// This will safely check a value to make sure it has been declared and assigned a value other than null or undefined:
console.log(typeof undeclaredVariable !== "undefined" &&
  (typeof undeclaredVariable !== "object" || !undeclaredVariable)) // false

// Compare to checking for null using ==, which will only work for declared variables:
try { undeclaredVariable == null } catch(e) { console.log(e) } // ReferenceError: undeclaredVariable is not defined
try { undeclaredVariable === null } catch(e) { console.log(e) } // ReferenceError: undeclaredVariable is not defined
try { undeclaredVariable === undefined } catch(e) { console.log(e) } // ReferenceError: undeclaredVariable is not defined

"""Set retention on slack conversations to 400 days.

Usage: ./set_retention.py [--perform] --token SLACK_TOKEN

The `--perform` flag is necessary to actually perform the action.

Due to the fact that `conversations.setToken` is not part of the public API
the slack legacy token concept will not work. To obtain the API token,
open up slack in the browser and observe networking traffic while performing
