vue3 ts 不使用 if switch 来决定使用什么函数

const handleOperation = (icon: string) => {

  const handleSetting = () => {
    console.log("handleSetting");
  };

  const handleDataAnalysis = () => {
    console.log("handleDataAnalysis");
  };

  const handlers: { [key: string]: () => void } = {
    "Setting": handleSetting,
    "DataAnalysis": handleDataAnalysis
  };

  const handler = handlers[icon];
  handler ? handler() : (() => {
    throw new Error("No handler found for icon: " + icon);
  })();

};
