This returns the equivalent of Object.getPrototypeOf (which is not the same as the function’s prototype property).

sourcepub fn define_properties(&mut self, properties: &[Property]) -> Result<()>
pub fn define_properties(&mut self, properties: &[Property]) -> Result<()>
This method allows the efficient definition of multiple properties on a given object.
sourcepub fn get_array_length(&self) -> Result<u32>
pub fn get_array_length(&self) -> Result<u32>
Perform is_array check before get the length
if Object is not array, ArrayExpected error returned
sourcepub fn get_array_length_unchecked(&self) -> Result<u32>
pub fn get_array_length_unchecked(&self) -> Result<u32>
use this API if you can ensure this Object is Array
