javascript - 如何在javascript中使用递归打印数组中的元素

Question

Array.prototype.myForEach = function(element) {
  for (var i = 0; i < this.length; i++) {
    element(this[i], i, this);
  }
};

var forArr = ['8', '17', '25', '42','67'];
forArr.myForEach(function(exm){
  console.log(exm);
});

我在表格里写了。你能帮忙把它翻译成递归吗？

Answer 1

var forArr = ['8', '17', '25', '42','67'];

var recursive_function = function(array){
  if(array.length > 0){
    console.log(array[0]);
    recursive_function(array.slice(1))
  }
}

recursive_function(forArr)
