Constructs the target with the elements of specified array as the arguments and the specified constructor as the new.target value.

fun <T : Any> construct(target: JsClass<T>, argumentsList: ReadonlyArray<Any?>): T

defineProperty

fun defineProperty(target: Any, propertyKey: PropertyKey, attributes: TypedPropertyDescriptor<*>): Boolean

Adds a property to an object, or modifies attributes of an existing property.

deleteProperty

fun deleteProperty(target: Any, propertyKey: PropertyKey): Boolean

Removes a property from an object, equivalent to delete target[propertyKey], except it won't throw if target[propertyKey] is non-configurable.

get

fun get(target: Any, propertyKey: PropertyKey): Any?

Gets the property of target, equivalent to target[propertyKey] when receiver === target.

getOwnPropertyDescriptor

fun getOwnPropertyDescriptor(target: Any, propertyKey: PropertyKey): TypedPropertyDescriptor<*>

Gets the own property descriptor of the specified object. An own property descriptor is one that is defined directly on the object and is not inherited from the object's prototype.

getPrototypeOf

fun getPrototypeOf(target: Any): Any?

Returns the prototype of an object.

has

fun has(target: Any, propertyKey: PropertyKey): Boolean

Equivalent to propertyKey in target.

isExtensible

fun isExtensible(target: Any): Boolean

Returns a value that indicates whether new properties can be added to an object.

ownKeys

fun ownKeys(target: Any): ReadonlyArray<PropertyKey>

Returns the string and symbol keys of the own properties of an object. The own properties of an object are those that are defined directly on that object, and are not inherited from the object's prototype.

preventExtensions

fun preventExtensions(target: Any): Boolean

Prevents the addition of new properties to an object.

set

fun set(target: Any, propertyKey: PropertyKey, value: Any?): Boolean

Sets the property of target, equivalent to target[propertyKey] = value when receiver === target.

setPrototypeOf

fun setPrototypeOf(target: Any, proto: Any?): Boolean

Sets the prototype of a specified object o to object proto or null.
