QUESTION
I am writing a React app in which somebody can sign up as a business or user, and a user is able to search for a business by name.

2: Please make sure if data exists in your store, you can use redux-dev-tools for that.
3: The first time that your component renders there is no data in your store and it's just an empty array so please first check if name
exists and has value then try to convert it to lower case.
It would be something like this:

it means /

or /register
.Then your logic is confused with this so that other pages are not working. Best way to develop as you expect like first one.

What could be the problem? Below is the little snippet of, first, the Employee class:
...ANSWER
Answered 2020-Jan-15 at 21:16When you call Employee::businessCard();
it will call const char* name() const { return _name.c_str() ; }
