Played a bit of code golf with your snippet, but can't figure out how to combine the .map(Number).filter(Number):
let avgAge = [...document.querySelectorAll('.commtext')]
.map(span => parseInt(span.innerText))
.map(Number)
.filter(Number)
.reduce((i,d,c, ages) => ages.reduce((x, y) => x+y) / ages.length)
