Bedingungsoperatoren in JavaScript sind wesentlich für Entscheidungsfindungen im Code. Sie ermöglichen die Ausführung verschiedener Aktionen basierend auf unterschiedlichen Bedingungen.
Die if
-Anweisung ist der grundlegendste bedingte Operator, der verwendet wird, um einen Block von Code nur auszuführen, wenn eine bestimmte Bedingung wahr ist.
Syntax:
Beispiel:
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה

Die else
-Anweisung ergänzt die if
-Anweisung und ermöglicht die Ausführung von Code, wenn die if
-Bedingung falsch ist.
Syntax:
if (condition) {
} else {
}
Beispiel:
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה

else if
ermöglicht das Testen von mehreren Bedingungen in Folge.
Syntax:
if (condition1) {
} else if (condition2) {
} else {
}
Beispiel:
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה

Der ternäre Operator ist eine Kurzform für die if...else
-Anweisung, nützlich für die Zuweisung von Werten basierend auf einer Bedingung.
Syntax:
let result = (condition) ? value1 : value2;
Beispiel:
let message = (temperature > 30) ? "It's a hot day" : "It's not a hot day";
Die Beherrschung von bedingten Operatoren in JavaScript ist entscheidend für die Erstellung von dynamischem und reaktionsschnellem Code. Diese Operatoren ermöglichen es dem Skript, Entscheidungen zu treffen und unter unterschiedlichen Bedingungen unterschiedlich zu reagieren.
