How to run JavaScript as soon as we can, but not sooner
You can do so by adding an event listener to the document
object for the DOMContentLoaded
event:
document.addEventListener('DOMContentLoaded', (event) => {
//the event occurred
})
I usually don’t use arrow functions inside for the event callback, because we cannot access this
.
In this case we don’t need so, because this
is always document
. In any other event listener I would just use a regular function:
document.addEventListener('DOMContentLoaded', function(event) {
//the event occurred
})
for example if I’m adding the event listener inside a loop and I don’t really know what this
will be when the event is triggered.
