bookNaming Conventions

We considered the 'technical' side of naming variables in the previous chapter. At the same time, there are several conventions among programmers in regard to naming. These are:

  • Variables’ names should be lowercase.
  • For variables’ names that contain several words, we should separate these words with the underscore characters (_).

These rules are not compulsory, but they are recommended. For example, if you need to store the number of a user's points, it will be much better to use points, num_of_points, or n_points instead of n, p, or something like that.
