artydevIn my precedent post I presented an example which was not optimal.
A nice suggestion from Eckehard leaded me to the new version, which is more better as it does not create 'hidden global variables' when using "id's"...
The idea is to not use any external libraries.
function Counter () {
let count = 0
let eltCreate = (tag) => document.createElement(tag)
function View () {
let alltags = ["div", "h3", "button", "button"]
let [div, h3, btninc, btndec] = allElts = alltags.map(eltCreate)
let incby = (incer) => () => h3.innerText = +h3.innerText + incer
allElts.slice(1).forEach(child => div.append(child))
h3.innerText = count
btninc.innerText = "INC"; btninc.onclick = incby(1)
btndec.innerText = "DEC"; btndec.onclick = incby(-1)
return div
}
return View ()
}
[...Array(5)].forEach(() => document.body.append(Counter()))
