The question I ask myself to this day is why they began switching to React. It made no sense at all for me. Like it was a working product, so why would you switch?
I get that new developers might be more familiar with React, but then again, as soon as the trade-offs were apparent, I would've pulled the plug.
But they said: Buckle up, everyone, let's ruin our product!
Promotion-driven development happens at Microsoft just like any other big tech company.
Hm, I didn't realise they'd moved to React. I remember reading years ago that it used jQuery for the longest time but they put in some effort to move to pure Javascript (maybe using web components).
