What is a Portal anyway? Well, as quoted in the google dictionary, its “a doorway, gate, or other entrance.”
React v16.0 brought a similar concept of Portal that provides a way to transport a piece of UI into some other locations on to the DOM Tree while preserving its position in the React hierarchy, allowing it to maintain the properties and behaviors it has inherited from the React tree. Isn’t that amazing, you put your component in one place, and after the rendering, it’s somewhere else in the DOM tree.
