actually-this-is-a-number's Issues
breaks on any value other than a string
The following statement should return a number:
actuallyThisIsANumber(10000);
(because, actually, 10000
IS a number) ๐
but instead returns:
TypeError: undefined is not a function
The error is happening because you are attempting to run the replace()
method on a number, but the replace()
method is only available to string objects.
Along these same lines, you get the same error if you attempt to pass anything other than a string:
actuallyThisIsANumber({});
//=> TypeError: undefined is not a function
So a simple check/throw could be nice, because if it's going throw an error anyway, it might as well throw something useful to developers:
TypeError: actually-this-is-a-number expects a string
