// 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.
