Create a timer that can be started and stopped

This repository is the companion to the reactpractice.dev exercise to create a countdown timer. Check out the blog post for more details.

Create a 5 minute countdown timer that can be started and stopped.

• When the page is first loaded, the counter displays 5 minutes (i.e. 5:00)
• When the user clicks "Start", the counter starts counting down.
• When the user clicks "Stop", the timer should start elapsing time.
• When the user clicks "Reset", the timer should be reset to 5 minutes again

Use React with Typescript to build you solution.
