  I did't use while loop that much so didn't come up what to do. While loop create a loop that execute a specific statement. So, the main point of this problem is "prevNum + max * 6" input = 13, output = 3 https://www.acmicpc.net/problem/2292 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/while const input = require ( "fs" ). readFileSync ( "/dev/stdin" ). toString () ; let count = 1 ; let max = 1 ; // set the range while (max < input) { max += count * 6 ; count ++ ; } console . log (count) ; // prevNum + count * 6 // 1 so +6 every loop! // 2 - 7, 5 // 8 - 19, 11 // 20 - 37, 17 // 38 - 61, 23

This is my first attempt  const input = require ( "fs" ). readFileSync ( "/dev/stdin" ). toString (). split ( " \n " ) ; const count = Number (input[ 0 ]) ; // 13 // 1. shortest word.length // 2. If the length is the same, in alphabetical order // sort() ? let newArr = [] ; // insert all elements in array let shortest = input[ 1 ]. length ; // just initial value for ( let i = 1 ; i <= count ; i ++ ) { newArr . push (input[i]) ; } // remove duplicated elements in array let removedArr = newArr . filter ( ( item , index ) => newArr . indexOf (item) === index) ; removedArr . sort ( ( a , b ) => { return a . length - b . length ; } ) ; console . log (removedArr) ; i cannot get the correct answer as my answer keeps mixing the order like  [  'i',  'no',  'it',  'im',  'but',  'wont',  'more',  'wait',  'yours', 'cannot',  'hesitate' ...

 JavaScript Patterns  1. Module & Revealing Module pattern  // STANDARD MODULE PATTERN - private/public variable const UICtrl = ( function () { let text = "Hello world" ; const changeText = function () { const element = document . querySelector ( "h1" ) ; element .textContent = text ; }; // public which is accessible from outside return { callChangeText : function () { changeText () ; console . log (text) ; } , }; } )() ; UICtrl . callChangeText () ; 2. Singleton pattern  it can only return one instance of an object at a time  3. Factory pattern Creating an interface for creating objects  MVC Pattern  It is consist of with following Model, View, Controller.  M odel take responsibility for data(application info) like data structure.  V iew represent for UI.  C ontroller is like a bridge between Model and View. They don't know each other. So it does monitor the change of Model ...
