return statement may appear within a for or an if.
- The only effects that a function can have are changing the likelihood, printing things, and returning an output.
- Looping allows for limited side-effects.
+- Unlike some other languages, the curly braces are mandatory in if statements (the parentheses around the condition are not).
## Working with scalar data
| Feature | Example |
|---|---|
| The basic datatypes are integer, real, boolean, and string | 42 (integer), 3.14 (real), true or false (boolean), "hello" (string) |
| The basic datatypes are integer, real, boolean, and string | 42 (Int), 3.14 (Real), true or false (Bool), "hello" (String) |
| Arithmetic on numbers | 2.0 + 3.0, 2.0 - 3.0, 2.0 * 3.0, 2.0 / 3.0 |
| Comparisons (return booleans) | 2.0 < 3.0, 2.0 <= 3.0, 2.0 == 3.0, 2.0 >= 3.0, 2.0 > 3.0 |
| Boolean logic, AND (true if both are true) | a && b |
[].
+- The basic datatypes are integer (Int), real (Real), boolean (Bool), and string (String). Each of them can be converted to a sequence by []. For instance, Int[] for a sequence of integers.
- It is not possible to change individual elements. For example: let testSeq[1] = x; // compiler error!
