In this example, lodash.isFinite is used to determine if a given value is a finite number. The function returns true if the value is a number and is not equal to positive or negative infinity, and false otherwise. In the example, _.isFinite(42) returns true, _.isFinite(-Infinity) returns false, and _.isFinite('42') returns false.
