Yes, it is a shorthand form of int count; if (isHere) count = getHereCount(index); else count = getAwayCount(index); It’s called the conditional operator. Many people (erroneously) call it the ternary operator, because it’s the only ternary (three-argument) operator in Java, C, C++, and probably many other languages. But theoretically there could be another ternary operator, … Read more
Angular 1.1.5 added support for ternary operators: {{myVar === “two” ? “it’s true” : “it’s false”}}
Update: Angular 1.1.5 added a ternary operator, so now we can simply write <li ng-class=”$first ? ‘firstRow’ : ‘nonFirstRow'”> If you are using an earlier version of Angular, your two choices are: (condition && result_if_true || !condition && result_if_false) {true: ‘result_if_true’, false: ‘result_if_false’}[condition] item 2. above creates an object with two properties. The array syntax … Read more
Use the ternary operator: name = ((city.getName() == null) ? “N/A” : city.getName()); I think you have the conditions backwards – if it’s null, you want the value to be “N/A”. What if city is null? Your code *hits the bed in that case. I’d add another check: name = ((city == null) || (city.getName() … Read more
What you have is a fairly unusual use of the ternary operator. Usually it is used as an expression, not a statement, inside of some other operation, e.g.: var y = (x == 2 ? “yes” : “no”); So, for readability (because what you are doing is unusual), and because it avoids the “else” that … Read more
$result = If ($condition) {“true”} Else {“false”} For use in or as an expression, not just an assignment, wrap it in $(), thus: write-host $(If ($condition) {“true”} Else {“false”})
It is the ternary operator, and it works like in C (the parenthesis are not required). It’s an expression that works like: if_this_is_a_true_value ? then_the_result_is_this : else_it_is_this However, in Ruby, if is also an expression so: if a then b else c end === a ? b : c, except for precedence issues. Both are … Read more
Since everything is an expression, and thus results in a value, you can just use if/else. a = if true then 5 else 10 a = if false then 5 else 10 You can see more about expression examples here.
You don’t necessarily need jQuery. JavaScript alone will do this. var a = 2; var b = 3; var c = ((a < b) ? ‘minor’ : ‘major’); The c variable will be minor if the value is true, and major if the value is false. This is known as a Conditional (ternary) Operator. https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/Conditional_Operator
As pointed out (and hopefully unsurprisingly), using if+else is indeed the idiomatic way to do conditionals in Go. In addition to the full blown var+if+else block of code, though, this spelling is also used often: index := val if val <= 0 { index = -val } and if you have a block of code … Read more
