Then import the each function and use it on an array:

index.ts
import { each } from 'underscore';

const array = [1, 2, 3];

each(array, (value: number, index: number) => {
  console.log(`Value at index ${index} is ${value}`);
});

The each function takes two arguments: an array to iterate over and a function to invoke for each element in the array. The function receives two arguments - the current value and index of the element being iterated over.

Note the use of type annotations to ensure that the value and index arguments are of the correct type.
