It's bothering me that this question even has to be asked in the first place. I'm 34. Some of my colleagues are 40+ and very effective hackers, getting things done on time, not getting lost in configuring webpack, pragmatic, but also getting quickly and deeply into the JS framework du jour. I actively work with one or two new technologies every year, for real money, adding it up to the current stack of things we maintain. No time for side projects currently due to kids, but my work projects are interesting enough.
