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.

    Hello, I want a website similar to Amazon. But that the payment is made through cryptocurrencies and other functions that I will comment on privately. I want the crypto to go to the website wallet first and then when the buyer accepts the service as received, the money will automatically go to the seller's wallet. There are no ethereum contracts as we don't want to be saddled with their huge gas fees. Only experienced people, no wordpress, don't waste my time. If the project is carried out well, there is a high possibility that they will be hired again for a much higher salary for a long period of time.
