Verwendung von Import - Module in (ES6)

+

+ Die statische + import-Statement Deklaration wird verwendet, um schreibgeschützte, dynamische Bindings zu importieren, die von + einem anderen Modul exportiert werden. Die importierten Bindings werden dynamische Bindings genannt, weil sie + durch das Modul, das das Binding exportiert, aktualisiert werden, aber nicht durch das importierende Modul neu + zugewiesen werden können. +

+

+ Um die import-Deklaration in einer Quelldatei zu verwenden, muss die Datei zur Laufzeit als Modul + interpretiert werden. In HTML geschieht dies, indem type="module" zum + <script>-Tag hinzugefügt wird. Module werden automatisch im Strict Mode interpretiert. +

+ +

+ Es gibt auch eine funktionsähnliche dynamische import(), die keine Skripte des Typs + type="module" erfordert. +

+
+

Um die Modul-Schreibweise in JS zu verwenden, müssen folgende Punkte berücksichtigt werden:
