Window控制:Window对象提供了移动(moveTo、moveBy)、改变大小(resizeTo、resizeBy)、滚动窗口(scrollTo、ScrollBy)、得到焦点(focus)、放弃焦点(blur)的方法。更重要的一个方法是open,它可以打开一个新的窗口,例:var w = open("url.html", "window name", "re
Use Object.entries() to loop over array objects and compare them in pairs. Return 0 if the direction changes or the direction if the last element is reached. const isSorted = arr => { let direction = -(arr[0] - arr[1]); for (let [i, val] of arr.entries()) { direction = !
