Rozšiřitelnost není znásilňování.knihovna od zakladu prekopavajici cely jazyk za ucelem, aby se dal ten jazyk pouzivat k tomu, k cemu byl vubec navrzeny mi prijde opravdu trochu jako zvracenost a znasilneni
Jo, a největší prča na tom je, že ta knihovna nemění vůbec nic.to jo. mimochodem, osobne radsi preferuju dojo, prijde mi takove nejake civilizovanejsi.
Čekal bych, že zrovna ty budeš mít trochu pochopení, v JavaScriptu je pod pár vrstvami špíny a hnusu ukryté Scheme, které by mohly pochopit i masyano, jedna cast meho ja ocenuje, ze tam je opravdu schovany scheme, a ze JS zpristupnuje funkcionalni zpusob programovani i sirokym masam. ale ta druha cast meho ja, ktera v tom obcas musi neco programovat by autory specifikace i s implementatory vymachala v dehtu a peri a hnala je pres cele silicon valley.
