V té tabulce by se nám v každém měsíci líbila i vypočtená výkonnost podle TWR (time weighted return) principu, ať se to dá srovnávat s jinými, třeba burzovními, investicemi.

  this.handleUploadedRawFile(rawfile, filename)} />

• https://github.com/WojtylaCZ/p2folio/blob/master/src/components/PlatformListView.tsx#L13 mam pocit, ze index z pole jako key neni dobra praxe - lepsi je pouzit neco unikatniho z platformy, nejlepe nejake id nebo pripadne nazev.. kdyz pouzijes index, tak by se to mohlo v nekterych pripadech rozbijet.. napr. kdyz odeberes neco z prostredka pole

  We don’t recommend using indexes for keys if the order of items may change. This can negatively impact performance and may cause issues with component state. Check out Robin Pokorny’s article for an in-depth explanation on the negative impacts of using an index as a key. If you choose not to assign an explicit key to list items then React will default to using indexes as keys.

(je potreba si udelat research jakou zvolit, maji svoje vyhody a nevyhody)

Jinak super! uz je z tebe frontendak :)
