--description--

Given an array of playing cards, return a new array with the numeric value of each card.

Card Values:

• An Ace ("A") has a value of 1.
• Numbered cards ("2" - "10") have their face value: 2 - 10, respectively.
• Face cards: Jack ("J"), Queen ("Q"), and King ("K") are each worth 10.

Suits:

• Each card has a suit: Spades ("S"), Clubs ("C"), Diamonds ("D"), or Hearts ("H").

Card Format:

• Each card is represented as a string: "valueSuit". For Example: "AS" is the Ace of Spades, "10H" is the Ten of Hearts, and "QC" is the Queen of Clubs.

--hints--

cardValues(["3H", "4D", "5S"]) should return [3, 4, 5].

assert.deepEqual(cardValues(["3H", "4D", "5S"]), [3, 4, 5]);

cardValues(["AS", "10S", "10H", "6D", "7D"]) should return [1, 10, 10, 6, 7].

assert.deepEqual(cardValues(["AS", "10S", "10H", "6D", "7D"]), [1, 10, 10, 6, 7]);

cardValues(["8D", "QS", "2H", "JC", "9C"]) should return [8, 10, 2, 10, 9].

assert.deepEqual(cardValues(["8D", "QS", "2H", "JC", "9C"]), [8, 10, 2, 10, 9]);

cardValues(["AS", "KS"]) should return [1, 10].

assert.deepEqual(cardValues(["AS", "KS"]), [1, 10]);

cardValues(["10H", "JH", "QH", "KH", "AH"]) should return [10, 10, 10, 10, 1].

assert.deepEqual(cardValues(["10H", "JH", "QH", "KH", "AH"]), [10, 10, 10, 10, 1]);
