js有没有equals方法

class Person {
  constructor(name, age) {
    this.name = name;
    this.age = age;
  }

  equals(other) {
    if (other === null || typeof other !== 'object') {
      return false;
    }
    return this.name === other.name && this.age === other.age;
  }
}

const person1 = new Person('Alice', 30);
const person2 = new Person('Alice', 30);
const person3 = new Person('Bob', 25);

console.log(person1.equals(person2)); // true
console.log(person1.equals(person3)); // false

const _ = require('lodash');

const obj1 = { a: 1, b: { c: 2 } };
const obj2 = { a: 1, b: { c: 2 } };

console.log(_.isEqual(obj1, obj2)); // true
