onInput Event
Coding HTML forms has been painful my entire career. Form controls look different between operating systems and browsers, coding client side and server side validation is a nightmare, and inevitably you forget something somewhere along the line. Some behaviors don't act the way you'd hope, like onChange, which only fires when the user leaves (blurs) a given form controls. Enter the onInputevent, which changes upon keystroke, paste, etc.
// Try it here: https://codepen.io/darkwing/pen/KKmBNvg
myInput.addEventListener('input', e => {
console.log(e.target.value);
});
These days it seems like the old onChange behavior isn't useful -- we always want to react to any user input. onInput also fires on elements with contenteditable and designmode attributes. Most modern JavaScript libraries like React treat onChange like onInput, so it's as though onChange has lost its use!

![jQuery Chosen Plugin]()
Without a doubt, my least favorite form element is the SELECT element. The element is almost unstylable, looks different across platforms, has had inconsistent value access, and disaster that is the result of multiple=true is, well, a disaster. Needless to say, whenever a developer goes...

CodePen is a treasure trove of incredible demos harnessing the power of client side languages. The client side is always limited by what browsers provide us but the creativity and cleverness of developers always pushes the boundaries of what we think the front end can do. Thanks to CSS...
I agree that onInput is very handy, but I beg to differ on the point that there is no more use for onChange. E.g. in this tutorial for creating a custom audio player: https://css-tricks.com/lets-create-a-custom-audio-player/#play-pause There, the onChange event is used for a range input element to seek to a passage in an audio file. While playing the audio, you might not want the current position in the audio to change on every input, but only after having finished seeking the correct passage.
