|  | // EXERCISE: Refactor the game store to funcs - step #3 | ||
|  | // | ||
|  | //  Let's continue from the previous exercise. This time, | ||
|  | //  you're going to add json encoding and decoding using | ||
|  | //  funcs. | ||
|  | // | ||
|  | //  1- Create a new command in a func that encodes the | ||
|  | //     game store data to json and terminates the program. | ||
|  | //     Lastly, add it to runCmd func. | ||
|  | // | ||
|  | //     For more information, see: "Encode" exercise from | ||
|  | //     the structs section. | ||
|  | // | ||
|  | //        Name  : cmdSave | ||
|  | //        Inputs: []game | ||
|  | //        Output: bool | ||
|  | // | ||
|  | //  2- Refactor the load() to load the games from the | ||
|  | //     `data` constant (it's in the games.go as well). | ||
|  | // | ||
|  | //     For more information, see: "Decode" exercise from | ||
|  | //     the structs section. | ||
