comparing values in playwright

What is exact problem you're facing? Getting price values or comparing?

Comparing, I mean, prices are being displayed in the card. Now the problem that I'm facing is to read those prices and compare them in e2e scenarios

You can use locator.evaluate to get the text. Something like this: expect(await tweets.evaluate(node => node.innerText)).toBe('10 retweets'); https://playwright.dev/docs/next/api/class-locator#locator-evaluate

I assume you need it in a variable, so I think it's const textToCompare = yourlocator.evaluate(node => node.innerText);

Once they're stored thus, you can use standard javascript comparison functions
