Maybe I'm unusually fortunate that a lot of day jobs I've had at one point or another gave me an opportunity to learn new tech (that wasn't the one that got me hired there). In the past 5 years I've mostly been alternating between c# & javascript/typescript.

There would be new projects & not many people in the company experienced in the tech required (due to hiring staff that has experience in their bread & butter current projects) and it was often pretty easy to jump on those ships - it does require the confidence that you'll be able to ramp up quickly!

Also when a technology is new there is a shortage of people with experience using it & companies relax experience expectations when hiring.
