Day 5 - 30 Days learn Web Dev

4 Dec 2023

Finished 2621. Sleep

What I learn:

• Promises
• setTimeout() return a timeoutID
• clearTimeout(timeoutID)
• .finally() in promise
• JavaScript's Event Loop
• we can use promise chaining to avoid "callback hell" or "pyramid of doom"
• we can write asynchronous code that almost looks like synchronous code with the assistance of async and await, it is easier to understand and maintain
