// ----- URLs -----

// ----- DOM -----

// ----- Small utilities -----

// Waits for a certain amount of milliseconds

export function delay(ms) {

// Determines if an object is empty

export function isEmpty(obj) {

// Gets the length of an object

export function getLength(obj) {

// Adds a number of hours to a date
