我有以下數(shù)組要排序。const input = ["12 - Blue, Red, Orange, Purple", "16 - White, Black, Yellow, Blue, Pink","14 -  Yellow, Brown, Grey, Maroon, Green","20 - Red, Black, Yellow, Peach, Aqua","7 - White, Cream, Grey, Green, Magenta" ]目的是按升序?qū)π羞M(jìn)行排序，例如第 7 行，然后是第 12、14、16，最后是第 20。這是我試過但沒有用的const input = [  "12 - Blue, Red, Orange, Purple",  "16 - White, Black, Yellow, Blue, Pink",  "14 -  Yellow, Brown, Grey, Maroon, Green",  "20 - Red, Black, Yellow, Peach, Aqua",  "7 - White, Cream, Grey, Green, Magenta"]var x = input.sort(function(a, b) {  return a[0] > b[0] ? 1 : -1;});console.log(x)如何對(duì)這樣一個(gè)復(fù)雜的數(shù)組進(jìn)行升序排序？
