preserveWhitespace not working for code block

[victory-sokolov]

Hey! I was wondering if should I create a custom translator in order to preserveWhitespace for code blocks.
As for now, code blocks are missing whitespaces on the new line, here is the current result that I'm getting.

   public async writeFile(filePath: string, contents: string) {
   writeFile(filePath, data, err => {

    if (err) {
    throw err;
    }

    console.log("JSON data is saved.");
    });
    }

or should we add a new case statement for the code block in the visitNode method?
