how to use the isobject function from the underscore library in javascript

To use the isobject function from the underscore library in JavaScript, you need to follow these steps:

  1. First, you need to include the underscore library in your project, either by downloading it and referencing it in your HTML or including it as a dependency if you're using a package manager like npm.

  2. Once you've included the library, you can use the _.isObject() method to check if a variable is an object. Here's an example:

index.tsx
// Import the underscore library
const _ = require('underscore');

// Define some variables
const obj = {a: 1, b: 2};
const arr = [1, 2, 3];

// Check if the variables are objects
console.log(_.isObject(obj)); // true
console.log(_.isObject(arr)); // true
console.log(_.isObject('hello')); // false
console.log(_.isObject(null)); // false

In the above code, we imported the underscore library and defined some variables. We then used the _.isObject() method to check if the variables are objects. The method returns a boolean value indicating whether the variable is an object or not.

Note that the _.isObject() method returns true for arrays because arrays are a special type of object in JavaScript. If you want to check specifically for an object and not an array, you can use the _.isPlainObject() method instead.
