I've been learning .Net for work, which isn't too challenging. But after working with JavaScript for a year, having to use Pascal Case is the most annoying difference between the two languages.

Even after a few weeks working in C#, I still find it unintuitive to to write my methods and properties LikeThis (Pascal Case) and not likeThis (Camel Case). It's such a small change, but it still gets me.

What has been the most irritating differences for you when switching between languages or between stacks?

It's really the little things that make all the difference.
