对typescript、node和babel使用静态属性

class MyClass {
  static myStaticProperty: string = "Hello, world!";

  static myStaticMethod() {
    console.log("This is a static method.");
  }
}

console.log(MyClass.myStaticProperty); // 输出: Hello, world!
MyClass.myStaticMethod(); // 输出: This is a static method.

// myModule.js
class MyClass {
  static myStaticProperty = "Hello, world!";

  static myStaticMethod() {
    console.log("This is a static method.");
  }
}

module.exports = MyClass;

// main.js
const MyClass = require("./myModule");

console.log(MyClass.myStaticProperty); // 输出: Hello, world!
MyClass.myStaticMethod(); // 输出: This is a static method.

npm install --save-dev @babel/plugin-proposal-class-properties

{
  "plugins": ["@babel/plugin-proposal-class-properties"]
}

class MyClass {
  static myStaticProperty = "Hello, world!";

  static myStaticMethod() {
    console.log("This is a static method.");
  }
}

console.log(MyClass.myStaticProperty); // 输出: Hello, world!
MyClass.myStaticMethod(); // 输出: This is a static method.
