When I bang something up, I&#x27;ll use Visual Studio 2015 and Typescript from the get-go, now that I&#x27;m used to it I find it much faster due to the Intellisense on all my code, and all the browser code too (and anything else I add typings for [1]).<p>I find it way, way, way more productive than plain old JS development without an IDE.<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;DefinitelyTyped&#x2F;DefinitelyTyped" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;DefinitelyTyped&#x2F;DefinitelyTyped</a><p>EDIT: I always turn off optional any types, so everything has to be type annotated, even if that means I simply cast to an explicit &lt;any&gt;. I find that non trivial problems in JS become so much easier in TS due to the compiler and built-in refactoring tools. I can&#x27;t think of anything negative to say about TS at all!!!
