IE 10 will default to edge mode regardless of this directive if used with a HTML5 doctype, except in certain circumstances (intranet sites). I suspect that we left most of the enviroments where such circumstances exist behind when we dropped IE9. In IE11, "document modes are deprecated and should no longer be used". |

Yup @bardiharborow . This might be a bold move for some but this should be taken as we should remove any crutches behind which are of no use for the new, modern and flexibile web !!! |

See twbs/bootstrap#21476 and https://stackoverflow.com/q/6771258 for a thorough overview. From the looks of it, this tag isn't needed for IE 10+, and IE 10 is the oldest version of IE that the dependencies of the viewer interface support as of writing (per https://github.com/farbelous/bootstrap-colorpicker/issues/271). So there's no need to include this tag. Also for posterity here's a list of all of the IE version support for the viewer interface's current dependencies (I was going to include this in a comment in the viewer interface that justified keeping the tag in, but then I realized that this tag wasn't even needed for IE 10 so I scrapped the comment) -- d3 v4: IE9+ (https://github.com/d3/d3/wiki#supported-environments) Cytoscape.js: IE9+ [supports canvas and most of ECMAScript 5] (http://js.cytoscape.org/#introduction/factsheet) jQuery: IE9+ (https://jquery.com/browser-support/) bootstrap 3: IE 8-11 (https://getbootstrap.com/docs/3.3/getting-started/#support) bootstrap colorpicker: IE >= 10 (https://github.com/farbelous/bootstrap-colorpicker/issues/271) Couldn't find much data on sql.js browser support aside from that old browsers probably aren't a good idea with it, so using IE in general with sql.js is probably not feasible. (See: https://github.com/kripken/sql.js/issues/238, https://github.com/kripken/sql.js/issues/239)

With dropping of IE9,
I think there is no need now for the below code so please remove this from starter template
<meta http-equiv="X-UA-Compatible" content="IE=Edge">Source: http://stackoverflow.com/a/6771584
( Same link that @mdo posted in his codeguide )
