how to use the isnil function from lodash in javascript

To use the isNil function from lodash in JavaScript, you must first install lodash in your project using npm or yarn:

npm install lodash
19 chars
2 lines

Or

yarn add lodash
16 chars
2 lines

Then, in your JavaScript file, import the isNil function from lodash and call it with a value as the parameter. It will return true if the value is either null or undefined, and false otherwise. Here's an example:

index.tsx
import { isNil } from 'lodash';

const value1 = null;
const value2 = undefined;
const value3 = 'something';

console.log(isNil(value1));
// Output: true

console.log(isNil(value2));
// Output: true

console.log(isNil(value3));
// Output: false

In the above example, we first imported the isNil function from lodash. We then created three variables value1, value2 and value3, and called the isNil function with each of them. The output shows that isNil returned true for value1 and value2, and false for value3.
