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

ismap is a function provided by the Underscore.js library that returns a boolean indicating whether the input value is a map (an object with key-value pairs) or not.

Here's an example usage of ismap:

index.tsx
const _ = require('underscore');

const myObj = { a: 1, b: 2, c: 3 };
const myArr = [1, 2, 3];

console.log(_.ismap(myObj)); // true
console.log(_.ismap(myArr)); // false

In the code above, we first import Underscore using require. We then define two variables, myObj and myArr, one being an object with key-value pairs, and the other an array. Finally, we pass each variable as an argument to _.ismap and log the results.
