Lodash _.isFinite


The lodash _.isFinite method is a function that allows you to determine whether a given value is a finite number. It returns a boolean value that is true if the value is finite and false if it is not.

This method works by checking whether the value is a number and is finite. If the value is not a number, it will return false. If the value is a number but is not finite (e.g. it is NaN or infinite), it will also return false. Otherwise, it will return true.

The _.isFinite method is a part of the lodash library, which is a popular JavaScript utility library that provides many useful functions for working with arrays, objects, and other data structures in JavaScript. It is often used in conjunction with other lodash methods for various tasks, such as filtering arrays, mapping objects, and more.

Here is an example of using the _.isFinite method:

const num1 = 10;
const num2 = Infinity;
const num3 = "hello";

_.isFinite(num1); // true
_.isFinite(num2); // false
_.isFinite(num3); // false

In this example, num1 is a finite number, so _.isFinite(num1) returns true. num2 is not a finite number (it is infinite), so _.isFinite(num2) returns false. num3 is not a number at all, so _.isFinite(num3) returns false.

Overall, the _.isFinite method can be a useful tool in your JavaScript development toolkit for checking whether a value is a finite number.
