What helps a lot is proper IDE support for your language; it will correct you when you type the wrong thing. Other than that, I think it's just a matter of experience. The more you use them, the more you switch, the easier it gets. I recently had to switch to Java after years of mostly doing js and typescript, and though I'd done lots of Java in the past, it was a frustrating experience because there are a lot of things that ts/js just do better than Java.
