JavaScript ternary without else

The conditional (ternary) operator is the only JavaScript operator that takes three operands: a condition followed by a question mark ( ? ), then an expression to execute if the condition is truthy followed by a colon ( : ), and finally the expression to execute if the condition is falsy.

Ternary Operator in Swift A ternary operator evaluates a condition and executes a block of code based on the condition . Its syntax is condition ? expression1 : expression2. Here, the ternary operator evaluates condition and. if condition is true, expression1 is executed.

Swift has a rarely used operator called the ternary operator . It works with three values at once, which is where its name comes from: it checks a condition specified in the first value, and if it’s true returns the second value, but if it’s false returns the third value.

It helps to think of the ternary operator as a shorthand way or writing an if-else statement . Here’s a simple decision-making example using if and else: int a = 10, b = 20, c; if (a < b) { c = a; } else { c = b; } printf(“%d”, c); This example takes more than 10 lines, but that isn’t necessary.
