Microsoft's Edge browser was their take on the modern web. With the EdgeHTML renderer and the Chakra JavaScript engine, it performs well in many benchmarks. While the Chakra engine does have different optimizations for it than Chrome or Firefox, it is an interesting browser to look at from a pure JavaScript perspective.
In terms of features, Edge is light compared to the other browsers. If we need to perform any type of performance testing for it, the best bet is to profile code with jsPerf or others instead of the built-in tools. On top of this, the Chakra engine utilizes different optimization techniques, so what may work with Chrome or Safari may be less optimized for Edge. To get to the developer tools on Windows, we can press F12. This will pull up the usual console dialog, shown as follows:
We will not be going through any interesting features specific to Edge since most, if not all, of the features in their developer tools are the same as those found in other browsers.
