 You should assign an array of the strings `"London"`, `"New York"`, and `"Mumbai"` to the `cities` variable.
 
 ```js
-assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*\]/);
+assert.match(code, /let\s+cities\s*=\s*\[\s*("|'|`)London\1\s*,\s*("|'|`)New York\2\s*,\s*("|'|`)Mumbai\3\s*,?\s*\]/);
 ```
 
 You should use `console.log()` to log the entire `cities` array to the console.
