[erlang-questions] pre-map erlang, json, list of kv pairs

[t x]

Hi,

  I'm studying https://github.com/joearms/ezwebframe/blob/master/demos/clocks/clock1.html#L81-L88

  From this, I have a question:

  In per-map (i.e. before E17) erlang, when json maps are convereted
to Erlang data structures, do they become lists of key-value pairs?

  On one hand this seems weird, but on the other hand, since pre-17
Erlang doesn't have maps, how else can maps be represented?

Thanks!
