--description--
So far, you have only been able to extract or search a pattern once.
let testStr = "Repeat, Repeat, Repeat";
let ourRegex = /Repeat/;
testStr.match(ourRegex);
Here match
would return ["Repeat"]
.
To search or extract a pattern more than once, you can use the global search flag: g
.
let repeatRegex = /Repeat/g;
testStr.match(repeatRegex);
And here match
returns the value ["Repeat", "Repeat", "Repeat"]
--instructions--
Using the regex starRegex
, find and extract both Twinkle
words from the string twinkleStar
.
Note
You can have multiple flags on your regex like /search/gi
--hints--
Your regex starRegex
should use the global flag g
assert(starRegex.flags.match(/g/).length == 1);
Your regex starRegex
should use the case insensitive flag i
assert(starRegex.flags.match(/i/).length == 1);
Your match should match both occurrences of the word Twinkle
assert(
result.sort().join() ==
twinkleStar
.match(/twinkle/gi)
.sort()
.join()
);
Your match result
should have two elements in it.
assert(result.length == 2);
