The goal of the exercise is to find an efficient way to take an existing word and lookup all words in a dictionary that differ from the original by only a single character. This is the kernel function for larger algorithmic problems like the Word Ladder, where you try to find the shortest route between two words, by changing one character at a time, and where each intermediate step must be in an intial dictionary of words.

The simplest algorithm possible will take the input word and then compare it against every word in the dictionary, character by character, and count the differences. If the character differences between the word are just 1, then we add it to our list, otherwise we reject it. JavaScript has the Array.filter method which does precisely what we want and we just supply a function which returns true or false depending on if our criterion are met.
It is possible to optimize differsByOne further to get more benefits, but given t

At the time of writing, the input devices landscape is fragmented, very fragmented.
Beside a few common concepts inherited from the very first input devices (mouses and keyboards),
it's impossible to get out of input devices the raw input they collect and make something useful out of it.
Inspirations
The aim of this proposal is to philosophically draw from the Pointer Events specification and
unify a large range of input devices by providing a new set of fundamental concepts
