Software developer, runner and backyard chickens

Thanks to some friends, I started programming in high school with QBASIC. Nowadays, I'm a software engineer working mostly in Java and active on Exercism. On weekends, you can find me outside, at a parkrun, tending to the veggie patch or the six backyard chooks.

Some languages like Python understand this syntax (so that `1 < 2 < 3` is the same as `1 < 2 and 2 < 3`). Many others give an error. I think Javascript's behaviour is an unfortunate mistake.
