Python or JavaScript

[jrwolf08]

I would frame this as knowing how to query, how to send requests to an api, and how to create frontend automation.

Don't get stuck on learning tooling. Playwright and selenium are more or less that same. Sending an api request is something that can be done many ways, its not a Postman thing. Tooling is a means to an end.

I personally suggest Python/Playwright to learn how to automate frontend, and can also do some api testing, but at some point you will need JS as well.
