<dl id="order">
<dt>Q: Table iteration with <tt>pairs()</tt> does not result in the same order?</dt>
<dd>The order of table iteration is explicitly <b>undefined</b> by
the Lua language standard.<br>
Different Lua implementations or versions may use different orders for
otherwise identical tables. Different ways of constructing a table may
result in different orders, too.<br>
Due to improved VM security, LuaJIT 2.1 may even use a different order
on separate VM invocations or when string keys are newly interned.<br><br>
If your program relies on a deterministic order, it has a bug. Rewrite it,
so it doesn't rely on the key order. Or sort the table keys, if you must.
