empty(denops: Denops, expr: unknown): Promise<unknown>

Return the Number 1 if {expr} is empty, zero otherwise.

A |List| or |Dictionary| is empty when it does not have any items.
A |String| is empty when its length is zero.
A |Number| and |Float| are empty when their value is zero.
|v:false|, |v:none| and |v:null| are empty, |v:true| is not.
A |Job| is empty when it failed to start.
A |Channel| is empty when it is closed.
A |Blob| is empty when its length is zero. For a long |List| this is much faster than comparing the length with zero. Can also be used as a |method|: mylist->empty()
