Learn Recursion by Building a Decimal to Binary Converter - Step 31

Tell us what’s happening:

I have no idea what this is asking me to do, as far as I am aware and by what the test is asking, I need to console log “Inputs: ,” and then the array. I think the comma is a weird choice, and i’ve tried it without, but console.log(Inputs: ,${inputs}) should work as per the request? but i just keep failing and it’s really confusing, especially because there’s a fail state on a console.log question which is goofy to begin with.

(I had this posted at the bottom, not the top (sorry haha))

Hi! Abolutely not :slightly_smiling_face: You have to put in the console.log the given text Inputs: (with a space), then put a comma and finish it by adding inputs array.
And make sure you don’t forget quotation marks around Inputs:

4

that’s fair, but again, as far as I can tell i did that?

console.log(Inputs: , ${inputs}) is what you’re saying, correct? (the backticks are converting and i’ve no idea how to stop them

5

Nope, put the quotation marks around Inputs: , then a comma, then just add the name of the array which is simply inputs, without any signs
