Discussion on: Fast & easy... React states management in one function

[Emmanuel]

In the valueChange function where did you find the state variable. May be it should be obj variable ?

[Fabio Russo]

In the second example?

The state is the obj variable.
You can see I’m creating an obj and using key-value pairs in It.
Then I’m passing the object to setState().

[K]

you defining obj, but then you use state. in non-strict mode this leads to the creation of a global variable, in strict mode this leads to an error.

After that you use obj again, so the new value saved in state in state isn't even used.

Understood!
