I know how to select the nth element of a certain type document.querySelectorAll('.myClass')[n],

but given an element myEl = document.querySelector('.myClass .myOtherClass'),

how do I then determine its place (its "n") in the array of elements selected by document.querySelectorAll('.myClass')?

do this:

document.querySelectorAll(".myClass").indexOf(yourElement) // ==> your index

U can try something like that:

Array.prototype.indexOf.call(document.querySelectorAll('.myclass'),myEl)
