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

The isFinite function from the Underscore library in JavaScript is used to determine whether a given value is a finite number or not. It returns a boolean value indicating if the value is a finite number.

Here's an example code snippet showing how to use the isFinite function from the Underscore library:

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

const num1 = 5;
const num2 = NaN;

console.log(_.isFinite(num1)); // true
console.log(_.isFinite(num2)); // false

In the code above, we first import the Underscore library using the require statement. Then, we define two variables num1 and num2 with a finite number and NaN value respectively. We use the _.isFinite function from the Underscore library to check if both variables represent finite numbers, and log the results to the console.
