javascript - Uncaught (in promise) ReferenceError: renge is not defined

Question

我在svelte脚本内部的这个功能中遇到了困难：

  const getRange = function (typ) {
    let range = 0;
    if (typ == 0) {
      range = "A-B";
    } else if (typ == 1) {
      range = "B-c";
    } else if (typ == 2) {
      renge = "C-D";
    } else {
      range = "C-D";
    }
    return range;
  };

模板如下：

    {#each itmes as itme}
               <strong> {getRange(item.typ)}</strong>
              <br />   
    {/each}

但是我在浏览器中得到了他的错误：

Projects.svelte:26 Uncaught (in promise) ReferenceError: renge is not defined
    at Array.getRange (Projects.svelte:26)
    at create_each_block (Projects.svelte:161)
    at Object.update [as p] (Projects.svelte:156)
    at update (index.mjs:1057)
    at flush (index.mjs:1025)

我想知道这里有什么问题，我该如何解决？

range您在else if (typ == 2)子句中拼错了一次：

const getRange = function (typ) {
    let range = 0;
    if (typ == 0) {
      range = "A-B";
    } else if (typ == 1) {
      range = "B-c";
    } else if (typ == 2) {
      range = "C-D";
    } else {
      range = "C-D";
    }
    return range;
  };
