  can i get an index in a map?

  May 08, 2020 11:40 PM|EnenDaveyBoy|LINK

  hi

  I have a functional component which use react-lodash Map to iteerate through an object which is a list of objects, but i would like an index in it and I am going round in circles

  return (
     <nav>
         <ul>              
              <IsEmpty
                  value={data}
                  yes="Empty list"
                  no={() => (             
                      <Map collection={data} iteratee={(obj, key) => 
                          <li>{index}</li>
                          } 
                      />
                   )}
              />       
          </ul>
      </nav>
      )

  i know i could use my keys but my keys are descriptive and i would prefer my index to be numeric, any thoughts would be appiciated

  just convert the mapped object to an array

  <Map collection={Object.entries(data)} iteratee={(entity, index) => 
       <li>{index} - {entity.key} - {entity.value}</li>
     } 
  />
