# Array length To get the number of elements of an array in Raku you put the array in a coercing Numeric context, or call `elems` on it. ```perl my @array = ; say @array.elems; # 2 say elems @array; # 2 say + @array; # 2 say @array + 0; # 2 ``` Watch out for infinite/lazy arrays though. You can't get the length of those. ```perl my @infinite = 1 .. Inf; # 1, 2, 3, 4, ... say @infinite[5000]; # 5001 say @infinite.elems; # Throws exception "Cannot .elems a lazy list" ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
