I thought I could do something like this :
<br>
<br>
write(Key, Data, Db) ->
<br>
[ {key, data} | Db ]
<br>
<br>
but then I see some error messages.
<br>

<br>
what messages?
<br>
<br>
as far as i can _theorize_
<br>
the most probably your Db is not a list, and it should be.

Here is my code so far : <br>
<br>
-module(db).<br>
<br>
-export([new/0, destroy/1]).<br>
<br>
new() -><br>
[].<br>
<br>
destroy(Db) -><br>
{ok}.<br>
<br>
write(Key, Element, Db) -><br>
[ [{key, data}] | Db ] <br>
<br>
<br>
and this the output of c(db).<br>
<br>
<input class="terminal-input">
<br>
<div data-row="4" class="terminal-row">3> c(db). </div>
<div data-row="5" class="terminal-row">db.erl:12: syntax error before: </div>
<div data-row="6" class="terminal-row">db.erl:8: Warning: variable 'Db' is unused </div>
error <br>
