When I set counterN = {counter} in order to enscapsulate (inside counters.jsx)  
and then set this.props.counterN.value and this.props.counterN.id (inside counter.jsx)  
I get the error  
"index.js:1 Warning: Received NaN for the `children` attribute.  
If this is expected, cast the value to a string. "

Can you please JUST confirm if it’s just me  
or the code Mosh teach us is now obsolete? - I use the newest React -  
Thanks in advance

[SOLVED] The problem was that I had set counterN={counter}  
this.props.counterN.value and this.props.counterN.id (inside counter.jsx)

supposing that counterN in counterN = {counter} was a variable
