async/await is just the do-notation of the Promise monad

CertSimple just wrote a blog post arguing ES2017's async/await was the best thing to happen with JavaScript. I wholeheartedly agree.

In short, one of the (few?) good things about JavaScript used to be how well it handled asynchronous requests. This was mostly thanks to its Scheme-inherited implementation of functions and closures. That, though, was also one of its worst faults, because it led to the "callback hell", an seemingly unavoidable pattern that made highly asynchronous JS code almost unreadable. Many solutions attempted to solve that, but most failed. Promises almost did it, but failed too. Finally, async/await is here and, combined with Promises, it solves the problem for good. On this post, I'll explain why that is the case and trace a link between promises, async/await, the do-notation and monads.

First, let's illustrate the 3 styles by implementing

Demanda :
Criar uma listview no seblod que mostrasse apenas usuarios que pertencam um grupo especifico de usuarios no joomla.
No meu sistema , eu precisava mostrar somente na list os usuarios em dia.Estes usuarios, quando em dia faziam parte do grupo chamado "Associacoes Adiplentes" cujo Group_id é 118. Toda vez que um usuario comecava a participar deste grupo, um novo registro na tabela user_usergroup_map_BDEL era atualizado.

Desta forma, criei um campo na tabela users chamado "em_dia" e fiz uma trigger na tabela user_usergroup_map que validava esta a inclusao de usuarios no grupo 118 e retornava esta validacao para a tabela users.
