Glowbal b489750d5b Minor optimizations using private, params, and isEqualType (#4323)
* Optimizations with private, params, and isEqualType

* Fixed tab being used instead of space

* Fixed tabs inserted by notepad++

* More usage of new private syntax and params

- changed a few checks for an array being empty to `_arr isEqualTo []`
rather than `count _arr == 0`
- added more uses of `private` on the same line as the variable is
declared
- added more uses of params to assign variables passed as parameters
- removed unnecessary parentheses
- removed several unnecessary variable declarations with private array
syntax

* clean up and formatting
