Handle types often represent an 'object' within the game (units, players, special effects, etc.). Handle types, however, behave more like objects. The native types behave very similarly to primitive types in other programming languages.

string (limit is 1023 signs, actually to provide save/load compatibility it's required to use only 1013 signs)ДЄll other types are considered non-native.

real (32-bit floating point numbers, similar to the float type in Java).

JASS is statically-typed, and its types can be separated into two classes: natives and handles.

JASS primarily uses procedural programming concepts, though popular user-made mods to Blizzard's World Editor program have since added C++-like object-oriented programming features to the syntax of JASS. It has a syntax similar to Turing and Delphi, although, unlike those languages, it is case sensitive. JASS can also create powerful functions such as trackables, which detects if a mouse goes over or hits a position, GetLocalPlayer(), which can cause disconnectsВ if used improperly (such as using handles with GetLocalPlayer(). It can, for example, execute simple GUI functions such as, giving orders to units, change the weather and time of day, play sounds and display text to the player, and manipulate the terrain.

The language provides an extensive API that gives programmers control over nearly every aspect of the game world.
