[BAEKJOON Online Judge + Node.js] 1181: Word sort

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' ]

After referring,

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 || a.localeCompare(b);

});

console.log(removedArr.join("\n"));

Things i was missing 

- I did't know the localeCompare(). This method returns a number indicating. By using 'localeCompare', can sort out in alphabetical order
