js中map获取所有对象

const myMap = new Map();
myMap.set('key1', 'value1');
myMap.set('key2', { obj: 'value2' });
myMap.set({ key3: 'value3' }, 'value4');

const keys = Array.from(myMap.keys());
console.log(keys); // ['key1', 'key2', { key3: 'value3' }]

const values = Array.from(myMap.values());
console.log(values); // ['value1', { obj: 'value2' }, 'value4']

const entries = Array.from(myMap.entries());
console.log(entries); 
// [['key1', 'value1'], ['key2', { obj: 'value2' }], [{ key3: 'value3' }, 'value4']]

for (const [key, value] of myMap) {
  console.log(key, value);
}

myMap.forEach((value, key) => {
  console.log(key, value);
});

const myMap = new Map();

// 添加键值对
myMap.set('name', 'Alice');
myMap.set('age', 30);
myMap.set({ id: 1 }, 'objectKey');

// 获取所有的键
const keys = Array.from(myMap.keys());
console.log('Keys:', keys);

// 获取所有的值
const values = Array.from(myMap.values());
console.log('Values:', values);

// 遍历 Map
console.log('Entries:');
for (const [key, value] of myMap) {
  console.log(key, value);
}
