Stimulus slideshow controller, because I'm too stupid to do modulo math

slideshow_controller.js

import { Controller } from "@hotwired/stimulus"

export default class extends Controller {
  static targets = [ "slide" ]

  initialize() {
    this.index = 1
  }

  next(e) {
    e.preventDefault()
    this.slideTargets.forEach(c => { c.classList.add('hidden') })
    this.slideTargets[(this.index++%this.slideTargets.length)].classList.remove('hidden')
  }
}
