JavaScript Promises

What are the three states of a Promise?

• Pending - Initial State
• Resolved - Completed Promise
• Rejected - Failed Promise

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

They make the code look cleaner and easier to read. They use a process calling chaining.

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

• .then() is only used for resolved Promises.
• .catch() is used if the Promise gets rejected where you can console log the error or a message.
