Writing Functions (Uncle Bob's principles)

Some principles to write functions from Clean Code book

1. The first rule of functions is that they should be small.

2. The second rule of functions is that they should be smaller
   than that (upto 20 lines of code)

3. FUNCTIONS SHOULD DO ONE THING

4. Function Arguments

• Better if no argument

• Functions should have maximum of 2 arguments

• But arguments should not be exceeded by 3
  (They take a lot of conceptual power)

• It should has same level of abstraction
  (1 level of abstraction)

• Passing a boolean into a function is a truly terrible
  practice. (Flag as argument)
