Pass information with props

Objective: Pass typed props to make one component display different content.

Understand the idea

This lesson focuses on pass information with props. Pass typed props to make one component display different content. We will use a familiar community situation to make the idea concrete, then break it into decisions you can explain. You do not need special equipment or previous experience beyond the course prerequisites.

The same event card can show a different venue, date and registration link without copying its markup. Start by naming the information or action involved, then consider what a visitor or learner needs to understand. This small planning step makes the example easier to follow and helps you notice assumptions before they become confusing.

Props are inputs supplied by a parent; a component should treat them as read-only values. The example is synthetic and contains no real organisation, personal details or promises about services. Treat it as a learning model: adapt the structure to your own situation, and check details with the people responsible before publishing anything publicly.

Define a prop shape that describes required information, then render the values in context. Do not put private data in a public interface. Try changing one detail at a time and describe what changed. When something behaves differently from what you expected, return to the goal and inspect the relevant part instead of changing several things at once.

Test the component with at least two distinct examples to check that it is genuinely reusable. A useful review asks whether the result is clear, usable and appropriate for the intended audience. Invite another person to try it when possible, and make improvements based on what they can actually understand or do.

Worked examples

Pass information with props: a small example

See how pass information with props can help communicate or solve a practical community task.

App.tsx

type EventCardProps = { title: string; venue: string }
function EventCard({ title, venue }: EventCardProps) {
  return <article><h2>{title}</h2><p>{venue}</p></article>
}

Practice tasks

  1. Explore pass information with props

    Use the worked example for “Pass information with props”. Change one small detail to suit a different synthetic community situation, then explain what you expected and how you checked whether the change still met the lesson objective.

  2. Build a React practice example

    Create a small practice result that demonstrates this objective: Pass typed props to make one component display different content. Use only synthetic information, keep the first version focused, and write down one limitation that a later version should address.

  3. Review and explain the result

    Review your “Pass information with props” result as if another learner will use it without your explanation. Identify one strength, one exact point that may be unclear, and a revision that would make the result easier to understand or use.

Pass information with props becomes easier when you start with a clear purpose, try one small step and check the result from the learner or community member's point of view.
