Refactoring function Complexity from 22-15 and 16-15, src/install.js

[mrahmed2026]

This resolves #3
Refactored 2 different functions from their complexities (22 and 16) to a complexity of at least 15.
I broke the code down and put many of the conditional statements into different helper functions.
This in turn helped to reduce the complexity of the function, as instead of doing the complex conditional logic, it simply had to make a function call.
Hence reducing the overall complexity.
The file path is src/install.js
