Javascript 字符串数组排序（基于值顺序）

Question

I am currently using a typewriter effect from Codepen and would like to order strings in the order in which they are listed (not random).

function getRandomPun() {
  const puns = [
    "String one",
    "String two",
    "String three"
  ];
  const index = Math.floor(Math.random() * puns.length);

  return puns[index];
}

startType(getRandomPun(), 0);

I have tried replacing the index with Math.floor(Math.round(puns.length) but it has no effect.

function getThePun() {
  const puns = [
    "String one",
    "String two",
    "String three"
  ];
  const index = Math.floor(Math.round(puns.length);

  return puns[index];
}

startType(getThePun(), 0);

I also tried the following but only the first string it outputted:

function getThePun() {
  const puns = [
    "String one",
    "String two",
    "String three"
  ];
  return puns[0];
}

startType(getThePun(), 0);

Any help or tips would be greatly appreciated.

Not sure what the usecase is here, but here is how to sort

 const puns = [ "String shortest", "String - the longest", "String three long" ]; function getRandomPun(len) { if (len) puns.sort((a,b) => a.length - b.length) console.log(puns) const index = Math.floor(Math.random() * puns.length); return puns[index]; } console.log(getRandomPun()); console.log(getRandomPun(true));
