In many tutorials, I have seen this solution being used to show or hide content based on whether there is information in an API output.
At first glance, it seems like it should return false, but it doesn’t because the console log contains nothing. It’s not a space or any visible character—it’s something that has a "size" of zero but evaluates as true in a boolean context.
I was looking for a quick solution to show and hide content, and the only approach I found was: API output > size > greater than 0. However, this isn’t perfect because it takes a fraction of a second to compute, causing unintended elements to briefly appear.
Another approach I found was setting a default value of false for everything and updating it to true on load if the value exists. But this results in unnecessary variables in the app.
What method do you use to show or hide content based on API output?
