Source 
pub unsafe extern "C-unwind" fn JSObjectDeletePropertyForKey(
    ctx: JSContextRef,

    property_key: JSValueRef,

) -> bool
Available on crate features JSObjectRef and JSBase only.
Expand description

Deletes a property from an object using a JSValueRef as the property key.

Parameter ctx: The execution context to use.

Parameter object: The JSObject whose property you want to delete.

Parameter propertyKey: A JSValueRef containing the property key to use when looking up the property.

Parameter exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.

Returns: true if the delete operation succeeds, otherwise false (for example, if the property has the kJSPropertyAttributeDontDelete attribute set).

This function is the same as performing “delete object[propertyKey]” from JavaScript.
