如何循环遍历对象数组，将键推送到另一个数组

const originalArray = [
  { key: "key1", value: "value1" },
  { key: "key2", value: "value2" },
  { key: "key3", value: "value3" }
];

const keysArray = [];

for (let i = 0; i < originalArray.length; i++) {
  keysArray.push(originalArray[i].key);
}

console.log(keysArray);

original_array = [
    { "key": "key1", "value": "value1" },
    { "key": "key2", "value": "value2" },
    { "key": "key3", "value": "value3" }
]

keys_array = []

for obj in original_array:
    keys_array.append(obj["key"])

print(keys_array)
