--description--

So far, you have only been checking if a pattern exists or not within a string. You can also extract the actual matches you found with the .match() method.

To use the .match() method, apply the method on a string and pass in the regex inside the parentheses.

Here's an example:

"Hello, World!".match(/Hello/);
// Returns ["Hello"]
let ourStr = "Regular expressions";
let ourRegex = /expressions/;
ourStr.match(ourRegex);
// Returns ["expressions"]

Note that the .match syntax is the "opposite" of the .test method you have been using thus far:

'string'.match(/regex/);
/regex/.test('string');

--instructions--

Apply the .match() method to extract the word coding.

--hints--

The result should have the word coding

assert(result.join() === 'coding');

Your regex codingRegex should search for coding

assert(codingRegex.source === 'coding');

You should use the .match() method.

assert(code.match(/\.match\(.*\)/));

--seed-contents--

let extractStr = "Extract the word 'coding' from this string.";
let codingRegex = /change/; // Change this line
let result = extractStr; // Change this line

--solutions--

let extractStr = "Extract the word 'coding' from this string.";
let codingRegex = /coding/; // Change this line
let result = extractStr.match(codingRegex); // Change this line
