+# mapKeysAsync
+
+Returns a new object with keys transformed through an async function.
+
+```typescript
+const newObj = await mapKeysAsync(object, getNewKey);
+```
+
+## Usage
+
+### `mapKeysAsync(object, getNewKey, options?)`
+
+Use `mapKeysAsync` when you want to create a new object by asynchronously transforming each key. Values remain the same, and only the keys are changed to the resolved results of the `getNewKey` function.
+
+```typescript
+import { mapKeysAsync } from 'es-toolkit/object';
+
+// Add prefix to keys
+const obj = { a: 1, b: 2 };
+const prefixed = await mapKeysAsync(obj, (value, key) => `prefix_${key}`);
+// prefixed becomes { prefix_a: 1, prefix_b: 2 }
+
+// Combine key and value to create new keys
+const combined = await mapKeysAsync(obj, (value, key) => `${key}${value}`);
+// combined becomes { a1: 1, b2: 2 }
+
+// Convert keys to uppercase
+const uppercased = await mapKeysAsync(obj, (value, key) => key.toString().toUpperCase());
+// uppercased becomes { A: 1, B: 2 }
+
+// Limit concurrency.
+await mapKeysAsync(obj, async (value, key) => await processKey(key, value), { concurrency: 2 });
+// Only 2 keys are processed concurrently at most.
+```
+
+#### Parameters
+
+- `object` (`T extends Record<PropertyKey, any>`): The object to transform keys from.
+- `getNewKey` (`(value: T[keyof T], key: keyof T, object: T) => Promise<K>`): An async function that generates new keys. Receives value, key, and the entire object as parameters.
+- `options` (`MapKeysAsyncOptions`, optional): Options to control concurrency.
+  - `concurrency` (`number`, optional): Maximum number of concurrent operations. If not specified, all operations run concurrently.
+
+#### Returns
+
+(`Promise<Record<K, T[keyof T]>>`): A promise that resolves to a new object with transformed keys.

+
+## Usage
+
+### `mapValuesAsync(object, getNewValue, options?)`
+
+Use `mapValuesAsync` when you want to create a new object by asynchronously transforming each value. Keys remain the same, and only the values are changed to the resolved results of the `getNewValue` function.
+
+```typescript
+import { mapValuesAsync } from 'es-toolkit/object';
+
+// Double all values
+const numbers = { a: 1, b: 2, c: 3 };
+const doubled = await mapValuesAsync(numbers, async value => value * 2);
+// doubled becomes { a: 2, b: 4, c: 6 }
+
+// Convert string values to uppercase
+const strings = { first: 'hello', second: 'world' };
+const uppercased = await mapValuesAsync(strings, async value => value.toUpperCase());
+// uppercased becomes { first: 'HELLO', second: 'WORLD' }
+
+// Use both key and value
+const scores = { alice: 85, bob: 90, charlie: 95 };
+const grades = await mapValuesAsync(scores, async (value, key) => `${key}: ${value >= 90 ? 'A' : 'B'}`);
+// grades becomes { alice: 'alice: B', bob: 'bob: A', charlie: 'charlie: A' }

+const items = { a: 1, b: 2, c: 3 };
+await mapValuesAsync(items, async item => await processItem(item), { concurrency: 2 });
+// Only 2 values are processed concurrently at most.
+```
+
+#### Parameters
+
+- `object` (`T extends object`): The object to transform values from.
+- `getNewValue` (`(value: T[K], key: K, object: T) => Promise<V>`): An async function that generates new values. Receives value, key, and the entire object as parameters.
+- `options` (`MapValuesAsyncOptions`, optional): Options to control concurrency.
+  - `concurrency` (`number`, optional): Maximum number of concurrent operations. If not specified, all operations run concurrently.
+

+
+## 用法
+
+### `mapKeysAsync(object, getNewKey, options?)`
+
+当您想要通过异步转换每个键来创建新对象时使用`mapKeysAsync`。值保持不变,只有键会更改为`getNewKey`函数的解析结果。
+
+```typescript
+import { mapKeysAsync } from 'es-toolkit/object';
+
+// 为键添加前缀
+const obj = { a: 1, b: 2 };
+const prefixed = await mapKeysAsync(obj, (value, key) => `prefix_${key}`);
+// prefixed 变为 { prefix_a: 1, prefix_b: 2 }
+
+// 组合键和值来创建新键
+const combined = await mapKeysAsync(obj, (value, key) => `${key}${value}`);
+// combined 变为 { a1: 1, b2: 2 }
+
+// 将键转换为大写
+const uppercased = await mapKeysAsync(obj, (value, key) => key.toString().toUpperCase());
+// uppercased 变为 { A: 1, B: 2 }
+
+// 限制并发数
+await mapKeysAsync(obj, async (value, key) => await processKey(key, value), { concurrency: 2 });
+// 最多同时处理2个键
+```
+
+#### 参数
+
+- `object` (`T extends Record<PropertyKey, any>`): 要转换键的源对象。
+- `getNewKey` (`(value: T[keyof T], key: keyof T, object: T) => Promise<K>`): 生成新键的异步函数。接收值、键和整个对象作为参数。
