Examples for a blog post on rewriting jQuery's .each() in Vanilla JS

sample.js

// Select all HTML elements with class .text-input
var $inputs = $('.text-input');

// Create event handling functions
function textInputFocusHandler(){ console.log('focus');}
function textInputBlurHandler(){ console.log('blur'); }

// Attach focus & blur handlers to selected inputs
$inputs.on('focus', textInputFocusHandler);
$inputs.on('blur', textInputBlurHandler);
