daScript is high-performance strong statically typed scripting language, with

• no garbage collection,
• "pure" stateless (it's state survives only one script run)
• "native" machine types (no nan-tagging or anything)
• explicit structs
• cheap "inter-op"

In a real world scenario, it's 10+ times faster than lua-jit without JIT (and even faster than liajit with JIT). It also allows Ahead-of-Time compilation, which is not only possible on all platforms (unlike JIT), but also always faster/not-slower (JIT is known to sometimes slow down scripts).

It's philsophy is build around modified Zen of Python.

• Performance counts.
• But not at the cost of safety.
• Readability counts.
• Explicit is better than implicit.
• Simple is better than complex.
• Complex is better than complicated.
• Flat is better than nested.

Typical Fibonacci sample: def fibR(n) if (n < 2) return n else return fibR(n - 1) + fibR(n - 2)

def fibI(n) let last = 0 let cur = 1 for i in range(0, n-1) let tmp = cur cur += last last = tmp return cur

More complicated particles kinematics:

struct NObject position, velocity : float3

def updateParticles(objects:array) for obj in objects obj.position += obj.velocity

def initParticles(objects:array) resize(objects, 50000) let index = 0 for obj in objects let oi = float(index++) let ii = oi*2.0 obj.position=float3(oi+0.1,oi+0.2,oi+0.3) obj.velocity=float3(1.0,2.0,3.0) assert(index==length(objects))

def test() let objects:array initParticles(objects) updateParticles(objects,100)

It's (not)full list of features includes:

• strong typing
• Ruby-like blocks
• tables
• arrays
• string-builder
• native (c++ friendly) interop
• generics
• ECS-friendly interop
• etc, etc
