pub fn to_string(
    this: &JsValue,
    _: &[JsValue],
    context: &mut Context

pub fn has_own_property(
    this: &JsValue,
    args: &[JsValue],
    context: &mut Context
) -> JsResult<JsValue>

Object.prototype.hasOwnPrototype( property )

The method returns a boolean indicating whether the object has the specified property as its own property (as opposed to inheriting it).

More information:

• ECMAScript reference

pub fn property_is_enumerable(
    this: &JsValue,
    args: &[JsValue],
    context: &mut Context

• ECMAScript reference
• MDN documentation

pub fn keys(
    _: &JsValue,
    args: &[JsValue],
    context: &mut Context
) -> JsResult<JsValue>

Object.keys( target )

This method returns an array of a given object’s own enumerable property names, iterated in the same order that a normal loop would.

More information:

• ECMAScript reference
• MDN documentation

pub fn values(
    _: &JsValue,
    args: &[JsValue],

• MDN documentation

pub fn entries(
    _: &JsValue,
    args: &[JsValue],
    context: &mut Context
) -> JsResult<JsValue>

Object.entries( target )

This method returns an array of a given object’s own enumerable string-keyed property [key, value] pairs. This is the same as iterating with a for…in loop, except that a for…in loop enumerates properties in the prototype chain as well).

More information:

• ECMAScript reference
• MDN documentation
