Default arguments

[MaxGraey]

class Vec4 {
     constructor(x: float32 = 0, y: float32 = 0, z: float32 = 0, w: float32 = 1) { 
           ... 
     }
}

~~and class Renderer { getContext(): RenderContext? { ... } }~~

In second example did you mean optional return. In that case following is more declarative since we need either void or a type.

getContext():void|type

[MaxGraey]

Sure, in Typescript uses type|void or type|null but since TurboScript is a superset of TypeScript we can have a convenient alternative. I think declaration of optional returning type better in Swift-like manner: this representation is more compact.

Another variant:

getContext()?: RenderContext

Which more compatible form with argument optionals

[MaxGraey]

However according to this: https://github.com/Microsoft/TypeScript/issues/7426 That proposal decline in TypeScript. The main problem is to determine what is type?, it is a type | null | undefined or type | undefined which very sensitive to strict equality

getContext()?: RenderContext

If above signature means getContext return RenderContext or null we dont need ? operator since all types are nullable.

getContext(): RenderContext {
    return null;
}

above code is valid. Also optional return is not possible since at compile time there must be only one type. Multiple return types must be handled with interfaces.

We need to implement default arguments.

Ok, I got it. So I rename topic just for default arguments

Is this needed for v1, i'd vote for v2?

[nidin]

Let's move it to V2 since it's not blocking basic functionality
