[removed] Object Rename Key

Question

Is there a clever (i.e. optimized) way to rename a key in a javascript object?

A non-optimized way would be:

o[ new_key ] = o[ old_key ];
delete o[ o         


        

Answer 1

If you don’t want to mutate your data, consider this function...

renameProp = (oldProp, newProp, {[oldProp]:old, ...others}) => ({
    [newProp]: old,
    ...others
})
