Each forum post will include a list of user avatar images which represent all of the users participating in the conversation for that topic.

Start by creating an arrow function called avatars, with two parameters called posters and users.

--hints--

You should have an empty arrow function called avatars.

assert.match(code, /const\s+avatars\s*=\s*\([\s\S]*\)\s*=>\s*{\s*}/);

You should have the parameters named posters and users in the function named avatars.

assert.match(code, /const\s+avatars\s*=\s*\(\s*(posters|users)\s*,\s*(posters|users)\s*\)\s*=>\s*{\s*}/);
