React JS Props: React is a programming language used to quickly and efficiently create robust applications and software. React props are a singular aspect of React used to help simplify the passing of data from one component to another. However, it is not the act of giving props to one of your friends, that is very different. Instead, it’s how an application shares data across different parts of a piece of software.

What are React js props?
In React, the term props stands for properties, which refers to the properties of an object. This is because all elements created in React are JavaScript objects. As a result, passing data into a component is done by creating properties and values for the object. Understanding how to use props in React can be a little confusing at first due to the unique way it behaves. React props are read-only, that is to say, once the data has been passed to its component, it cannot be changed. It may sound like that creates a serious limitation to the use of props in your React code. But it really isn’t, in fact, it adds a layer of protection to both security and performance. Props work through passing data into a component to be used, typically for UI needs.
How to Use Props in React?
Not all components will use props, that is reserved for components with data to display. The benefit of this is that it creates a more efficient user experience with code that executes quickly. React props can be thought of as rain falling on layers of soil, typically the flow is down, not up. Because of this, the element that uses the props value is generally the child of the component that contains it. In React props are used primarily to display data that does not change, to render data that needs regular updating you’ll need state.
“This can sound a little confusing, so let’s look at some code examples to illuminate this process.”
