jsSwitch语句优化

// Longhand
switch (data) {
    case 1:
        data1();
        break;
    case 2:
        data2();
        break;
    case 3:
        data();
        break;
        // And so on...
}
// Shorthand
var data = {
    1: data1,
    2: data2,
    3: data
};
const val = 1
data[val]();
function data1() {
    console.log("data1");
}
function data2() {
    console.log("data2");
}
function data() {
    console.log("data");
}
