Struct rquickjs_core::Array

#[repr(transparent)]
pub struct Array<'js>(_);

Rust representation of a javascript object optimized as an array.

Javascript array’s are objects and can be used as such. However arrays in quickjs are optimized when they do not have any holes. This value represents such a optimized array.
