Unfortunately the quality level of the comments for this presentation makes me very sad.
Some guys at Microsoft are trying to make your life easier and to give you the needed free time to go home to your family and play with your kids instead of spending hours at work to write JS code and you are not grateful – worst, you despite them.
No problem my dears, spend your life in front of PC and ignore your child and family. Have a long life like prisoners in a small room writing tone of code lines!!!
I will use any tool that will give me 1 free hour to live my life.
