Building Web Applications with Angular

På denna kurs lär du dig att bygga responsiva och företagsanpassade applikationer som körs smidigt på både stationära som mobila enheter. Ramverket Angular erbjuder ett robust system som underlättar utvecklingen av mycket interaktiva applikationer, som kan köras på flera plattformar. Samla på dig erfarenhet genom att bygga komponenter, skapa direktiv element, forma applikationer och bygga mallbaserade former.
