An example of elegant writing of judgment in JavaScript

const myFunction = (status) => {
  if (status === 1) {
    console.log("status1");
  } else if (status === 2) {
    console.log("status2");
  } else if (status === 3) {
    console.log("status3");
  }
};

//Put the judgment condition into Object const statusObj = {
  1: "status1",
  2: "status2",
  3: "status3",
};

// Optimized function 💎
const myFunction = (status) => {
  console.log(statusObj[status]);
};

//Put the judgment conditions into Map const statusMap = new Map([
  [1, "status1"],
  [2, "status2"],
  [3, "status3"],
]);

// Optimized function 💎
const myFunction = (status) => {
  console.log(statusMap.get(status));
};

// Give an example 🌰
const myFunction = (right, status) => {
  if (right === "administrator" && status === 1) {
    console.log("Administrator likes Wang Bingbing");
  } else if (right === "administrator" && status === 2) {
    console.log("Administrator doesn't like Wang Bingbing");
  } else if (right === "user" && status === 1) {
    console.log("User likes Wang Bingbing");
  } else if (right === "user" && status === 2) {
    console.log("The user doesn't like Wang Bingbing");
  }
};

// Example with duplication 🌰
const myFunction = (right, status) => {
  if (right === "administrator" && status === 1) {
    console.log("Administrator likes Wang Bingbing");
  } else if (right === "administrator" && status === 2) {
    console.log("Administrator likes Wang Bingbing");
  } else if (right === "user" && status === 1) {
    console.log("User likes Wang Bingbing");
  } else if (right === "user" && status === 2) {
    console.log("User likes Wang Bingbing");
  }
};

// Optimize "Example 🌰"

//Put the judgment condition into Object const actionsObj = {
  "administrator-1": "Administrator likes Wang Bingbing",
  "administrator-2": "Administrator doesn't like Wang Bingbing",
  "user-1": "User likes Wang Bingbing",
  "user-2": "The user doesn't like Wang Bingbing",
};

// Optimized function 💎
const myFunction = (right, status) => {
  console.log(actionsObj[`${right}-${status}`]);
};

// You can use the function as "value". The following cases are similar and will not be described in detail.
const actionsObj = {
  "administrator-1": () => console.log("Administrator likes Wang Bingbing"),
  "administrator-2": () => console.log("Administrator likes Wang Bingbing"),
  "user-1": () => console.log("Administrator likes Wang Bingbing"),
  "user-2": () => console.log("Administrator likes Wang Bingbing"),
};

// Optimized function 💎
const myFunction = (right, status) => {
  actionsObj[`${right}-${status}`]();
};

// Optimize "Examples with duplicate situations 🌰"
// Public functions can be extracted. The following situations are similar and will not be repeated 🍓
const actions = () => {
  const f1 = () => console.log("Administrator likes Wang Bingbing");
  const f2 = () => console.log("User likes Wang Bingbing");

  return {
    "administrator-1": f1,
    "administrator-2": f1,
    "user-1": f2,
    "user-2": f2,
  };
};

// Optimized function 💎
const myFunction = (right, status) => {
  actions()[`${right}-${status}`]();
};

// Optimize "Example 🌰"

//Put the judgment conditions into the Map const actionsMap = new Map([
    ['administrator-1', 'Administrator likes Wang Bingbing'],
    ['administrator-2', 'The administrator doesn't like Wang Bingbing'],
    ['user-1', 'User likes Wang Bingbing'],
    ['user-2', 'The user doesn't like Wang Bingbing']
]);

// Optimized function 💎
const myFunction = (right, status) => {
    console.log(actionsMap.get(`${right}-${status}`));
};

// Optimize "Example 🌰"

//Put the judgment conditions into the Map const actionsMap = new Map([
    [{ right: 'administrator', status: 1 }, () => console.log('Administrator likes Wang Bingbing')],
    [{ right: 'administrator', status: 2 }, () => console.log('Administrator doesn't like Wang Bingbing')],
    [{ right: 'user', status: 1 }, () => console.log('User likes Wang Bingbing')],
    [{ right: 'user', status: 2 }, () => console.log('The user doesn't like Wang Bingbing')]
]);

// Optimized function 💎
const myFunction = (right, status) => {
    const action = [...actionsMap].filter(([e]) => (e.right === right && e.status === status));
    action.forEach(([_, index]) => index.call());
};

// Optimize "Examples with duplicate situations 🌰"

// Write the judgment condition as a regular expression and then put it into the Map const actions = () => {
    const f1 = () => console.log('The administrator likes Wang Bingbing');
    const f2 = () => console.log('User likes Wang Bingbing');

    return new Map([
        [/^administrator-[1-2]/, f1],
        [/^user-[1-2]/, f2]
    ]);
};

// Optimized function 💎
const myFunction = (right, status) => {
    const action = [...actions()].filter(([e]) => e.test(`${right}-${status}`));
    action.forEach(([_, index]) => index.call());
};
