React.js is an efficient, declarative, and flexible open-source JavaScript library that is useful for developing user interfaces specially for single page apps. With React.js, users can build complex user interfaces from “components.” Components are small and isolated pieces of code.

React.js can also be used as a base in the building of both mobile and single-page apps. Although, complex React.js apps usually require additional libraries for interaction, routing, and state management with an API (Application programming interface).

React.js makes it possible for developers to design large web apps which can change data, without reloading the page.

Hence you’ll need an iPad to debug this issue. Before listing the issues, some background about the project is below. At the start, users enter their name. This can be any string.

    The project is build using React. The primary job is to write react UI components in typescript. The scope is limited to just writing individual components where the interface has already been designed. The developer needs to simply understand the interface and write the stateless UI components. There is no integration as such to be done. We are simply expect the output to be a set of standalone components that are written as per the specification. The project is supposed to last for a while with the developer working with us in each phase doing similar task.
