+# 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
