Reactjs: Key undefined when accessed as a prop

Question

Tools: Reactjs 0.14.0 Vanilla Flux

I need unique identifiers for 2 reasons:

1. Child Reconciliation
2. Keeping track of what child

Answer 1

It is best to use id. Then in the eventHandler you can have event.target.id.

function getMessageListItem(message) {

  return (
    
  );
}
