How does lodash.isNil work?

lodash.isNil is a function that checks if a given value is null or undefined. It returns true if the value is null or undefined, and false otherwise. The function uses the strict equality operator (===) to compare the value with null and undefined.

const _ = require("lodash");

let value1 = null;
let value2 = undefined;
let value3 = "something";

console.log(_.isNil(value1)); // true
console.log(_.isNil(value2)); // true
console.log(_.isNil(value3)); // false

In this example, we first import the lodash library and define three variables: value1 and value2 are set to null and undefined, respectively, while value3 is set to the string "something". We then use _.isNil to check if each of these variables is null or undefined, and log the result to the console. As we can see, _.isNil returns true for both value1 and value2, which are null and undefined, respectively, and false for value3, which is neither null nor undefined.
