The typings for LoDash is missing transform in the LoDashExplicitObjectWrapper and LoDashExplicitArrayWrapper interfaces.
When using the following code:
_.chain(someObject)
.transform(<someParams>)
.value();
... I get the following compiler error:
Property 'transform' does not exist on type 'LoDashExplicitObjectWrapper<Object>'
As per the Lodash docs, transform should be available to be chained.
