# Tries to parse a JSON string and return the corresponding JSON object (Ruby hash, array, etc).
# Returns default value when fails to parse (default value is set to `nil` by default).
#
# IMPORTANT: `JSON::ParseError` is not the only exception that can be raised by `JSON.parse`.
# Check this link (`Ctrl + f' for `error'):
