Answer 1

// We're going to get all the elements and force them into an array,
//  rather than a nodeList. That's what the [... and ] are doing to
//  our selector.
let myElements = [...document.getElementsByClassName('_2hvTZ pexuQ zyHYP')],
    arrayOfIds =  [];

// We can now use each member of myElements in a forEach. Within that,
//  the current member is called 'element'. So we can see its ID, and do
//  whatever we need to do with that.
myElements.forEach(function (element){ arrayOfIds.push(element.id);} );

console.log(arrayOfIds)
