--description--
Sometimes you won't (or don't need to) know the exact characters in your patterns. Thinking of all words that match, say, a misspelling would take a long time. Luckily, you can save time using the wildcard character: .
The wildcard character .
will match any one character. The wildcard is also called dot
and period
. You can use the wildcard character just like any other character in the regex. For example, if you wanted to match hug
, huh
, hut
, and hum
, you can use the regex /hu./
to match all four words.
let humStr = "I'll hum a song";
let hugStr = "Bear hug";
let huRegex = /hu./;
huRegex.test(humStr);
huRegex.test(hugStr);
Both of these test
calls would return true
.
--instructions--
Complete the regex unRegex
so that it matches the strings run
, sun
, fun
, pun
, nun
, and bun
. Your regex should use the wildcard character.
--hints--
You should use the .test()
method.
assert(__helpers.removeJSComments(code).match(/\.test\(.*\)/));
You should use the wildcard character in your regex unRegex
assert(/\./.test(unRegex.source));
Your regex unRegex
should match run
in the string Let us go on a run.
unRegex.lastIndex = 0;
assert(unRegex.test('Let us go on a run.'));
Your regex unRegex
should match sun
in the string The sun is out today.
unRegex.lastIndex = 0;
assert(unRegex.test('The sun is out today.'));
Your regex unRegex
should match fun

unRegex.lastIndex = 0;
assert(unRegex.test('Coding is a lot of fun.'));
Your regex unRegex
should match pun

unRegex.lastIndex = 0;
assert(unRegex.test('Seven days without a pun makes one weak.'));

unRegex.lastIndex = 0;
assert(unRegex.test('One takes a vow to be a nun.'));
Your regex unRegex

unRegex.lastIndex = 0;
assert(
unRegex.test(
'She got fired from the hot dog stand for putting her hair in a bun.'
)
);
Your regex unRegex
should not match the string There is a bug in my code.
unRegex.lastIndex = 0;
assert(!unRegex.test('There is a bug in my code.'));
