IE 11 supports source maps, so that&#x27;s helpful. The other nice thing is that you rarely end up dealing with browser specific quirks since all popular ClojureScript libraries piggie back on React.js and the Google Closure library.<p>These do a great job of handling the platform specific quirks for you. The first app I developed with Reagent actually had to run on IE8, and to my shock and surprised worked without any issues after I added the standard IE shims.<p>So, overall my experience is that you&#x27;re better off dealing with IE than with most Js frameworks.
