Print numbers inside react component with map?

This is probably an easy one, but I cant seem to figure it out. How do I print the numbers in order inside my list? If i print index some of the numbers will be skipped due to my conditions? Can i set an count++ somewhere inside my map-function inside my condition so it will increase every time a list-item is printed?

export const MFAPaging = ({rootStore, page}) => {
  let count = 1;

  return (
    <div className="components-paging-brder">
      <div className="components-paging">
        <ul>
          {rootStore.mfaStore.links.map((item, index) =>
              item && item.includePage ? 
              <li className={page == index ? 'active' : ''} key={index}>{count}</li>
              : undefined 
            )}
        </ul>
        <MFAButtons rootStore={rootStore} page={page} />
    </div>
  </div>
  );
};
