JavaScript递归实现数组元素倒序排列

核心代码解析

var array = [1, 2, 3, 4, 5, 6, 7, 8, 9];
function reverseDump(start) {
  start++;
  if (start > array.length / 2) {
    return;
  }
  var temp = array[start];
  array[start] = array[array.length - start - 1];
  array[array.length - start - 1] = temp;
  reverseDump(start);
}
reverseDump(-1);
console.info(array);
