BQN tries to maintain a "default" element for every array, known as a fill element, for this purpose. If it's known, the fill element is a nested array structure where each atom is either <code><span class='Number'>0</span></code> or <code><span class='String'>' '</span></code>. If no fill is known, a function that requests it results in an error.</p> <p>Fills are used by <a href="take.html">Take</a> (<code><span class='Function'>โ</span></code>) when a value in <code><span class='Value'>๐จ</span></code> is larger than the corresponding length in <code><span class='Value'>๐ฉ</span></code>, by the two <a href="shift.html">Nudge</a> functions (<code><span class='Function'>ยปยซ</span></code>) when <code><span class='Value'>๐ฉ</span></code> is non-empty, by <a href="couple.html">Merge</a> (<code><span class='Function'>></span></code>) when <code><span class='Value'>๐ฉ</span></code> is empty, and by <a href="reshape.html">Reshape</a> (<code><span class='Function'>โฅ</span></code>) when <code><span class='Value'>๐จ</span></code> contains <code><span class='Function'>โ</span></code>. Except for these specific cases, the fill value an array has can't affect the program. The result of <a href="match.html">Match</a> (<code><span class='Function'>โก</span></code>) doesn't depend on fills, and any attempt to compute a fill can't cause side effects.</p> |
