In this lesson, we addressed a critical issue in our button component and explored dynamic content management using props and children in React. Here's what you need to know:

Fixing the Button Issue

Previously, our buttons had static text baked into the component, which violated the principle of reusability. We updated the button to accept dynamic content through props and children.

Steps to Fix the Button

1. Convert Static Text to a Dynamic Label
   Replace the hardcoded text with a prop, such as label.

   const Button = (props) => {
       return <button>{props.label}</button>;
   };
   

2. Pass the Label as a Prop
   When using the Button component, pass the desired label value:

   <Button label="Discover Things" />
   <Button label="Discover Stuff" />
   <Button label="Discover Things and Stuff" />

Leveraging props.children

Instead of relying solely on props, we demonstrated how to use the children prop for flexibility.

Example Using children:

Modify the button to render content based on props.label or fallback to props.children:

const Button = (props) => {
    return <button>{props.label || props.children}</button>;
};

Usage Example:

Pass inline content as children:

<Button>Explore the World</Button>

Or fallback to the label prop:

<Button label="Discover Adventures" />

Key Takeaways

• Dynamic Content: Always structure components to allow for dynamic data through props or children.
• Flexibility: Choose between props.label for explicit data or props.children for inline content based on the use case.
• Best Practices: Prioritize reusable and readable components to simplify future updates.
