--- id: 587d7db8367417b2b2512ba0 title: Match Everything But Letters and Numbers challengeType: 1 --- ## Description
You've learned that you can use a shortcut to match alphanumerics [A-Za-z0-9_] using \w. A natural pattern you might want to search for is the opposite of alphanumerics. You can search for the opposite of the \w with \W. Note, the opposite pattern uses a capital letter. This shortcut is the same as [^A-Za-z0-9_].
let shortHand = /\W/;
let numbers = "42%";
let sentence = "Coding!";
numbers.match(shortHand); // Returns ["%"]
sentence.match(shortHand); // Returns ["!"]
## Instructions
Use the shorthand character class \W to count the number of non-alphanumeric characters in various quotes and strings.
## Tests
```yml tests: - text: Your regex should use the global flag. testString: 'assert(nonAlphabetRegex.global, "Your regex should use the global flag.");' - text: Your regex should find 6 non-alphanumeric characters in "The five boxing wizards jump quickly.". testString: 'assert("The five boxing wizards jump quickly.".match(nonAlphabetRegex).length == 6, "Your regex should find 6 non-alphanumeric characters in "The five boxing wizards jump quickly.".");' - text: Your regex should use the shorthand character. testString: 'assert(/\\W/.test(nonAlphabetRegex.source), "Your regex should use the shorthand character to match characters which are non-alphanumeric.");' - text: Your regex should find 8 non-alphanumeric characters in "Pack my box with five dozen liquor jugs." testString: 'assert("Pack my box with five dozen liquor jugs.".match(nonAlphabetRegex).length == 8, "Your regex should find 8 non-alphanumeric characters in "Pack my box with five dozen liquor jugs."");' - text: Your regex should find 6 non-alphanumeric characters in "How vexingly quick daft zebras jump!" testString: 'assert("How vexingly quick daft zebras jump!".match(nonAlphabetRegex).length == 6, "Your regex should find 6 non-alphanumeric characters in "How vexingly quick daft zebras jump!"");' - text: Your regex should find 12 non-alphanumeric characters in "123 456 7890 ABC def GHI jkl MNO pqr STU vwx YZ." testString: 'assert("123 456 7890 ABC def GHI jkl MNO pqr STU vwx YZ.".match(nonAlphabetRegex).length == 12, "Your regex should find 12 non-alphanumeric characters in "123 456 7890 ABC def GHI jkl MNO pqr STU vwx YZ."");' ```
## Challenge Seed
