Okay so in the above challenge, it wants me to only display elements of the array which are positive integers.

All I have done so far for the part of code which should be edited as mentoned per comments is :


 const squaredIntegers = (arr) =>  ...

I have no clue how to do this with the content taught so far. I have done each tutorial in the order FCC has set out the course. How am I supposed to get started with this using what has been taught so far?

Do a research about filter and map method.

The curriculum do not mention any of that before this lesson I think, so it’s ok to feel lost with this challenge. By the way, if you don’t feel too confident with arrow functions, I’d also advise you to take a look at another resource for this matter.
