how to use the isequal function from the underscore library in typescript

To use the isequal function from the Underscore library in TypeScript, you first need to install the library using a package manager such as npm. You can install Underscore by running the following command in your project directory:

npm install underscore

Once you have installed Underscore, you can import the library and use the isequal function as follows:

index.ts
import * as _ from 'underscore';

const object1 = {a: 1, b: 2, c: 3};
const object2 = {a: 1, b: 2, c: 3};
const result = _.isEqual(object1, object2);

console.log(result); // true

In the example above, we import the Underscore library using the wildcard notation * as _. This imports all the functions in the library and assigns them to the variable _. We then define two objects object1 and object2 with the same keys and values, and use the isEqual function from Underscore to compare the two objects. The result of the comparison is true, since the two objects have the same keys and values.

Note that the isEqual function performs a deep comparison of the values in the objects, so it is suitable for comparing complex objects with nested data structures.
