callAsFunction(this:_:)
@discardableResult
public func callAsFunction(this: JSObject? = nil, _ arguments: ConvertibleToJSValue...) throws -> JSValue A variadic arguments version of callAsFunction.
new(arguments:)
public func new(arguments: [ConvertibleToJSValue]) throws -> JSObject Instantiate an object from this function as a throwing constructor.
Guaranteed to return an object because either:
-
a. the constructor explicitly returns an object, or
-
b. the constructor returns nothing, which causes JS to return the
thisvalue, or -
c. the constructor returns undefined, null or a non-object, in which case JS also returns
this.
Parameters
| Name | Type | Description |
|---|---|---|
| arguments | [ConvertibleToJSValue] |
Arguments to be passed to this constructor function. |
Returns
A new instance of this constructor.
new(_:)
public func new(_ arguments: ConvertibleToJSValue...) throws -> JSObject A variadic arguments version of new.
