How to prompt a user for an expanded variable in Bash?
I work with CentOS operating system and my only shell is Bash.
I want to create a script which prompts a user with a question like "*What is your web application root?*"<br>
The user should answer directly in terminal and the answer would be stored in a variable named `web_application_root`.
I **assume** that generally the user would use variables such as `${HOME}` (envar) or `${some_medium_directory}` (non envar) in its answer, so any variable/s should be expanded.

I prefer not to use the `read` shell builtin for this because it requires `IFS` configuration which at least for now I find as an "overkill".<br>
I don't think I would mind using Node.JS, Python, Perl or any "shell-completing" programming language if I have to, I just want to have something which is working and stable.
