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 →

Transition control flow methods: end, on, each, call, empty, nodes, node, size

Transition objects have control flow methods: transition.end() is a promise that resolves when transition ends. transition.on(typenames, listener) awaits the end of a transition or listens for transition events. transition.each(function) calls a function for each element. transition.call(function, args) calls a function with this transition. transition.empty() returns true if transition is empty. transition.nodes() returns an array of all selected elements. transition.node() returns the first non-null element. transition.size() returns the count of elements.
