Conditional expressions[edit]
| Pattern matching | conditional expression | |

| Java | ||
| JavaScript | ||
| PHP | ||
| C# | ||
| Windows PowerShell | ||
| Perl | condition ? valueIfTrue : valueIfFalse | |
| Ruby | ||
| Common Lisp | (if condition valueIfTrue valueIfFalse) | |
| Scheme | ||
| Pascal | ||
| Visual Basic | IIf(condition, valueIfTrue, valueIfFalse) | |
| Visual Basic .NET | If(condition, valueIfTrue, valueIfFalse) | |
| Python | — | valueIfTrue if condition else valueIfFalse |
| S-Lang | ||
| FORTRAN 77 | ||
| Forth | condition IF valueIfTrue ELSE valueIfFalse THEN | |
| OCaml | match value with
| pattern2 -> expression ... «| _ -> expression»[a] |
if condition then valueIfTrue else valueIfFalse |
| F# | ||
| Standard ML | case value of
| pattern2 => expression ... «| _ => expression»[a] | |
| Haskell (GHC) | case value of {
pattern2 -> expression; ... «_ -> expression» | |
| select case | conditional expression |
^a This is pattern matching and is similar to select case but not the same. It is usually used to deconstruct algebraic data types.
