RxQ vs. enigma.js
enigma.js is a fantastic library by the Qlik R&D team that has a similar goal to RxQ: it provides a means for working with the Qlik Associative Engine (QAE) in a scalable way. RxQ was largely inspired by the work that was done on enigma.js.
When comparing enigma.js to RxQ, our feeling is that enigma.js has a much lower learning curve and works exceptionally well for basic use cases. While RxQ has a higher learning curve due to the usage of Rx, we believe that those who use Rx via RxQ will find that it shines as you scale up to more advanced applications of QAE.
