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

To use the functions function from the lodash library in Typescript, you first need to import it from the library. Then, you can use it in your code by passing in an object as its argument.

Here's an example:

index.ts
import { functions } from 'lodash';

interface MyInterface {
  prop1: string,
  prop2: number,
  myFunc: () => void,
}

const myObj: MyInterface = {
  prop1: 'Hello',
  prop2: 42,
  myFunc: () => { console.log('Hello from myFunc'); },
};

const myObjFuncNames: string[] = functions(myObj);
console.log(myObjFuncNames); // Logs ['myFunc']
338 chars
17 lines

In this example, we have an interface MyInterface with three properties - prop1, prop2, and myFunc. We create an object of type MyInterface called myObj.

We import the functions function from the lodash library and call it with myObj as its argument. This returns an array of strings containing the names of all the functions defined on myObj.

We use type annotations throughout to ensure that our code is correctly typed.
