## you presumably already know that this returns false, because of the way floats are stored:
0.1 + 0.2 == 0.3
# => false


# we can create a more useful way of comparing floats that matches what humans would expect:
class Float
  def =~(number, tolerance = 0.0001)
    (self - number).abs < tolerance

What is a literal?

In programming languages, literals are textual representations of values in the source code. This is a syntactical concept.

import { Controller } from "@hotwired/stimulus"

export default class extends Controller {
  connect() {
    addEventListener("turbo:submit-end", ({ target }) => {
      clearInterval(this.interval);
      this.element.innerHTML = this.originalLabel;
    })
    this.originalLabel = this.element.innerHTML;
  }

* my laptop (and the server) are managing Ruby with rbenv;
* vim is my remote editor of choice, and an acceptable local editor; and
