Freecodecamp: steamroller fifth test fails for function names containing flat

[piouson]

Edit: sorry, same as #38491
Describe your problem and how to reproduce it:
The fifth test for Steamroller algorithm fails for function names containing flat

Your solution should not use the Array.prototype.flat() or Array.prototype.flatMap() methods.

const flatten = array => { } // this will fail the fifth test
function steamrollArray(arr) {
  return arr; // even without the function call
}

@piouson, awesome, great catch here. The issue seems to be with this testString, which is a bit too flexible:

testString: assert(!code.match(/\.?[\s\S]*?flat/) && !code.match(/\.?[\s\S]*?flatMap/));

For some reason . characters before flat or flatMap are optional. This could be changed to ensure that we're only catching those array methods, not other variables, functions, or even comments that include "flat".

My bad @scissorsneedfoodtoo same as #38491 and #38497

@piouson, ah, I didn't notice those other ones. Thanks for bringing this up, though! It's definitely something we want to fix.
