Vorbereitungen und Werkzeuge
1.1 HTML und CSS
1.1.1 Korrektes HTML
Es ist nicht wichtig, ob Sie bereits PHP, TypeScript oder Java programmiert haben: Ohne solide Kenntnis und Erfahrung mit HTML und CSS ist der Einstieg in JavaScript steil und steinig. Schließlich ist ein Hauptgrund für den Einsatz von JavaScript der Eingriff in die Darstellung der Webseite. Valides – also korrektes – HTML ist die Basis für JavaScript. Obwohl die Browser viele HTML-Fehler ignorieren, schlagen falsch verschachteltes HTML und fehlende Hochkommas im HTML-Tag zurück. Darum gehört der Validator zum Alltag des JavaScript-Programmierers.
