如何将switch语句遍历对象优化的更精简

switch (this.active) {
    case 0:
      this.OrderState = 'Wait';
      break;
    case 1:
      this.OrderState = 'Sent';
      break;
    case 2:
      this.OrderState = 'Fail';
      break;
    default:
      break;
}

Answer 1

const temp = ['wait', 'Sent', 'Fail'];
this.OrderState = temp[this.active]

Answer 2

2019年了，肯定玩点骚操作啊，用Map来表示映射关系。

let stateMap = new Map

stateMap
    .set(0, 'Wait')
    .set(1, 'Sent')
    .set(2, 'Fail')
    
this.OrderState = stateMap.get(this.active)
