--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/);
let ourStr = "Regular expressions";
let ourRegex = /expressions/;
ourStr.match(ourRegex);
Here the first match
would return ["Hello"]
and the second would return ["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 string coding
.
--hints--
The result
should have the string coding
assert(result.join() === 'coding');
Your regex codingRegex
should search for the string coding
assert(codingRegex.source === 'coding');
You should use the .match()
method.
assert(code.match(/\.match\(.*\)/));

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
