-## Note
-
-Before `3.4.0`:
-The number of treeNodes can be very large, but when `checkable=true`,
-it will increase the compute time. So, we cache some calculations (e.g. `this.treeNodesStates`)
-to avoid double computing. But, this brings some restrictions.
-**When you load treeNodes asynchronously, you should render tree like this**:
-
-```jsx
-{this.state.treeData.length
-  ? <Tree>{this.state.treeData.map(data => <TreeNode />)}</Tree>
-  : 'loading tree'}
-```

-## 注意
 
-在 `3.4.0` 之前：
-树节点可以有很多，但在设置`checkable`时，将会花费更多的计算时间，因此我们缓存了一些计算结果（`this.treeNodesStates`）来复用，避免多次重复计算，以此提高性能。但这也带来了一些限制，当你异步加载树节点时，你需要这样渲染树：
 
-```jsx
-{this.state.treeData.length
-  ? <Tree>{this.state.treeData.map(data => <TreeNode />)}</Tree>
-  : 'loading tree'}
-```
