JSCFunction

Inherits Invokable / JSObjectUtils / Reference / Object

JSCFunction represents a JavaScript's native function(a function that run native code instead of javascript).

Constants

FUNCTIONS = [] of JSCFunction

new(func : Array(JSCPrimative | JSCFunction | JSCObject) -> _, name : String | Nil = nil, auto_save : Bool = true)

Initializes a JavaScript native function. For short, uses WebExtension.function macro instead.

NOTE: IMPORTANT. Does not directly use parameter as return value. The following code won't work.

WebExtension.function params do
  params.first # => Directly returns function parameter(s) is not recommended and may crash program
end

raise(message : String)

Raises a JavaScript Error with given message.

call(*args)

Calls the function.

E.g:

sum_function.call JSCPrimative.new(1), 2

NOTE: Calling function this way won't make JS this operator usable. In case of invoking object's method, uses Invokable#invoke instead.
