The ternary operator ? is a way of shortening an if-else clause, and is also called an immediate-if statement in other languages (IIf(condition,true-clause,false-clause) in VB, for example).
The conditional (ternary) operator is the only JavaScript operator that takes three operands. This operator is frequently used as a shortcut for the if statement.
The ternary operator can be used to combine two expressions but an empty statement is not an expression. A method invocation can be used as an expression if the method returns a value (read: is not declared void) and it could be used together with a dummy constant null to form a ternary operator but the result would be again an expression which is not allowed in places where a statement is ...
"The ternary expression is a statement", the ternary expression is a expression, it expresses a value, if/else is a statement, ternary could become an expression statement but I would say by itself it is an expression, this is what makes turnery pretty powerful in my opinion.
The ternary operator can be used in places where the if..else construct can't, for example in return statements, and as function arguments. The same could be achieved without ternary use, but results in longer code and larger executables.
Which ternary operator are you talking about? A ternary operator is any operator that takes three arguments. If you're talking about the ? : operator, this is called the conditional operator. I can't live without it anymore, personally. If - else statements look so messy to me, especially when doing a conditional assignment. Some complain that it looks messy, but it is still possible ...
An if / else statement emphasises the branching first and what's to be done is secondary, while a ternary operator emphasises what's to be done over the selection of the values to do it with. In different situations, either may better reflect the programmer's "natural" perspective on the code and make it easier to understand, verify and maintain.
The ternary operator is a syntactic and readability convenience, not a performance shortcut. People are split on the merits of it for conditionals of varying complexity, but for short conditions, it can be useful to have a one-line expression. Moreover, since it's an expression, as Charlie Martin wrote, that means it can appear on the right-hand side of a statement in C. This is valuable for ...
From what I know, PowerShell doesn't seem to have a built-in expression for the so-called ternary operator. For example, in the C language, which supports the ternary operator, I could write somet...
The ternary operator is a concise way to write simple conditional expressions in a single line. It can be particularly useful when assigning values or constructing expressions based on conditions.
