Understanding higher-order components

  • Why use HOC: Promote reuse of logic across React components.
  • How to use HOC: The core structure of a HOC is a function that takes a component and returns a new component.
  • HOC are pure functions with no side-effects because the component passed in, is wrapped in a new component.
  • The HOC looks like this: – – State now has a property to inject data from the API fetch into the wrapped component via the prop.
  • React Redux connect has a different function signature of a function returning a function which accepts one argument (ie, ‘component’) to create a HOC.

Why You Should Consider ReactJS for Your Web Application?

Here's Why You Should Consider #ReactJS for Your #WebApplication.

#Programming

  • Yes, we are talking about ReactJS – the JavaScript library which is the hot favorite of developers and is climbing the popularity charts every day.
  • Managing system updates is very easy with ReactJS because every change does not necessarily affect each component in the system.
  • Developers using ReactJS have free access to a variety of useful applications and tools from the community at large.
  • Apart from these, there are numerous other examples such as Uber, Salesforce, KISSmetrics, Tesla, Scribd, Reddit, Periscope and many more which have leveraged the power of ReactJS to build world-class interactive web applications.
  • If you are looking to develop SEO-friendly, interactive web applications with great UI and expect your application to handle heavy traffic, it’s time to migrate to ReactJS.

According to the 2016 StackOverflow developer survey, React.Js’s popularity had recently increased by over 300%.What is making ReactJS so popular? Let’s take a look why you should consider ReactJS for your web application?

Using React Fragments for the first time

  • Up until React 16 each component had to return a single element: – – With the release of React 16, you were able to return an array of elements that a component would render: – – This is OK; but it has two problems: – – Because returning arrays didn’t…
  • On a large application with a suite of components this can very quickly lead to a set of wrapping elements that can produce a big set of HTML soup.
  • The difference is that a component doesn’t end up adding any extra markup into the DOM: – – First, we import just like we import from : – – And then we use it just like any other React component: – – The key here is that the resulting DOM…
  • However, swapping out the string interpolation using ES2015 template strings for a React suddenly made the entire code easier to follow, and allowed me to use an HTML entity: – – This is now easier to follow and allows me to use HTML entities and have them work as expected….
  • Not only do they clear up a lot of component code, but the fact that they have no output into the DOM should lead to fewer superfluous and elements that a lot of React applications are littered with.

React v16 was a very exciting release for React, and included many new features. In the recent React 16.2 release, improved support for Fragments was announced, and it’s this feature that I want to talk about today.
