# Datatypes |
||||
|
||||
> **Note:** Due to the fact that Sabre currently emits javascript, static types are not needed, as of yet. They will however be introduced soon, once a statically typed backend is used. |
||||
|
||||
## The Integer type |
||||
|
||||
The `integer` datatype represents a number. The JavaScript backend interprets any integer as a `Number` type. |
||||
|
||||
``` |
||||
fn main() { |
||||
let sum = 1 + 2 |
||||
println("1 + 2 is ", sum) |
||||
} |
||||
``` |
||||
|
||||
``` |
||||
$ sabre build main.sb -o main.js |
||||
$ node main.js |
||||
1 + 2 is 3 |
||||
``` |
||||
|
||||
## The String type |
||||
|
||||
A string is a sequence of characters. |
||||
|
||||
``` |
||||
fn main() { |
||||
let name = "Jon" |
||||
println("Hello " + name) |
||||
} |
||||
``` |
||||
|
||||
``` |
||||
$ sabre build main.sb -o main.js |
||||
$ node main.js |
||||
Hello Jon |
||||
``` |
||||
|
||||
## The Array type |
||||
|
||||
Arrays represent a sequence of values. They can hold any number of values of a specific type. |
||||
|
||||
> **NOTE:** Currently, there is no type-checking involved when creating arrays. There will be, once a type system is in place, so don't get too attached to mixing and matching element types. ;) |
||||
|
||||
``` |
||||
fn main() { |
||||
let fruits = ["Banana", "Apple", "Pineapple"] |
||||
|
||||
for fruit in fruits { |
||||
println(fruit) |
||||
} |
||||
} |
||||
``` |
||||
|
||||
``` |
||||
$ sabre build main.sb -o main.js |
||||
$ node main.js |
||||
Banana |
||||
Apple |
||||
Pineapple |
||||
``` |
