VSCode config to disable popular extensions' annoyances (telemetry, notifications, welcome pages, etc.)
// I'm tired of extensions that automatically:
// - show welcome pages / walkthroughs
// - show release notes
// - send telemetry
// - recommend things
//
// This disables all of that stuff.
// If you have more config, leave a comment so I can add it!!

Simple library with lazy es6 iterables. If you use es5 - don't forget to add es5 polyfill

yield start

let tmp = start;
if (start < finish) {
while (tmp < finish) {
