Something went wrong!

Asynchronous Programming with JavaScript. The code provided in videos and download files does not show the result. Is the problem related to obsolete wiki API: https://en.wikipedia.org/api/rest_v1/page/summary/' ? How to check that?

Did you check the console? This code fails when one of the astronauts is missing a wiki image. You can get around this with this code inside the generateHTML function:

<img src=${person.thumbnail ? person.thumbnail.source : null}>

This is shorthand for an if statement that show the image if it exists, otherwise it does nothing. Not perfect but helps with the missing image issue.

Thanks for your answer Daniel, I was going insane trying to work out why this was happening.
