We can also use regular expression selectors like \s to find whitespace in a string.
The whitespace characters are " " (space), \r (the carriage return), \n (newline), \t (tab), and \f (the form feed).
The whitespace regular expression looks like this:
Instructions Use \s to select all the whitespace characters in the sentence string.
// Setup var testString = "How many spaces are there in this sentence?"; // Only change code below this line. var expression = /\s+/g; // Change this line // Only change code above this line // This code counts the matches of expression in testString var spaceCount = testString.match(expression).length;
