The foreign language requirement tends to push up the age when we start coding. I could read Finnish before I started school. Getting to a decent level of reading English took a dozen years on top of that. Sure, I was cargo-culting some code in the meantime, but reading the APIs and documentation was difficult.
Even more important than delaying learning, the foreign language requirement also impedes learning. If you want to program but aren't super hot at languages, the foreign language may well make you skip the whole thing. But if the programming language is speaking your language, maybe you'll give it a go.
Programming in a second language isn't just a hurdle for learning, it also slows you down. You can't think as fast in a non-native language. If your brain's running in Finnish, thinking about code in English is like running emulated code.
First, add the JS-i18n script to your page:
<script type="text/js-i18n"> "lang fi"; hälytä("Terve maailma!"); </script>
