The function reference will be held in memory, this can lead to performance boost, because it eliminates the need to create a new function on every re-render instead of simply re-using the one allocated function. Creating a function once and then re-use the function instead of potentially creating hundreds of new functions.
This applies when you pass functions as props. You should be fine using map in your render.
