refactor(isCreditCard): create allCards dynamically and get rid of hard-to-maintain hardcoded version#2117
Conversation
get rid of the hardcoded allCards variable, which was a manual copy of the existing regExp for card provider. Replace it with a dynamically created array instead, which will make it easier to maintain, when new providers are added.

Why is this if-statement needed?

I originally did not have it in there either, but there is an linting rule that forced me to add it :-)
It otherwise threw me guard-for-in error

Interesting that we are doing this... i would have to look back, but i think that i had a similar solution to this in the first refactor I did. Glad it is coming back, makes maintenance much easier. Any card provider can be added very easily now. |

Hello,
I've refactored the way the
allCardsvariable is created/handled in isCreditCard:It currently is manually hardcoding all of the previously already defined RegExp into one huge RegExp, that it later then checks against.
This is problematic, because:
allCardsI've replace it with a dynamically created array with the RegExps from the
cardsobject instead, which will make it a lot easier to maintain and update, when new providers are added:cardsobjectSince we are now working with an array instead of one huge RegExp, I had to also change the last "else if":
There I am using the Array some() method, which checks if any of the items inside the array return true for a given function.
