## Opgave
Du skal opbygge en detaljeret visning af raceinformation. Efter at have hentet racedata fra API'et, skal du vise hver races navn, beskrivelse, forventede levetid, vægtintervaller for han- og hunhunde samt status for hypoallergene egenskaber.
1. Brug Axios til at hente data fra `https://dogapi.dog/api/v2/breeds`, når knappen "Fetch Breeds" klikkes, og indpak forespørgslen i et try-catch-blok.
2. Hvis der opstår en fejl under API-forespørgslen, skal du skjule indlæsningsindikatoren og vise en fejlmeddelelse.

Behersk væsentlige JavaScript-koncepter, herunder klasser, DOM-manipulation, eventhåndtering og asynkron programmering. Lær at skabe dynamiske og interaktive webapplikationer ved at håndtere brugerinteraktioner, hente og vise data samt håndtere asynkrone operationer effektivt. Gennem en kombination af teori, praktiske udfordringer og virkelighedsnære eksempler giver dette kursus dig de praktiske færdigheder, der er nødvendige for moderne webudvikling.

Lær grundlæggende JavaScript-klasser, fra klassedeklarationer til definition af metoder, der udvider funktionaliteten. Opdag, hvordan parameterobjekter anvendes effektivt, håndtering af private egenskaber og adgangskontrol med getters og setters. Behersk statiske egenskaber og statiske metoder, og udnyt styrken ved klassearv ved brug af "extends" og "super()" til at opbygge skalerbar og genanvendelig kode.

Behersk DOM-manipulation for at skabe dynamiske, interaktive webapplikationer. Naviger og modificer DOM-strukturen, opdater indhold dynamisk, og implementer bedste praksis for sikkerhed og ydeevne. Skeln mellem egenskaber og attributter for at optimere din kode.

Lås op for interaktiviteten i dine webapplikationer ved at mestre JavaScript-hændelser. Forstå hændelsespropagering, kontroller hændelsesadfærd, og implementer effektiv hændelseshåndtering for brugerinteraktioner. Optimer ydeevnen med avancerede teknikker som hændelsesdelegering.

Dyk ned i asynkron JavaScript, herunder callbacks, Promises og async/await. Lær at hente data fra API'er, integrere tredjepartsbiblioteker og håndtere flere forespørgsler effektivt, hvilket opbygger færdigheder til at skabe datadrevne applikationer.
