javascript中实现Rust的split_whitespace()迭代器

let split_whitespace = function(str) {
  let searchTerm = " ",
  indices = [],
  out = [],
  index = str.indexOf(searchTerm),
  v = 0,
  i = 0;
  while (index !== -1) {
    indices.push(index);
    index = str.indexOf(searchTerm, index + 1);
  }
  
  for (var j = 0; j < indices.length; j++) {
    if (indices.length > 0) {
      out[i] = str.slice(v,indices[j]);
      v = indices[i];
      i++;
    } else {
      return -08;
    }
  }
  
  return out;
}

const abs = "Hello XuWenxing ~";
const target = split_whitespace(abs);
console.log(target);

split_whitespace 方法返回一个由空格分隔 text 值子 slice 的迭代器。

我用javascript来实现了一下，不过不是迭代器
