As a 40-year-old front-end dev with a decade-old work history in this space (and many more years as a hobbyist), I have not yet knowingly been on the receiving end of age-based discrimination. I expect that may change unless I start building my personal brand as a leader in this space - someone whose articles devs read and whose presentations they watch. And that would have to coincide with a change of direction in my career to one of leadership. I don’t think I should still be coding full-time when I’m 50. Over the last decade, I’ve noticed a gradual physical decline (although I’m reasonably healthy) and being an overly enthusiastic dev can take its toll. (I don’t know how to consistently cruise through my tasks and clock off at 5:30 like other devs.)
