--- id: 587d7db9367417b2b2512ba4 title: Match Non-Whitespace Characters challengeType: 1 forumTopicId: 18210 dashedName: match-non-whitespace-characters --- # --description-- You learned about searching for whitespace using `\s`, with a lowercase `s`. You can also search for everything except whitespace. Search for non-whitespace using `\S`, which is an uppercase `s`. This pattern will not match whitespace, carriage return, tab, form feed, and new line characters. You can think of it being similar to the character class `[^ \r\t\f\n\v]`. ```js let whiteSpace = "Whitespace. Whitespace everywhere!" let nonSpaceRegex = /\S/g; whiteSpace.match(nonSpaceRegex).length; ``` The value returned by the `.length` method would be `32`. # --instructions-- Change the regex `countNonWhiteSpace` to look for multiple non-whitespace characters in a string. # --hints-- Your regex should use the global flag. ```js assert(countNonWhiteSpace.global); ``` Your regex should use the shorthand character `\S` to match all non-whitespace characters. ```js assert(/\\S/.test(countNonWhiteSpace.source)); ``` Your regex should find 35 non-spaces in the string `Men are from Mars and women are from Venus.` ```js assert( 'Men are from Mars and women are from Venus.'.match(countNonWhiteSpace) .length == 35 ); ``` Your regex should find 23 non-spaces in the string `Space: the final frontier.` ```js assert('Space: the final frontier.'.match(countNonWhiteSpace).length == 23); ``` Your regex should find 21 non-spaces in the string `MindYourPersonalSpace` ```js assert('MindYourPersonalSpace'.match(countNonWhiteSpace).length == 21); ``` # --seed-- ## --seed-contents-- ```js let sample = "Whitespace is important in separating words"; let countNonWhiteSpace = /change/; // Change this line let result = sample.match(countNonWhiteSpace); ``` # --solutions-- ```js let sample = "Whitespace is important in separating words"; let countNonWhiteSpace = /\S/g; // Change this line let result = sample.match(countNonWhiteSpace); ```
