--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);

This test call will return 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);

This test call will return 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 the string 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));

--seed--

--seed-contents--

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);
