replaced with

test.expect(callable(add(666)), 'not callable')

your solution now passes; thanks for the coming up with concrete details

can you give an example of such a solution ?

Please note in Go language, the function Add should be passed a parameter/argument named not only a type. Avoid confusing beginners..
Code placeholder shouldn't be faulty I think

the dis is not clear

You can't just return n. You need to return a function. Look into that and you'll eventually come up with a correct approach.

hey guys I'm just starting my journey JS and having a challenge with this kata. From the examples given in the description it looks there should be a way to access the existing value of the variable we want to increase with the add() function. I figured the first time the function to called by a variable without a value i could just 'return n'. but that doesn't help with a variable with an existing value. can someone tell me a better approach?
