new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

JSHandle class overview

JSHandle represents an in-page JavaScript object. JSHandles can be created with the page.evaluateHandle method. JSHandle prevents the referenced JavaScript object being garbage collected unless the handle is disposed. JSHandles are auto-disposed when their origin frame gets navigated or the parent context gets destroyed. JSHandle instances can be used as an argument in page.evalOnSelector, page.evaluate, and page.evaluateHandle methods.
