To use the propertyIsEnumerable function from the fs-extra library in TypeScript, follow the steps below:

  1. First, make sure that you have installed the @types/fs-extra package by running the following command:
index.ts
npm install @types/fs-extra --save-dev

  1. Import the fs-extra library in your TypeScript file:
index.ts
import * as fs from 'fs-extra';

  1. Use the propertyIsEnumerable function from the fs-extra library to determine whether an object has the specified property as a direct property of that object:
index.ts
const myObject = { name: 'John', age: 25 };
console.log(fs.propertyIsEnumerable(myObject, 'name')); // true
console.log(fs.propertyIsEnumerable(myObject, 'toString')); // false

4 lines

The first console.log statement returns true because the myObject has the name property and it is enumerable. The second console.log statement returns false because the myObject object does not have the toString property as a direct property.

Note: This function is particularly useful for checking whether an object has an own property defined on itself, as opposed to inheriting it from its prototype chain.
