KNOWN ISSUE: so return NaN passes the deleteFromDriverByKey test?

[arye-eidelman]

function deleteFromDriverByKey(driver, key){
  return NaN 
}
// why does this pass the test 

This is what I actually tried and it passed the test just fine without me realizing that it was actually returning NaN

function deleteFromDriverByKey(driver, key){
  return driver - driver[key]  // NaN 
}

Only when I went to the next function and tried a similar answer which didn't work did I open up the debugger and realize that it was returning NaN

function destructivelyDeleteFromDriverByKey(driver, key){
  driver -= key
  return driver
}
