--description--
The challenges so far have covered matching letters of the alphabet and numbers. You can also match the whitespace or spaces between letters.
You can search for whitespace using \s
, which is a lowercase s
. This pattern not only matches whitespace, but also carriage return, tab, form feed, and new line characters. You can think of it as similar to the character class [ \r\t\f\n\v]
.
let whiteSpace = "Whitespace. Whitespace everywhere!"
let spaceRegex = /\s/g;
whiteSpace.match(spaceRegex);
This match
call would return [" ", " "]
.
--instructions--
Change the regex countWhiteSpace
to look for multiple whitespace characters in a string.
--hints--
Your regex should use the global flag.
assert(countWhiteSpace.global);
Your regex should use the shorthand character \s
to match all whitespace characters.
assert(/\\s/.test(countWhiteSpace.source));
Your regex should find eight spaces in the string Men are from Mars and women are from Venus.
assert(
'Men are from Mars and women are from Venus.'.match(countWhiteSpace).length ==
8
);
Your regex should find three spaces in the string Space: the final frontier.
assert('Space: the final frontier.'.match(countWhiteSpace).length == 3);
Your regex should find no spaces in the string MindYourPersonalSpace
assert('MindYourPersonalSpace'.match(countWhiteSpace) == null);

let result = sample.match(countWhiteSpace);
