Proficiency

The first goal for a software developer is to achieve proficiency in any programming language or paradigm. Achieving a good level of proficiency is not easy, and some languages may have a steeper learning curve than others.

Problems arise when proficiency in a language ends up creating a comfort zone from which a developer or team finds it difficult to leave. In contrast, a myth must be overthrown: that one programming language is much easier than the other. Obviously, a language may prove simpler than another at first, but in the end what will count is the practice time and the number of scenarios experienced by a developer with a programming language.

Another myth that must be fought is that all languages are equal at their core and that only the syntax changes. This is one of the worst possible errors that can be committed. Languages can be quite different in internal design and performance, although they have similar syntaxes.

Proficiency is something that should be considered when deciding which language to apply for a microservice. However, it should not be as decisive as this one.
