I am working on a project using latest versions of Angular ( version 5) and Bootstrap (4).
After few weeks of developement, some features started to squawk on Safari. and I am not even sure if all features are still working as expected in IE.
As a modern frontend developer using latest javascript and css frameworks that clearly doesn't support old browsers.
Bootstrap supports the latest, stable releases of all major browsers and platforms. On Windows, we support Internet Explorer 10-11 / Microsoft Edge.
Should I care about browser compatibility ?
And If I have to care, what should I do to fix these errors ?
I am looking for recommendations to make better decisions.
