I would also read the documentation. In the given example, for example, you don't know if the desired fixed format "YYYY-MM-DD" might depend on some locale setting and only works because you happen to have the correct one in that test console.

Part of my point is this: If you have to read through the docs to see if the answer can be trusted, why didn't you just read the docs to begin with instead of asking the AI?

[niccl]

It's just dawned on me that one possible reason is that you don't know which docs to read. I've recently been forced into learning some JavaScript. Given the original question I wouldn't have known where to start. Now the AI has given me a bunch of things I can look at to see if it's the right thing

[freeopinion]

If you didn't know enough to provide the original prompt, the AI sends you down the Date path instead of Temporal. But you could have used a 20 year-old search engine that would lead you to Javascript docs. You don't need error-riddled AI-generated code to find your way to the docs.

Are you saying there is more than one way to solve most problems in life? I don't believe it! Obviously, only what you personally like is the one true way. /s

[nosianu]

Because you skip the step of finding out which docs to read. You get the specific functions and what parts of it you should check presented to you. Also, you only need to do this when it isn't already clear.

I’m pretty sure toPlainDate() returns an object not a string.

???

What does that have to do with my comment?

The OP explicitly wrote

> prompt> use javascript to convert a unix timestamp to a date in 'YYYY-MM-DD' format using Temporal

> answer> Temporal.Instant.fromEpochSeconds(timestamp).toPlainDate()

The answer ends in `toPlainDate()` which returns an object with year, month and day properties. ie it does not output the requested format.

This is in addition to the issue that `fromEpochSeconds(timestamp)` really should probably be `fromEpochMilliseconds(timestamp * 1000)`
