How does lodash.isObject work?

lodash.isObject is a method provided by the Lodash library which determines whether a given value is an object or not by checking if it is not null, and its type is 'object', 'function' or 'array'.

* @category Objects
* @param {*} value The value to check.
* @returns {boolean} Returns `true` if the `value` is an object, else `false`.
* @example
*
* _.isObject({});

const _ = require("lodash");

console.log(_.isObject({})); // true
console.log(_.isObject({ key: "value" })); // true
console.log(_.isObject([])); // false
console.log(_.isObject("string")); // false
console.log(_.isObject(123)); // false
console.log(_.isObject(null)); // false
console.log(_.isObject(undefined)); // false

In this example, we are using lodash.isObject to check if a value is an object. We pass different values as arguments to _.isObject and check if it returns true or false. The function returns true if the value is an object, and false otherwise.
