一次遍历 Javascript 数组多个元素的惯用方法是什么?

What is the idiomatic way to loop over a Javascript array multiple elements at a time?

在Python中,您可以进行以下操作:

>>> foo = ["some", "random", "list", "foo"]
>>> for a, b, c in zip(foo, foo[1:], foo[2:]):
...     print(f"{a} {b} {c}")
... 
some random list
random list foo

如何在 Javascript 中做同样的事情而不用在循环中使用位置索引?或者这是惯用的方式?

你可以拿一台发电机去拿零件。

function* zip(array, n) {
    let i = 0;
    while (i + n <= array.length) {
        yield array.slice(i, i + n);
        i++;
    }
}

let foo = ["some", "random", "list", "foo"];

for (let [a, b, c] of zip(foo, 3))
    console.log(a, b, c);
