# JavaScript Promises (Day 2)

# What are the three states of a Promise?

Pending, Resolved and Rejected

# How do promises seek to resolve the issues of "callback hell"?

Promises can be chained together letting developers write cleaner code. Instead of trying to nest a ton of requests inside each other, you can use promises to chain them together.

# What is the difference between .then() and .catch()?

.then() is used for when promises are resolved successfully, meanwhile .catch() is for rejected promises.
