--description--
In the last challenge, you searched for the word "Hello"
using the regular expression /Hello/
. That regex searched for a literal match of the string "Hello"
. Here's another example searching for a literal match of the string "Kevin"
:
let testStr = "Hello, my name is Kevin.";
let testRegex = /Kevin/;
testRegex.test(testStr);
// Returns true
Any other forms of "Kevin"
will not match. For example, the regex /Kevin/
will not match "kevin"
or "KEVIN"
.
let wrongRegex = /kevin/;
wrongRegex.test(testStr);
// Returns false
A future challenge will show how to match those other forms as well.
--instructions--
Complete the regex waldoRegex
to find "Waldo"
in the string waldoIsHiding
with a literal match.
--hints--
Your regex waldoRegex
should find "Waldo"
assert(waldoRegex.test(waldoIsHiding));
Your regex waldoRegex
should not search for anything else.
assert(!waldoRegex.test('Somewhere is hiding in this text.'));
You should perform a literal string match with your regex.
assert(!/\/.*\/i/.test(code));

let waldoIsHiding = "Somewhere Waldo is hiding in this text.";
let waldoRegex = /search/; // Change this line
let result = waldoRegex.test(waldoIsHiding);
--solutions--
let waldoIsHiding = "Somewhere Waldo is hiding in this text.";
let waldoRegex = /Waldo/; // Change this line
let result = waldoRegex.test(waldoIsHiding);
