题解 | 单组_A+B javascript node模式

//创建接口, 监听标准输入
const rl = require("readline").createInterface({input: process.stdin});
//获取接口的迭代器
var iter = rl[Symbol.asyncIterator]();
//通过迭代器等待并返回下一行输入内容
const readline = async() => (await iter.next()).value;

void async function() {
    while(line = await readline()) {
        let tokens = line.split(' ');
        let a = parseInt(tokens[0]);
        let b = parseInt(tokens[1]);
        console.log(a + b);
    }
}()
