}
Returns a list of US state capitals in alphabetical order according to state name.

## Notes

-   This function synchronously reads data from disk for each invocation. Such behavior is intentional and so is the avoidance of `require`. We assume that invocations are infrequent, and we want to avoid the `require` cache. This means that we allow data to be garbage collected and a user is responsible for explicitly caching data.

@throws {Error} unable to read data
@returns {StringArray} capitals

@example
var data = capitals();
// returns [ 'Montgomery', 'Juneau', 'Phoenix', 'Little Rock', ... ]
