Let's build some components to put those newly formed React skills to the test!
Submit an issue on this repo by 5:00PM with links to your forked repos of each exercise you completed.
Also in the submission, please include your overall comfort and completion as well as any questions or specific areas designated for feedback.
Choose one or more exercises from the list below, and implement the outlined features using React.
Build a Sign Up Form component that:
- Prompts the user to enter their email, password and password confirmation
- When the user submits the form:
- Notify the user of whether or not their submission was valid
Bonus:
- When the passwords do not match, the inputs display should be changed
- Add basic validation on a user's email (i.e. every email must contain an
@sign...)
Build a Stopwatch component that:
- Allows the user to press a button "Start" to start the stopwatch
- While the stopwatch is started, the incrementing time should be displayed
- Allows the user to press a button "Pause" to pause the stopwatch at the current time
- Re-clicking the "Pause" button should resume the stopwatch
- Allows the user to press a button "Reset" to stop the stopwatch and reset the time to
0
Bonus:
- When the stopwatch is at
0, the display time should be a different style - When the user first visits the page, the only button that should be active is "Start"
- The other buttons should be unlocked only after the user clicks "start"
Build a Shopping Cart component that:
- Allows the user to add a new item to the cart
- Each item has a name, cost and quantity
- Displays each item in the cart, as well as the calculated total of all items cost
- Allows the user to update the quantity of each item in the cart
- Allows the user to remove an item from the cart
- Allows the user to wrap an item as a gift for an incurred cost
- Calculates the sales tax and adds it to the subtotal of the items to be purchased
Bonus:
- Allows the user to enter a unique promo that applies a pre-designated discount off the total of the cart
- Your cart should be initialized with a list of predetermined promo codes, and only valid inputed codes receive the discount
- No promo can be used more than once
- Plan first!
- Sketch a quick wireframe of what your component will look like
- Make a mental list of all necessary data attributes to be tracked by your component
- Think of the types of user actions and how each action changes the component

- Components and Props
- Adding State to a Component
