JavaScript for Line of Business Applications

In this article we will exploring more about DocType and will understand how does this effect the page rendering.

Creating impressive presentation is an art. For a long time PowerPoint stood alone as the de facto tool for creating presentations.

Now, things have changed, as the web has become the focal point for all businesses, and as browser capabilities improved tremendously. Modern browsers are now capable of rendering 3-D graphics and animations just like in any other native applications.

Then there came some cool presentation libraries based on HTML5 and CSS3. Reveal.js is a highly popular library for creating stunning presentations.

Websockets is a new standard defined as a part of HTML5 spec, which enables bi-directional, full-duplex communication in browsers. There are number of JavaScript libraries that make working with Websockets easier, of which Socket.IO is a prominent one.

In this article we’ll discuss how to create a Reveal.js presentation that can be controlled by multiple users. We’ll make use of Socket.IO for sending and receiving slide change events in real-time. Reveal.js already comes with a multiplexer plugin, but this is a bit difficult to set up so we’ll ignore that for the time being. Let’s focus on how we can write a Socket.IO server that’ll suit our purpose.

We're a growing community of developers united to push the boundaries of HTML5 and revolutionize digital experiences.

Our community is built on developer stories, showcasing great work, and cultivating forward-thinking ideas. We're spreading the word throughout the global community.

Uniting developers across the world, we can better shape the future of HTML5. We share a common goal of consistently pushing the limits of web and cross-platform app technology.

When you use reusable components (whether through convention, a framework like Fruit Machine or React, or directly using the emerging Web Components standard), you might find that components ship with polyfills. Your page may end up containing multiple polyfills for the same feature. You might also find that these polyfills all use slightly different implementations, and it’s not immediately obvious which is a faithful emulation of the missing feature. Even the packaging format and file structure is likely to vary between polyfills and make each one a special case.

This is far from ideal. We need some way of polyfilling browsers that avoids this duplication.

Parallel.js is a library for performing parallel computing in Javascript using web workers.

Parallel.js is a tiny library for multi-core processing in Javascript. It was created to take full advantage of the ever-maturing web-workers API. Javascript is fast, no doubt, but lacks the parallel computing capabilites of its peer languages due to its single-threaded computing model. In a world where the numbers of cores on a CPU are increasing faster than the speed of the cores themselves, isn't it a shame that we can't take advantage of this raw parallelism?

Parallel.js solves that problem by giving you high level access to multicore processing using web workers. It runs in your browser (as long as it supports web workers). Check it out.
