// Using ES 6, shortest and most readable solution
(new Set(myArray)).size !== myArray.length

// Using Array.some, this is fastest solution
myArray.some((value, index, array) => array.includes(value, index + 1))

// Using filter
passphrases.filter(function (value, index, self) { return self.indexOf(value) === index; }).length !== passphrases.length

• The concept or the WHY we need this PR ?
  • Definition/Motivation/Logic
  • Define my own Test cases and compare with PR's test cases
  • Migration
• Code review, if any changes effect the logic, waiting for update, then do Code Review again
  • In the quick scan, does any code break the app
  • Need to update environment variables ? if yes, wait for update then check again
  • Need to update package.json, package-lock.json
  • Code base convention: does files structure follow the current code base convention ?
• Code base Screaming principle: does files name present its main logic ?
