什麼是 {this.props.children} 以及何時應該使用它？ - What is {this.props.children} and when you should use it?

問題：

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.作爲 React 世界的初學者，我想深入瞭解使用{this.props.children}時會發生什麼以及使用它的情況。 What is the relevance of it in below code snippet?它在下面的代碼片段中有什麼相關性？

render() {
  if (this.props.appLoaded) {
    return (
      <div>
        <Header
          appName={this.props.appName}
          currentUser={this.props.currentUser}
        />
        {this.props.children}
      </div>
    );
  }
}
