Ternary Conditional operator
on Saturday, 18th of July, 2020
The ternary operator is technically that: an operator. But, it's also kind of an
else substitute. It's also kind of a
?? alternative, depending on the situation. The ternary expression is used to conditionally assign a value. It's called ternary because it has three portions: the condition, the value if the condition is true, and the value if the condition is false.
String alert = isReturningCustomer ? 'Welcome back to our site!' : 'Welcome, please sign up.';
In the above example
isReturningCustomer is a boolean. If it is true, the variable called
alert will be assigned the value "Welcome back to our site!". Otherwise,
alert will be assigned the value "Welcome, please sign up.".
