Is there a name for an "array with no holes"? How would you call an array [1, 2, 3, 4, 5, ...] that has (and ensures) the property of not having any undefined values through all its length.
&quot;Dense&quot; could work but it's not exactly what I mean, as it has more to do with zero/non-zero values.
The data structure itself is unambiguously called a contiguous array. Depending on the context and language I would call it &quot;initialized&quot; or &quot;having only non-null elements&quot; or similar to describe the contents.
