Splice the Mice explainer

Puzzle Explainer
#1

Aim of the puzzle: Use the .splice() array method to replace an element in an array with a new element.
Walk through of solution: .splice() is one of the more flexible array methods, as it can be used to add or remove elements to an array. It takes 3 arguments:

  1. The index to start selecting
  2. The number of items to replace. If 0, splice will not replace any items
  3. The new item(s) to insert

For example, in the following code:

['cheese', 'tomato', 'bread'].splice(1, 1, 'eggs');
// This will replace 'tomato' with 'eggs'

This will start at index 1, remove 1 element, and add the string 'eggs' to the array.

To complete the puzzle, use .splice() on the mice array to replace 1 or more of the elements with a new string.
Sample code solution:

import { mice } from 'grasshopper.mousePad';

mice.splice(1, 1, 'Jerry');

for (let mouse of mice) {
    console.log(mouse);
}
