Making the most out of JavaScript Intellisense in VS2012

on 18 Sep 2012

Intellisense for JavaScript has always felt to me like an unfinished addition to Visual Studio, something that promises so much but doesn't deliver for larger projects. Manually adding and then maintaining another set of dependency references just for Intellisense has just never seemed worth it. However, with the launch...
