Readability, efficiency, maintainability, and usability

Readability, efficiency, maintainability, and usability are all critical factors to consider when writing code.

Readability

Readability refers to the ease with which a human reader can understand a piece of code. Well-written code is easy to read, with clear and concise statements that are organized in a logical and consistent manner. This becomes very important if we consider that developers spend ten times more time reading code than writing it.

Let’s take a look at the following piece of code:

class Employee {

  uint64_t getId() const;
};
