Please take a look Horng.

My apologies for all the white space changes - it is the default react formatter for IntelliJ.

Jason, ran you program and it works. Great Job.
I did misread your code before. Where
addClickHistory = (state, name) => state.clickHistory.concat({ dateTime: new Date().toLocaleTimeString('en-US', options), name: name });
thought you were accessing counter reducer based on the state parameter.
My suggestion is to just pass clickHistory as param to addClickHistory
addClickHistory = (clickHistory, name) => [...clickHistory, { dateTime: new Date().toLocaleTimeString('en-US', options), name: name }];

Updated PR with your suggestions - cleans it up nicely - why pass around the entire stage object when all we care about is click history - got it.
