javascript - 根据另一个数组的奇数和偶数索引元素创建数组

我想用sentences数组的奇数和偶数索引填充两个数组(links和sentence):

这是我尝试未成功的尝试:

     let link_sentence = ">60-1> don't you worry >6-2> I gonna make sure that >16-32> tomorrow is another great day"; //

        let sentence =  link_sentence.split(">")
        let sentences= []
        let links = []
        for(let i = 0; i < sentence.length; i += 2) {

            sentences.push(sentence[i]);
        }
        console.log(sentences)

预期输出应为:

//let links = ["60-1", "6-2", "16-32"];
//let sentences = ["don't you worry", "I gonna make sure that", "tommorow is  another great day"];

最佳答案

您可以匹配部分，并省略分割的空字符串。

var link_sentence = ">60-1> don't you worry >6-2> I gonna make sure that >16-32> tomorrow is another great day",
    sentences = [],
    links = [];

link_sentence
    .match(/\>[^>]+/g)
    .reduce(
        (r, s, i) => (r[i % 2].push(s.slice(1)), r),
        [links, sentences]
    );

console.log(sentences);
console.log(links);
