|
|
|
+<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.
