v-zo / BackboneJS API fetch and parse

Created February 1, 2019 14:15 — forked from daniel-234/BackboneJS API fetch and parse

BackboneJS - Fetch data from an API and parse the response populating models inside a collection

	About this gist

	With this gist I wanted to freeze some concepts about BackboneJS that could
	save some time in the future either to me if I needed to use this functionality
	again, or to somebody else.

	This implementation addresses the need to retrieve some data from an API and
	to populate a BackboneJS collection accordingly, storing the retrieved items
	as Models inside the Collection.
	If you want to see this functionality built into an application, have a look
