UNDERSTANDING WORKFLOW OF REACT APP

React JS – Render HTML

• In React App, react renders HTML to the web page by using a function called ReactDOM.render().

The Render Function

• The purpose of the RENDER function is to display the specified HTML code inside the specified HTML element.
• But main question is render where ?
• Look inside your react directory structure, there is another folder in the root directory of your React project, named “public”. In this folder, there is an index.html file.
• You will notice a single <div> with id “root” in the body of this file. This is where our React application will be rendered.
