A bit of a personal preference but for enums I do the following:
Suggested change
| export enum TicketStatus { | |
| CLOSED: 'closed', | |
| OPEN: 'open', | |
| WAITING_RESPONSE: 'waiting response', | |
| } | |
| export enum TicketStatus { | |
| Closed = 'Closed', | |
| Open = 'Open', | |
| WaitingResponse = 'WaitingResponse', | |
| } |

I would also mention to use const enum where possible.

| We can assign any value to our enumerable properties, in this previous example, if you had numeric values for your variable then it'd look like this: |

This sentence is a little hard to read. We should break it up a little.

| So when you or someone else is working later on the code they can use the enum like this: |
| // do something | ||
| } | ||
