// any unicode letter/number is valid for names in go - don't use them

// snake_case is rarely used, use camelCase

// prefer shorter names, k,v for key,value in for loops etc

// if using single letter var names, you can follow the type. E.g i for int, b for bool

// when naming vars/consts in the package level, favour more descriptive names
// !!! the smaller the scope of the variable, the shorter the name !!!
