To use the isElement function from the Underscore library in TypeScript, we first need to install the Underscore library and its type definitions using npm:

index.ts
npm install underscore @types/underscore

2 lines

Once installed, we can import the isElement function and use it as follows:

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

const myElement = document.createElement('div');
const isMyElement = _.isElement(myElement);

console.log(isMyElement); // true

In the above code, we imported the entire Underscore library as _, created a DOM element using document.createElement, and then used the isElement function to check if the element we created is a valid DOM element. The function returns a boolean value indicating whether the provided object is a DOM element or not.
