This code is part of the counter example project. It is an impoved version of the Vanilla JavaScript counter I posted a while ago. This version was posted by Jon Randy as a reply to my post.
<form>
<input id="counter" type="button" value="0">
<input type="reset">
</form>
<script>
const form = document.forms[0]
const increment = () => console.log(++form.counter.value)
const reset = () => form.counter.value = 0
form.addEventListener('reset', reset)
form.counter.addEventListener('click', increment)
</script>
A few notes as I am trying to understand this example:
- The
value
attribute of aninput
element oftype="button"
is the value shown by the browser on the button. - I am still not used to the fat-arrow notation of creating anonymous functions in JavaScript that are then assigned to a variable.
() => code
is a function definition.
It is indeed a very nice use of the various default capabilities of HTML and JavaScript.
