What does the error say in the console?

Question

JavaScript

React application gives such a message to the console, I don’t even know where to dig.

Let me know if anyone has come across

Answer 1

In the render method, you access the id property of a non-existent object. The error is eliminated in the following ways:
1. Set the initial state / props.
2. Check for the existence of an object before accessing its property.

Answer 2

ncaught TypeError: Cannot read property 'id' of undefined

can't read id of "nothing"
