Pull Request Overview

This PR adjusts the code example in the Discover Promises guide to import the full fs module and use its promises property, rather than requiring the promises API directly.

• Swapped require('node:fs').promises for require('node:fs')
• Updated the readFile call to use fs.promises.readFile

Comments suppressed due to low confidence (1)

apps/site/pages/en/learn/asynchronous-work/discover-promises-in-nodejs.md:162

• Consider adding a note about Node.js version requirements for the direct require('node:fs/promises') import, as it’s only available in Node.js 14+.

const fs = require('node:fs');

Why is this better? It's the exact same thing, except the previous example worked interchangeably with the code comment, and this would break if you replace the imported version with the promise version.

its better because the text below the code snippet says fs.promises.readFile().

[AugustinMauroy]

IMO it's cool and more readable

I think we should update the text to match the example. This example is purposely formatted in such a way where that time can be replaced with an fs/promises import and be used the same

Yes it makes sense.
