¥There is an error with how a function is called. More arguments need to be provided.

示例

¥Examples

未提供必需的参数

¥Required arguments not provided

Object.create() 方法需要至少一个参数，Object.setPrototypeOf() 方法需要至少两个参数：

¥The Object.create() method requires at least one argument and the Object.setPrototypeOf() method requires at least two arguments:

js
const obj = Object.create();
// TypeError: Object.create requires at least 1 argument, but only 0 were passed

const obj2 = Object.setPrototypeOf({});
// TypeError: Object.setPrototypeOf requires at least 2 arguments, but only 1 were passed

你可以通过将 null 设置为原型来解决此问题，例如：

¥You can fix this by setting null as the prototype, for example:

js
const obj = Object.create(null);

const obj2 = Object.setPrototypeOf({}, null);
