 ## Use Cases
 
-You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the **createWebSocket** API to create a **WebSocket** object and then use the **connect** API to connect to the server. If the connection is successful, the client will receive a callback of the **open** event. Then, the client can communicate with the server using the **send** API. When the server sends a message to the client, the client will receive a callback of the **message** event. If the client no longer needs this connection, it can call the **close** API to disconnect from the server. Then, the client will receive a callback of the **close** event.
+You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the **createWebSocket()** API to create a **WebSocket** object and then use the **connect()** API to connect to the server. If the connection is successful, the client will receive a callback of the **open** event. Then, the client can communicate with the server using the **send()** API. When the server sends a message to the client, the client will receive a callback of the **message** event. If the client no longer needs this connection, it can call the **close()** API to disconnect from the server. Then, the client will receive a callback of the **close** event.
 
 If an error occurs in any of the preceding processes, the client will receive a callback of the **error** event.
