--description--

The locations array contains two locations: the town square and store. Currently the entire array with both locations is being passed in to the update function. Pass in only the first element of the locations array by adding [0] at the end of the name of the array. For example, exampleFunction(arg[0]);

--hints--

See description above for instructions.

assert(goTown.toString().match(/update\(locations\[0\]\)/));
