How to use the change-case.capitalCase function in change-case

.map( ( cardinalDirection ) => {
                      const count = listingCounts.location.cardinalDirection[cardinalDirection];
                      return (
                        { `${capitalCase( cardinalDirection )} of Boston (${count || '0'})` }
                      );
                    } )
                }

.map((serviceId) => {
          const name = capitalCase(serviceId)
          const slug = getServiceSlug(serviceId)
          const operations = operationObjects.filter(
            (o) => getServiceId(o.operationId) === serviceId
          )
          return { name, slug, operations }
        })[0]

const getNextStepName = () => {
    const nextStep = ( step + 1 );
    const stepDefinition = props.steps[nextStep - 1];

    if ( stepDefinition ) {
      return capitalCase( stepDefinition.component.displayName );
    }

    return null;
  };

function getServiceSlug(serviceId) {
  return slugify(capitalCase(serviceId))
}

const order = serviceIds.map((serviceId) => {
    return {
      title: capitalCase(serviceId),
      indexData: true,
      path: getServiceSlug(serviceId),
    }
  })
  return order

      return 'Condominium';

    case 'multi-family':

    default:
      return capitalCase( type );
  }
}

                      const count = listingCounts.location.neighborhood[neighborhood];
                      return (
