I’ve heard “it’s easy to switch to a new language, it’s just a language, you just learn a new syntax”.
Well, I partially disagree. While you’ll may be able to learn the syntax fast, each language has its own particularities that you don’t just understand in a few days. Some languages have other best practices than others.
I believe that if you jump on writing code in a new language without understanding its philosophy, you’ll miss a lot of edge cases that we’ll lead to undesired situations. Most probably no one will die, but time will be lost.
“I took a look at Go and it’s trivial” – And a few months later you’ll end up tangled in your own work, refactoring each step.
While onboarding to the new project you have with that new language, I suggest reading the docs, understanding the language’s best use, maybe right from the authors.
