpoint, handling asynchronous I/O is one of Node.js’ strengths, solving many of the issues of request handing in web development. Additionally, Node.js’s Event Loop makes it scalable to handling large volumes of requests.

JavaScript and Vue.js: An incrementally adoptable JavaScript framework for UI

Vue.js is an incrementally adoptable JavaScript framework used for creating user interfaces. It is one of the JavaScipt technologies that has become highly popular in recent years among developers all around the world in all different projects, for use with small to medium businesses, as well as big enterprises or corporations.

Vue.js is a versatile, reactive, flexible, highly performant and approachable framework. It has very small footprint - just 18-21 KB - so it’s quick to download and start using. Even though it is small, it’s a very fast framework. Vue.js is easy to understand with a simple structure, which makes development faster, easier and less error-prone.

One of the most attractive reasons to use Vue.js is its component-based, incrementally adoptable design. This makes it a great technology to get started with an Agile approach, building the minimum viable product web app, and then incrementally building functionality from there.

The web runs on JavaScript. Build your next web project with us & JavaScript - we have the experience to make even the most complex ideas come to life.

Component-based development with React

React is another useful JavaScript framework, used for building interfaces based on components. These components manage their own state and can be used whenever needed. Once you design simple views for them, you can then use them to create complex, interactive UIs in an easy manner. React automatically updates and renders given components when the underlying data changes.

React’s declarative views result in more predictable code, making it easier to debug. It allows you to pass rich data in your app and is very pleasant to use and learn - just like JavaScript. There is a wealth of tutorials and comprehensive documentation available for React, making it fairly easy to learn with just a bit of JavaScript background knowledge. React can come with its debugging or design tools package - React Developer Tools, integrated with a Chrome or Firefox browser extension.
