`this.indexOf = function(element) {
var current = head;
var index = -1; //这里应该为0 吧
while (current) {
if (element === current.element) {
return index;
}
index++;
current = current.next;
}
return -1;
};
var list = new LinkedList(); function f(){ console.log('fff') } list.append(f); console.log(list.indexOf(f));
isAmpty 这个是不是isEmpty (拼写错误?)
peek方法是不是要加一下判断(item为长度为0的时候):
this.peek = function() {
if(this.size > 0) {
return items[items.length - 1];
} else {
console.log("the item is empty");
}
}
var removeNode = function(node, key) {
// 如果根节点不存在,则直接返回null
if (node === root) { // line235: should be `node === null`
return null;
}
每个够咱函数里都用this 很耗内存的啦
