如何组合两个对象元素

const obj1 = { name: 'Alice', age: 25 };
const obj2 = { gender: 'female', occupation: 'engineer' };

// 使用Object.assign()方法
const mergedObj = Object.assign({}, obj1, obj2);
console.log(mergedObj); // { name: 'Alice', age: 25, gender: 'female', occupation: 'engineer' }

// 使用展开运算符
const mergedObj2 = { ...obj1, ...obj2 };
console.log(mergedObj2); // { name: 'Alice', age: 25, gender: 'female', occupation: 'engineer' }

const obj1 = { fruits: ['apple', 'banana'] };
const obj2 = { fruits: ['orange', 'grape'] };

// 使用concat()方法
const mergedObj = { fruits: obj1.fruits.concat(obj2.fruits) };
console.log(mergedObj); // { fruits: ['apple', 'banana', 'orange', 'grape'] }

// 使用展开运算符
const mergedObj2 = { fruits: [...obj1.fruits, ...obj2.fruits] };
console.log(mergedObj2); // { fruits: ['apple', 'banana', 'orange', 'grape'] }

const obj1 = { sayHello: function() { console.log('Hello!'); } };
const obj2 = { sayGoodbye: function() { console.log('Goodbye!'); } };

// 使用Object.assign()方法
const mergedObj = Object.assign({}, obj1, obj2);
console.log(mergedObj); // { sayHello: [Function: sayHello], sayGoodbye: [Function: sayGoodbye] }

// 使用展开运算符
const mergedObj2 = { ...obj1, ...obj2 };
console.log(mergedObj2); // { sayHello: [Function: sayHello], sayGoodbye: [Function: sayGoodbye] }
