Each level of interaction for this form is represented by the state, from an empty form to being a fully filled form with a display of an error for certain fields and the validated form. These states represent at which level the application is, in terms of interacting with the end-user. So, at a broad level, the registration form has been through various states. When the form field is empty or when the form field has witnessed some error on some particular field, which needs to be corrected or when after correction, the form data has been validated and is ready for submission. While filling the details there can be many states of the form, for e.g. To become a member of a service, the user fills his information on the registration page. We will look into the pure component later. A component in case of React can be thought of as a piece of code which is based on the principle of pure functions. Components have hierarchy in terms of Parent and Child components. In React we have the concept of states and the concept of immutability. This advocates the idea of building web pages and applications using components and unidirectional flow.
It utilises the syntax of the modern version of JavaScript as described by ES6 and its higher version.Īpplications built using ReactJS use the Single reusability principle. ReactJS is a library written in TypeScript. At least one installed code Editor to test and debug your code e.g.Active internet connection minimum speed 512kbps and above.Windows XP, Windows 7 (32/64 bit) or higher.To install React on Windows, your system will require the minimum configuration as below:
Various startups and established organizations are now adopting the technology and upgrading their technology stack. The adoption of ReactJS has seen an upward curve since its advantages have been realized. React was an inhouse project of Facebook, and it was made open to the public in the year 2013. React is a library that helps us to build and create front end interfaces for Single page applications and it utilises the power of virtual DOM. In this tutorial, we will learn how to install React JS in Windows.
