If you have a lot of props that you're passing down to your component, it may be best to include them on the entire props object and access them by saying props.propName. Or they can be destructured, since props will always be an object, into separate variables. Props can be accessed as an entire object which is usually called "props". There are a couple of patterns we can use for accessing prop values in our components. React props can be accessed as an object or destructured Instead, you can just include the prop value, and it will be given the boolean value true when you use it in a component to which you pass it. There is no need to write that a prop is equal to true. If you just provide the proper name on a component with nothing else, you pass a boolean value of true for that prop to the component. ![]() React props passed with just their name have a value of trueĮvery prop must be given an associated value that is provided after the equals operator.īut what happens when we don't provide that equals operator as well as a value? Also you might not pass a certain prop to a component, if you so choose. In plain React, be aware that passing props can be something you forget to do. With prop-types or TypeScript, we can tell React the props we are passing for a given component, what their values should be, and whether they are optional. If you would like to be alerted to when a value is not passed as a prop to a component, you can use a tool like prop-types or TypeScript using these tools. ![]() Instead, within the component that prop will have a value of undefined. If prop values are not passed a certain component, an error will not be thrown. Props that are passed to components can be thought of like arguments that are passed to a function. ![]() It includes all of the essential information here as a convenient PDF guide.

We will not only touch on what these patterns are and how to use them, but you'll see how to use them on your own through practical, real-world examples. In this tutorial, we will be reviewing ten patterns you should use when working with props in React. Props are a powerful tool to use in React, but how do you use them effectively to write robust, reliable React components and applications?
