#mizchi/js/builtins/reflect

Reflection API with JavaScript's Reflect object.

#Installation

Add to your moon.pkg.json:

{
  "import": [
    "mizchi/js",
    "mizchi/js/builtins/reflect"
  ]
}

#Overview

Provides bindings for JavaScript's Reflect API for intercepting JavaScript operations.

#Usage Example

fn main {
  let obj = @core.Object::new()

  // Set property
  @reflect.set(obj, "name", "value")

  // Get property
  let value = @reflect._get(obj, "name")

  // Has property
  let has = @reflect.has(obj, "name")  // true

  // Delete property
  @reflect.delete_property(obj, "name")
}

#Available Methods

  • get(target, key) - Get property value
  • set(target, key, value) - Set property value
  • has(target, key) - Check if property exists
  • deleteProperty(target, key) - Delete property
  • ownKeys(target) - Get all own property keys

JavaScript Reflect API https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Reflect

#
Reflect::apply

source

JS: Reflect.apply(target, thisArgument, argumentsList) Calls a target function with arguments as specified

#
Reflect::construct

source

JS: Reflect.construct(target, argumentsList, newTarget?) Acts like the new operator as a function

#
Reflect::defineProperty

source
fn Reflect::defineProperty(target : 
Any, property_key : 
Any, attributes : 
Any) -> Bool

JS: Reflect.defineProperty(target, propertyKey, attributes) Similar to Object.defineProperty but returns a Boolean

#
Reflect::deleteProperty

source
fn Reflect::deleteProperty(target : 
Any, property_key : 
Any) -> Bool

JS: Reflect.deleteProperty(target, propertyKey) Deletes a property from an object

#
Reflect::get

source

JS: Reflect.get(target, propertyKey, receiver?) Gets a property value from an object

#
Reflect::getOwnPropertyDescriptor

source
fn Reflect::getOwnPropertyDescriptor(target : 
Any, property_key : 
Any) -> 
Any

JS: Reflect.getOwnPropertyDescriptor(target, propertyKey) Gets the property descriptor of an own property

#
Reflect::getPrototypeOf

source
fn Reflect::getPrototypeOf(target : 
Any) -> 
Any

JS: Reflect.getPrototypeOf(target) Gets the prototype of an object

#
Reflect::has

source
fn Reflect::has(target : 
Any, property_key : 
Any) -> Bool

JS: Reflect.has(target, propertyKey) Checks if an object has a property

#
Reflect::isExtensible

source
fn Reflect::isExtensible(target : 
Any) -> Bool

JS: Reflect.isExtensible(target) Checks if an object is extensible

#
Reflect::ownKeys

source

JS: Reflect.ownKeys(target)

Returns an array of the target object's own property keys. Note: The returned array is a snapshot and should be treated as immutable.

#
Reflect::preventExtensions

source
fn Reflect::preventExtensions(target : 
Any) -> Bool

JS: Reflect.preventExtensions(target) Prevents new properties from being added to an object

#
Reflect::set

source
fn Reflect::set(target : 
Any, property_key : 
Any, value : 
Any, receiver : 
Any?) -> Bool

JS: Reflect.set(target, propertyKey, value, receiver?) Sets a property value on an object

#
Reflect::setPrototypeOf

source
fn Reflect::setPrototypeOf(target : 
Any, prototype : 
Any) -> Bool

JS: Reflect.setPrototypeOf(target, prototype) Sets the prototype of an object
