Refactoring some code

Work on refactoring some javascript.

Before:

const MyFunction = function (key) {
                        if (key) {
                            switch (key) {
                                case "ABC":
                                    return "Info 1";
                                case "DEF":
                                    return "Info 2";
                                case "GHI":
                                    return "Info 3";
                                case "JKL":
                                    return "Info 4";
                                case "MNO":
                                    return "Info 5";
                            }
                        }
                        return "";
                    };

After

const MyFunction = function (key) {
                        const data = {
                                        "ABC": "Info 1",
                                        "DEF": "Info 2",
                                        "GHI": "Info 3",
                                        "JKL": "Info 4",
                                        "MNO": "Info 5"
                                     };
                        return data[key];
                    };

Sweet~!
