--description--

Given a string of a valid HTML element, return the attributes of the element using the following criteria:

• You will only be given one element.
• Attributes will be in the format: attribute="value".
• Return an array of strings with each attribute property and value, separated by a comma, in this format: ["attribute1, value1", "attribute2, value2"].
• Return attributes in the order they are given.
• If no attributes are found, return an empty array.

--hints--

extractAttributes('<span class="red"></span>') should return ["class, red"].

assert.deepEqual(extractAttributes('<span class="red"></span>'), ["class, red"]);

extractAttributes('<meta charset="UTF-8" />') should return ["charset, UTF-8"].

assert.deepEqual(extractAttributes('<meta charset="UTF-8" />'), ["charset, UTF-8"]);

extractAttributes("<p>Lorem ipsum dolor sit amet</p>") should return [].

assert.deepEqual(extractAttributes("<p>Lorem ipsum dolor sit amet</p>"), []);

extractAttributes('<input name="email" type="email" required="true" />') should return ["name, email", "type, email", "required, true"].

assert.deepEqual(extractAttributes('<input name="email" type="email" required="true" />'), ["name, email", "type, email", "required, true"]);

extractAttributes('<button id="submit" class="btn btn-primary">Submit</button>') should return ["id, submit", "class, btn btn-primary"].

assert.deepEqual(extractAttributes('<button id="submit" class="btn btn-primary">Submit</button>'), ["id, submit", "class, btn btn-primary"]);
