I have the array as below,

let Ã‚Â yearAndMonth Ã‚Â = Ã‚Â [
 "year": 2013, "month": "FEBRUARY" ,
 "year": 2015, "month": "MARCH" ,
 "year": 2013, "month": "JANUARY" ,
 "year": 2015, "month": "FEBRUARY" 
]

I want to sort the array by year first and after that sort month from the year,

I want the output like this,

yearAndMonth Ã‚Â = Ã‚Â [
 "year": 2013, "month": "JANUARY " ,
 "year": 2013, "month": "FEBRUARY" ,
 "year": 2015, "month": "FEBRUARY" ,
 "year": 2015, "month": "MARCH" 
]

How to achieve this?

You can also use lodash library for sorting data by multiple column.

I have created a demo on Stackblitz. I hope this will help/guide to you/others.

lodash - Documentation

Component.html

<table width="100%">
 <tr>
 <td>Year</td>
 <td>Month</td>
 </tr>
 <tr *ngFor="let datas of sortedData">
 <td>datas.year</td>
 <td>datas.month</td>
 </tr>
</table>

Component.ts

 sortedData: any;
 data = [
 "year": 2013, "month": "FEBRUARY" ,
 "year": 2015, "month": "MARCH" ,
 "year": 2013, "month": "JANUARY" ,
 "year": 2013, "month": "MARCH" ,
 "year": 2013, "month": "APRIL" ,
 "year": 2015, "month": "FEBRUARY" 
 ];

monthArray: any = ["JANUARY", "FEBRUARY", "MARCH", "APRIL", "MAY", "JUNE",
 "JULY", "AUGUST", "SEPTEMBER", "OCTOBER", "NOVEMBER", "DECEMBER"];

 ngOnInit() 
 this.sortedData = _.orderBy(data, [(datas) => datas.year, (user) => (this.monthArray.indexOf(user.month))], ["asc", "asc"]);
 console.log(this.sortedData);

Rather than importing an entire library to do a basic thing like sorting, try Vanilla JS: data.sort(function(a,b) (monthArray.indexOf(a.month) - monthArray.indexOf(b.month));)

@NiettheDarkAbsol I agree it's overkill, but if he is using the library already for other purposes, _.orderBy() is also simple.

You could take an object for the month names and their numerical value.

The chain the order by taking the delta of year and month.

var array = [ year: 2013, month: "FEBRUARY" , year: 2015, month: "MARCH" , year: 2013, month: "JANUARY" , year: 2015, month: "FEBRUARY" ];

array.sort(function (a, b) 
 var MONTH = JANUARY: 0, FEBRUARY: 1, MARCH: 2, APRIL: 3, MAY: 4, JUNE: 5, JULY: 6, AUGUST: 7, SEPTEMBER: 8, OCTOBER: 9, NOVEMBER: 10, DECEMBER: 11 ;
 return a.year - b.year );

console.log(array);

You can make a map which maps the Month to the month number and then use Arrays.sort() with your own custom comparator :

let months = 'JANUARY' : 1, 'FEBRUARY' : 2, 'MARCH' : 3, 'APRIL' : 4, 'MAY' : 5, 'JUNE' : 6, 'JULY' : 7, 'AUGUST' : 8, 'SEPTEMBER' : 9, 'OCTOBER' : 10, 'NOVEMBER' : 11, 'DECEMBER' : 12 ;
let yearAndMonth = [ "year": 2013, "month": "FEBRUARY" , "year": 2015, "month": "MARCH" , "year": 2013, "month": "JANUARY" , "year": 2015, "month": "FEBRUARY" ];

yearAndMonth.sort((a,b)=> a.year - b.year || months[a.month.toUpperCase()] - months[b.month.toUpperCase()]);

console.log(yearAndMonth);

You can create an array for months names and sort like this:

let data = [
 "year": 2013, "month": "FEBRUARY" , "year": 2015, "month": "MARCH" ,
 "year": 2013, "month": "JANUARY" , "year": 2015, "month": "FEBRUARY" 
];

let months = ["JANUARY", "FEBRUARY", "MARCH", "APRIL", "MAY", "JUNE",
 "JULY", "AUGUST", "SEPTEMBER", "OCTOBER", "NOVEMBER", "DECEMBER"];

data.sort(
 (a, b) => (a.year - b.year) || (months.indexOf(a.month) - months.indexOf(b.month))
);


console.log(data);

Since you are ok with using lodash this can be achived by a simple sortBy

_.sortBy(yearAndMonth, a => new Date(1+ a.month + a.year))

It will construct a new Date for each month and year (with date 1) and that should work the way you want.

let yearAndMonth = [
 "year": 2013, "month": "FEBRUARY" ,
 "year": 2015, "month": "MARCH" ,
 "year": 2013, "month": "JANUARY" ,
 "year": 2015, "month": "FEBRUARY" 
]

let res = _.sortBy(yearAndMonth, a => new Date(1 + a.month + a.year));
console.log('Sorted Result: ', res);

.as-console-wrapper max-height: 100% !important; top: 0;

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>

Note: You do not need to have array/object/map of all the months for this to have a look up to perform > or <

@AniketAvhad either use [1, a.month, a.year].join('') or use simply with + operator without array, I have edited accordingly, you faced the problem of type checking at compile time.

Declaring the month names in an array to get the relative value of the month string when comparing with each other.

First comparison will be on the year, if both the year values are same then proceeding with the month comparison based on the months array created.

let months = ["JANUARY", "FEBRUARY", "MARCH", "APRIL", "MAY", "JUNE",
 "JULY", "AUGUST", "SEPTEMBER", "OCTOBER", "NOVEMBER", "DECEMBER"];



yearAndMonth.sort((a,b) =>
 if(a.year > b.year) return 1;
 else if(a.year < b.year) return -1;
 else 
 if(months.indexOf(a.month.toUpperCase()) > 
 months.indexOf(b.month.toUpperCase()))
 return 1;
 else if(months.indexOf(a.month.toUpperCase()) < 
 months.indexOf(b.month.toUpperCase())) 
 return -1
 else return 0;
 
);

Allow me to provide a plain ES version (sort array of objects on 1 or more key values, serial dependant (sort on 1, sort 2 within 1, sort on 3 within 1 and 2 etc.), non mutating, i.e. keep the original array as is):

const log = (...str) => 
 document.querySelector("pre").textContent += `$str.join("n")n`;
const data = getData();
const xSort = XSort();
const months = [ "JANUARY", "FEBRUARY", "MARCH", "APRIL", "MAY", "JUNE",
 "JULY", "AUGUST", "SEPTEMBER", "OCTOBER", "NOVEMBER", "DECEMBER" ];

log( JSON.stringify(
 xSort
 .create(data)
 .orderBy( key: "year", key: v => months.indexOf(v.month) ),
 null,
 " ")
 );

function XSort() 
 const multiSorter = sortKeys => 
 const Sorter = function (array) 
 this.array = array;
 ;

 Sorter.prototype = 
 orderBy: function(...sortOns) 
 return this.array.slice().sort(multiSorter(sortOns));
 ,
 ;

 return 
 create: array => new Sorter(array)
 ;


function getData() 
 return [
 "year": 2013,
 "month": "FEBRUARY",
 ,
 
 "year": 2015,
 "month": "MARCH",
 ,
 
 "year": 2015,
 "month": "SEPTEMBER",
 ,
 
 "year": 2013,
 "month": "JANUARY",
 ,
 
 "year": 2013,
 "month": "MARCH",

 "year": 2013,
 "month": "APRIL",

You could take an object for the month names and their numerical value.

The chain the order by taking the delta of year and month.

var array = [ year: 2013, month: "FEBRUARY" , year: 2015, month: "MARCH" , year: 2013, month: "JANUARY" , year: 2015, month: "FEBRUARY" ];

array.sort(function (a, b) 
 var MONTH = JANUARY: 0, FEBRUARY: 1, MARCH: 2, APRIL: 3, MAY: 4, JUNE: 5, JULY: 6, AUGUST: 7, SEPTEMBER: 8, OCTOBER: 9, NOVEMBER: 10, DECEMBER: 11 ;

You could take an object for the month names and their numerical value.

The chain the order by taking the delta of year and month.

var array = [ year: 2013, month: "FEBRUARY" , year: 2015, month: "MARCH" , year: 2013, month: "JANUARY" , year: 2015, month: "FEBRUARY" ];

array.sort(function (a, b) 
 var MONTH = JANUARY: 0, FEBRUARY: 1, MARCH: 2, APRIL: 3, MAY: 4, JUNE: 5, JULY: 6, AUGUST: 7, SEPTEMBER: 8, OCTOBER: 9, NOVEMBER: 10, DECEMBER: 11 ;
 return a.year - b.year );

console.log(array);

You can make a map which maps the Month to the month number and then use Arrays.sort() with your own custom comparator :

let months = 'JANUARY' : 1, 'FEBRUARY' : 2, 'MARCH' : 3, 'APRIL' : 4, 'MAY' : 5, 'JUNE' : 6, 'JULY' : 7, 'AUGUST' : 8, 'SEPTEMBER' : 9, 'OCTOBER' : 10, 'NOVEMBER' : 11, 'DECEMBER' : 12 ;
let yearAndMonth = [ "year": 2013, "month": "FEBRUARY" , "year": 2015, "month": "MARCH" , "year": 2013, "month": "JANUARY" , "year": 2015, "month": "FEBRUARY" ];

yearAndMonth.sort((a,b)=> a.year - b.year || months[a.month.toUpperCase()] - months[b.month.toUpperCase()]);

console.log(yearAndMonth);

You can create an array for months names and sort like this:

let data = [
 "year": 2013, "month": "FEBRUARY" , "year": 2015, "month": "MARCH" ,
 "year": 2013, "month": "JANUARY" , "year": 2015, "month": "FEBRUARY" 
];

let months = ["JANUARY", "FEBRUARY", "MARCH", "APRIL", "MAY", "JUNE",
 "JULY", "AUGUST", "SEPTEMBER", "OCTOBER", "NOVEMBER", "DECEMBER"];

data.sort(
 (a, b) => (a.year - b.year) || (months.indexOf(a.month) - months.indexOf(b.month))
);

Since you are ok with using lodash this can be achived by a simple sortBy

_.sortBy(yearAndMonth, a => new Date(1+ a.month + a.year))

It will construct a new Date for each month and year (with date 1) and that should work the way you want.

let yearAndMonth = [
 "year": 2013, "month": "FEBRUARY" ,
 "year": 2015, "month": "MARCH" ,
 "year": 2013, "month": "JANUARY" ,
 "year": 2015, "month": "FEBRUARY" 
]

let res = _.sortBy(yearAndMonth, a => new Date(1 + a.month + a.year));
console.log('Sorted Result: ', res);

.as-console-wrapper max-height: 100% !important; top: 0;

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.min.js"></script>

Declaring the month names in an array to get the relative value of the month string when comparing with each other.

First comparison will be on the year, if both the year values are same then proceeding with the month comparison based on the months array created.

let months = ["JANUARY", "FEBRUARY", "MARCH", "APRIL", "MAY", "JUNE",
 "JULY", "AUGUST", "SEPTEMBER", "OCTOBER", "NOVEMBER", "DECEMBER"];



yearAndMonth.sort((a,b) =>
 if(a.year > b.year) return 1;
 else if(a.year < b.year) return -1;
 else 
 if(months.indexOf(a.month.toUpperCase()) > 
 months.indexOf(b.month.toUpperCase()))
 return 1;
 else if(months.indexOf(a.month.toUpperCase()) < 
 months.indexOf(b.month.toUpperCase())) 
 return -1
 else return 0;
