为什么我提示堆栈溢出？
function BinaryTree() {
var Node = function (key) {
this.key = key;
this.left = null;
this.right = null;
};
var root = null;
var insertNode = function (node, newNode) {
if (newNode.key < node.key) {
if (node.left === null) {
node.left = newNode;
} else {
insertNode(node.left, newNode);
}
} else {
if (node.right === null) {
node.right = newNode;
} else {
insertNode(node.right, newNode);
}
}
}
this.insert = function (key) {
var newNode = new Node(key);
if (root === null) {
root = newNode;
}
insertNode(root, newNode);
}
}
var nodes = [8, 3, 10, 1, 6, 14, 4, 7, 13];
var binaryTree = new BinaryTree();
nodes.forEach(function (key) {
binaryTree.insert(key);
//console.log(binaryTree);
})
