Javascript如何从map返回数组

const myMap = new Map();
myMap.set(1, 'one');
myMap.set(2, 'two');
myMap.set(3, 'three');

const myArray = Array.from(myMap);

console.log(myArray);

[
  [1, 'one'],
  [2, 'two'],
  [3, 'three']
]

const myMap = new Map();
myMap.set(1, 'one');
myMap.set(2, 'two');
myMap.set(3, 'three');

const keysArray = Array.from(myMap.keys());

console.log(keysArray);

[1, 2, 3]
