In this video, you will learn how to manipulate the MSG JavaScript object using Change and Function nodes in Node-RED.
The video starts with a brief introduction to the Change node. You will learn how to add a Change node to your flow and modify the MSG object's payload using the Change node. The video then demonstrates the Function node, a powerful node that allows you to write JavaScript code to manipulate the MSG object. You will see examples of writing code in the Function node to replace text in the payload and count the number of words in the message. Overall, this video provides a good introduction to manipulating MSG objects in Node-RED using Change and Function nodes.
