Javascript 我希望这段代码不会太长，也不会太耗时

我希望能够继续开发这段代码，但编写这段代码要花很多时间。有没有办法让它更简单？我的意思是，写起来花更少的时间更容易

这就是所有的代码。

我总能看到我的重复试图达到什么目的

1） 从数组中获取随机字

2） 检查某物是否以元音开头

可以这样表达

const getRandom = (arr) => arr[(Math.floor(Math.random() * arr.length -1) + 0)] //following your code not sure if this is correct random
const startsWithVowel = (str)=>/^[aeiou]/.test(str)

然后你的代码会缩短到这个

var a = ["The","an","a"]
var b = ["deranged","squishy","original","excellent","extraordinary","big nosed","big bird lookin","angry"]
var c = ["cat","shrimp","silas","lobster","isaac","atticus","molly","jorge","POLYNOMIAL"]
var verb = ["flew","jumped","died","boinged"]
var con = ["and","but","or"]
var prep = ["over","on","off","under"]
var op = ["bridge","house","octopus","swing","boat"]
var at = ["The","an","a"]

const getRandom = (arr) => arr[(Math.floor(Math.random() * arr.length -1) + 0)]
const startsWithVowel = (str)=>/^[aeiou]/.test(str)

let tobea = getRandom(a),
    tobeb = getRandom(b),
    tobec = getRandom(c),
    tobed = a[getRandom([0,1])],//get 'The' or 'a'
    tobee = a[getRandom([0,2])],//get 'The' or 'an'
    tobeverb =getRandom(verb),
    tobecon = getRandom(con),
    tobeprep = getRandom(prep),
    tobeop = getRandom(op),
    tobeat = getRandom(at);

    tobeat = startsWithVowel(tobeop) ? tobed : tobee
    tobeb = startsWithVowel(tobeb) ? tobed: tobee

    var output = tobea + " " + tobeb + " " + tobec + " " + tobeverb + " " + getRandom(prep) + " " + tobeat + " " + getRandom(op);


    document.getElementById("jesus").textContent = output;

    document.getElementById("clickMe").onclick = reload;

您可以看到getRandom可以以不同的方式使用，因为它非常通用。重构时，始终尽可能多地编写泛型函数

您可能需要考虑使用一些字符串和/或数组方法，如

indexOf

或

includes

来缩短
