587d7db3367417b2b2512b8f	Match Literal Strings	1

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.

Tests

tests:
  - text: Your regex <code>waldoRegex</code> should find <code>"Waldo"</code>
    testString: assert(waldoRegex.test(waldoIsHiding), 'Your regex <code>waldoRegex</code> should find <code>"Waldo"</code>');
  - text: Your regex <code>waldoRegex</code> should not search for anything else.
    testString: assert(!waldoRegex.test('Somewhere is hiding in this text.'), 'Your regex <code>waldoRegex</code> should not search for anything else.');
  - text: You should perform a literal string match with your regex.
    testString: assert(!/\/.*\/i/.test(code), 'You should perform a literal string match with your regex.');
