Using a panel might look a little like this: As you can see, we're adding content inside of the tags. and when we can using children inside the child component don't need to use {props.children}, @AlpitAnand You can see reference at the end of the answer :|.
Reference: A quick intro to React’s props.children. props.children represents the content between the opening and the closing tags when invoking/rendering a component: Thanks for contributing an answer to Stack Overflow! {this.props.children} includes those children in the rendered result....what are the situations to use the same Being a beginner to React world, I want to understand in depth what happens when I use {this.props.children} and what are the situations to use the same. If children only contains one child, it’ll wrap that child in an array, which you can then slice() and concat() like a ninja. Let's update the previous example with an additional Button component for toggling. To send props into a component, use the same syntax as HTML attributes: Example. {this.props.children} includes those children in the rendered result. Below is an example of a basic React component: The above component would render the message, "Say Hello to learning Props/State in React!"

Stack Overflow for Teams is a private, secure spot for you and Now, how do we render that content in our component? The function can then update the state in a parent component, as we saw above.
I’ve since learned a bit more about this.props.children and see now how it is used and how it can help make your React components more flexible and reusable. Thus, all the relevant components get rendered again. this.props对象的属性与组件的属性一一对应,但是有一个例外,就是this.props.children属性,它代表组件的所有子节点,举一个官方的, NotesList组件的两个span子节点,都可以通过this.props.children获取,这里需要注意, this.props.children 的值有三种可能:如果当前组件没有子节点,它就是 undefined ;如果有一个子节点,数据类型是 object ;如果有多个子节点,数据类型就是 array 。所以,处理 this.props.children 的时候要小心。. React provides a number of powerful patterns to compose components; for example, Containment, Specialization, and Render Props. Which “href” value should I use for JavaScript links, “#” or “javascript:void(0)”? When passing objects, the syntax can be a bit confusing initially as we'll have two curly braces: one to represent our JSX and another for the object. In general, we can pass the logMe method to Child components by using props but in our case, we are using this.props.children so that we didn’t have a direct way to pass the data. Consider in the previous example if we had wanted to wrap each paragraph in its own

element:

React.Children.toArray(children) Returns the children opaque data structure as a flat array with keys assigned to each child. In the example above, the data was a string variable. But our Button component is not aware of the business logic of the click handler.

Our MovieBrowser component would look something like this, before we added the prop: Now let's add in our isPlaying prop to the children of MovieBrowser: React.Children.map has two parameters: the first one is the children themselves, and the second one is a function that transforms the value of the child. What is {this.props.children} and when you should use it? We'll cover what this.props.children means in the context of a React component. func. It just knows that it needs to trigger the function whenever a user clicks on the button. It was not clear in the given link that what happens when I use {this.props.children} inside a component. in the browser.

Here’s an example of a stateless function that is used to create a component. @Nimmy when using {props.children} we don't have performance issue, just need passed component as props. Whenever this component is invoked {props.children} will also be displayed and this is just a reference to what is between the opening and closing tags of the component. How does the highlight.js change affect Stack Overflow specifically?
