Syntax errors are easy to correct. Its when you are working in a language that is fundamentally different like a functional language and then also an object oriented language where there could be large potential issues. Editors and linters aren't going to know enough to point out that you're "doing it wrong". My concrete example would be Ruby and Elixir. There are fundamental differences in how you design your solution because the languages are that different. It really messes with your brain for a while until you can context switch. A tip if its causing issues larger than typo's or syntax is to time-box your work in the different languages, only focusing on one at a time. Like mornings doing X and afternoons doing Y. Give your brain a break in between.
