javascript - 将多个数组插入有序的对象数组中

Question

我有这三个数组:

const time = ["8n", "8n", "4n", "4n", "8n", "8n"];    
const note = [422, 303, 482, 419, 478, 467, 317, 343];    
const velocity = [0.57, 0.28, 0.35, 0.45, 0, 0.4, 0.53, 0.46, 0.48, 0.39];

如何将它们变成这样，注意匹配的索引:

const part = [
  { time: "8n", note: 422, velocity: 0.57 },
  { time: "8n", note: 303, velocity: 0.28 },
  { time: "4n", note: 482, velocity: 0.35 }
];

时间、音符和速度的开始数组长度总是不同的，因此部分长度应该与开始三个中的最小者匹配。

如有任何建议，我们将不胜感激，谢谢。

你是这个意思吗？

const time = ["8n", "8n", "4n", "4n", "8n", "8n"];
const note = [422, 303, 482, 419, 478, 467, 317, 343];
const velocity = [0.57, 0.28, 0.35, 0.45, 0, 0.4, 0.53, 0.46, 0.48, 0.39];

const merge = (timeArr, noteArr, velocityArr) => {
    const length = Math.min(time.length, note.length, velocity.length);
    const ret = [];

    for (let i = 0; i < length; i++) {
        ret.push({
            time: timeArr[i],
            note: noteArr[i],
            velocity: velocityArr[i]
        });
    }

    return ret;
};

console.log(merge(time, note, velocity));
