• Switch statements: do you need the last break? (Javascript mainly)

  - by Jon Raasch

  When using a switch() statement, you add break; in between separate case: declarations. But what about the last one? Normally I just leave it off, but I'm wondering if this has some performance implication I'm not thinking about? I've been wondering about this for a while and don't see it asked elsewhere on Stack-O, but sorry if I missed it. I'm mainly asking this question regarding Javascript, although I'm guessing the answer will apply to all switch() statements.

  - by Joo Park

  I'm wondering how one would translate a sql string to an expression tree. Currently, in Linq to SQL, the expression tree is translated to a sql statement. How does on go the other way? How would you translate select * from books where bookname like '%The%' and year > 2008 into an expression tree in c#?

• Is using the break statement bad practice?

  - by Lchi

  I've been told by professors and peers at my university that using the break statement is bad practice, but through my coursework haven't come up with a great reason why. Those who claim that it is bad say that it's a "get out of jail free card" and that you can always avoid using it. My guesses for why its considered bad would be that you could possibly skip some cleanup code after the break, or similarly exit some control structure in an inconsistent state. Is there any reason why using break is(n't) bad practice?

• Should a function have only one return statement?

  - by David

  Are there good reasons why it's a better practice to have only one return statement in a function? Or is it okay to return from a function as soon as it is logically correct to do so, meaning there may be many return statements in the function?

• Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID

  - by Jian Lin

  Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID); ? The ( ) usually is for specifying grouping of something. But in this case, are we supposed to be able to use 2 or more field names... in the example above, it can be all clear that it is 1 field, is it just that the parser is not made to bypass the ( ) when it is all clear? (such as in the language Ruby).

• Ternary operator in if-statement?

  I've written the following if-statement in Java: if(methodName.equals("set" + this.name) || isBoolean() ? methodName.equals("is" + this.name) : methodName.equals("get" + this.name)) { ... } Is this a good practice to write such expressions in if, to separate state from condition? And can this expression be simplified?

• why is optional chaining required in an if let statement

  - by b-ryan ca

  Why would the Swift compiler expect me to write if let addressNumber = paul.residence?.address?.buildingNumber?.toInt() { } instead of just writing: if let addressNumber = paul.residence.address.buildingNumber.toInt() { } The compiler clearly has the static type information to handle the conditional statement for the first dereference of the optional value and each following value. Why would it not continue to do so for the following statements?

• Nested if statements or not

  - by Zaps

  Hi, I hope this hasn't been asked before. I have a nullable boolean called boolIsAllowed and a if condition like so: if(boolIsAllowed.HasValue && boolIsAllowed.Value) { //do something } My question is this good code or would I be better separating it into a nested if statement? Will the second condition get checked if boolIsAllowed.HasValue is equal to false and then throw an exception? I hope this question is too stupid. Thanks in advance.
