We, as React developers, often tend to over-engineer our applications by relying too heavily on the Context API and Redux in situations that they aren’t actually needed. We reach out too quickly for these tools — even in basic situations that simply require passing state/data to deeply-...
React passing a prop to components return undefined, Props is received as an input to your constructor function (i.e. constructor (props) ), and therefore should be referenced as such. If you need to manipulate it before rendering or manage it locally you can pass that to the state for S...
Whatproptypedoes is that it checks the type of props we are passing in our codes to ensure that it is the right one; when we pass a wrong one, theproptypealerts through the browser’s console. PropTypesShape in React ThePropTypes.Shape()offers a deeper level of type-checking and validat...
But, two of them aren't event used in RepLogs! We just pass them straight to RepLogList! This "props passing" can be kind of annoying. But, it's not necessarily a sign of bad design. It's just part of using React. There are ways to organize our code to help this, but many ...

Prop Drilling is the process of passing data(props) from parent component to a deeply nested child component in a React application. This process involves passing data through multiple intermediary components to reach final child component. The intermediary components may not use this data, and may...
In this case, the fix is to make sure that you are passingallof the arguments to the inner function. There is a more in-depth explanation of how to fix iton this page. Alternatively, you can temporarily keep usingReact.PropTypesuntil React 16, as it would still only warn in this case...
Simple enough, theSwitchneeds a reference to thetoggleandonstate, so we're sending some props there. Let's refactor it once more to add another layer in our component tree: functionToggle() {const[on,setOn]=React.useState(false)consttoggle=()=>setOn((o)=>!o)return<Switchon={on}onToggl...
