[one2code]

Inconsistencies in formatting as noted in issue #33

There's inconsistent styling across the codebase, with mixed use of ' ' and " " in several of the files

Solution

Replace all instances of ' ' with " " using the Prettier formatter, to update older files with a style that is consistent with the newer files

Describe the modifications you've done.

Result

Replaced all instances of ' ' with " " where found in the codebase under the /src folder, and it's children directories
