To display if there removed any lines, we had to create a new "file" to display added and removed lines

When adding lines to the end of a file, the 'diff' package reads it as removing and adding the last line even though there isn't any changes. This line is to ensure a \n at the end so the package can read it as unchanged line.
| function normalizeLines(str) { | ||
| const strWithNewLine = str.endsWith('\n') ? str : str + '\n'; | ||
|
|

| return strWithNewLine.split('\n').map(line => line.replace(/\s+$/, '')).join('\n'); |

This is to clear out trailing white spaces. The package has a property to ignore white spaces, but when trying to rebuild the diff file, it removed all the indentation.
