What are is-finite's main functionalities?

Check if a value is finite

This feature allows you to check if a given value is a finite number. The code sample demonstrates checking various values, including a finite number, Infinity, and a string.

const isFinite = require('is-finite');

console.log(isFinite(10)); // true
console.log(isFinite(Infinity)); // false
console.log(isFinite('10')); // false

Other packages similar to is-finite

is-number

The is-number package checks if a value is a number, which includes both finite and infinite numbers. It provides a broader check compared to is-finite, which only checks for finite numbers.

lodash.isfinite

The lodash.isfinite package is a part of the Lodash library that provides a similar functionality to is-finite. It checks if a value is a finite number, but it is part of a larger utility library, making it useful if you need additional functionalities provided by Lodash.

is-finite-x

The is-finite-x package is another alternative that checks if a value is a finite number. It is similar to is-finite but may have different implementation details or additional features.
