Javascript 如何快速确定给定zipcode的状态？

我不需要城市或地址，只需要州。如果可能的话，我不想进行API调用。优先考虑的是一个轻量级的解决方案，理想情况下只是Javascript

我有一个用户输入

zipcode

，我想根据zipcode所处的状态显示一段文本。我知道查找城市和州要复杂得多，因此像USPS公开的API可能是最好的。但是，为了仅仅匹配状态，也许仅仅在前三个数字上，解决方案（我认为）应该是简单和轻量级的

---

Javascript是最理想的。PHP也可以工作。

美国zipcode数据事实上足够稳定，如果只需要州（而不是城市或其他任何地方）的话，您可以在不点击API或数据库的情况下完成这项工作

下面是一个轻量级JS解决方案，它采用zipcode（作为字符串），确定正确的美国州，并将州作为两个字母的邮政缩写返回。如果愿意，还可以通过在最后一行返回

state

而不是

st

来返回州的全名

function getState(zipString) {

  /* Ensure param is a string to prevent unpredictable parsing results */
  if (typeof zipString !== 'string') {
      console.log('Must pass the zipcode as a string.');
      return;
  }

  /* Ensure we have exactly 5 characters to parse */
  if (zipString.length !== 5) {
      console.log('Must pass a 5-digit zipcode.');
      return;
  }

  /* Ensure we don't parse strings starting with 0 as octal values */
  const zipcode = parseInt(zipString, 10);

  let state;
