how to use the keys function from the lodash library in typescript

To use the keys function from the Lodash library in TypeScript, you need to import it from the library and provide the proper type definitions.

Here's an example of how to do it:

1. First, install the Lodash library using NPM:

index.ts
npm install lodash
19 chars
2 lines

2. Import the keys function from the library:

index.ts
import { keys } from 'lodash';
31 chars
2 lines

3. Define the type of the object you want to get the keys from:

index.ts
interface MyObject {
  foo: string;
  bar: number;
  baz: boolean;
}
69 chars
6 lines

4. Call the keys function, passing the object as an argument:

index.ts
const obj: MyObject = { foo: 'hello', bar: 42, baz: true };
const keysArray: Array<keyof MyObject> = keys(obj);
112 chars
3 lines

Here, we specified that the resulting array will contain keys of the MyObject type by using keyof MyObject. This provides better type checking and avoids the need to cast the resulting array to the correct type.

Note that you'll need to have the proper type definitions for the Lodash library installed (you can install them using NPM with npm install @types/lodash).
