JSAny extension type - dart:js_interop library (original) (raw)

A non-nullish JavaScript value.

A JSAny can be any JavaScript value except JavaScript null andundefined. JavaScript null and undefined are instead converted to Dartnull by the compiler. Therefore, [JSAny](../dart-js%5Finterop/JSAny-extension-type.html)? is the top type of the type hierarchy as it includes nullish JavaScript values as well.
