If-Else conditional logic operator ? : in Bicep

Bicep includes a decision-making operator combination isTrue ? thenValue : elseValue which is called the conditional operator or ternary operator. It is the short form of the if-else conditions.

Syntax

param initValue bool = true

output outValue string = initValue ? 'true value' : 'false value'

Nested Ternary Operator and meaning of life

Nested ternary operators are possible by including a conditional expression as a second statement.

param x int = 1
param y int = 2

var result = x > y ? 'x is greater than y' : x < y ? 'x is less than y' : x == y ? 'x is equal to y' : '42';

output result string = result

Above snippet would output ‘x is less than y’.
