Counting Cards Solution #3

[gekasam94]

Hi!

Did I understand correctly that the third solution used a trick with type coercion? 10 is compared to “10” converted to num, and JQKA is equated to “10” like a string?

freeCodeCamp Challenge Guide: Counting Cards

Counting Cards Hints Hint 1 Use a switch (or else if) statement to count the value of each card. Hint 2 Add/subtract the value of each card to variable count. If the card is worth 0, don’t do anything. Hint 3 After you’ve counted the cards, use an if statement to check the value of count. Also, make sure your return has a space between the number and the string. Solutions

let count = 0; function cc(card) { // Only change code below this line switch…

I don’t see any type coercion in the third solution.
Which line of code are you reading?

Edit: I think you are asking about the string comparison card >= “10”
So this returns true if the lexicographical order of the string in card is greater than it equal to the string “10”.
It just so happens that all alphabetical letters will be considered as “higher” than “10”. So that is how this works.

Thanks, the explanation was easier. But still, it’s a small trick to use encoding properties in this way.

yes you have to know about the ascii table order
