javascript - 格式化数组以在 node.js 中输出

Question

var toFormat = [[1, "one", "unu"], [2, "two", "du"], [3, "three", "tri"], [4, "four", "kvar"]];

我需要输出数组 toFormat 所以它应该是这样的:

1 (one)
2 (two)
3 (three)
4 (four)

(每个子数组的第三个元素不用)如何做到这一点？

编辑:循环在这里

var res = []; 
for(var i=0;i<toFormat.length;i++){
    res.push(toFormat[i][1]+" ("+toFormat[i][2]+")");
}
console.log(res.join("\n"))

Answer 1

const toFormat = [
   [1, "one",   "unu"], 
   [2, "two",   "du"], 
   [3, "three", "tri"], 
   [4, "four",  "kvar"]];

const result = toFormat.map(([val, string]) => `${val} (${string})`).join('\n');

console.log(result);
