题解 | #字符串最后一个单词的长度#

const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void (async function () {
    while ((line = await readline())) {
        console.log(line.trim().split(" ").pop().length)
    }
})();

通过字符串分割，字符串pop方法返回的最后一个元素，获取长度
