React allows us to create reusable UI components. React, sometimes referred to as a frontend JavaScript framework, is a JavaScript library created by Facebook. It was first deployed on Facebook's News Feed in 2011 and later on Instagram in 2012. When rendering a component, one can pass the values between components through "props":[10]. It is declarative, meaning that you write the code that you want and React takes that declared code and performs all of the JavaScript/DOM steps to get the desired result. These components are reusable and must be formed in the SRC folder following the Pascal Case as its naming convention (capitalize camelCase). Here are three places you'll find it being used: Web development This is where React got its start and where you'll find it used most often.

Function components are declared with a function that then returns some JSX. JSX is similar to another extension syntax created by Facebook for PHP called XHP. This allows the choice of whichever libraries the developer prefers to accomplish tasks such as performing network access or local data storage. It is declarative, meaning that you write the code that you want and React takes that declared code and performs all of the JavaScript/DOM steps to get the desired result. Server-side rendering refers to the process of rendering a client-side JavaScript application on the server, rather than in the browser. [56], On September 26, 2017, React 16.0.0 was released with the MIT license.

The following is a rudimentary example of using React for the web, written in JSX and JavaScript. The ReAct Toolbox. [35] However, major changes to React go through the Future of React repository issues and pull requests. [25] Similar in appearance to HTML, JSX provides a way to structure component rendering using syntax familiar to many developers. "No New Features" enables gradual React updates from older versions. Lifecycle methods for class-based components use a form of hooking that allows the execution of code at set points during a component's lifetime. The ReAct Toolbox is a user-friendly web-based resource that provides inspiration and guidance to take action and develop national action plans on antibiotic resistance.
