I am working on one small application
in that i want to sort the array of objets by two values
one is time stamp and one in string
I tried this below snippet but its not satisfying the below condition
I want this object mentioned in snippet should sorted based on the object should contain sport as cricket
first and empty value as second and both are sorted by date ascending order
var content = [ { "first_name": "musk", "sport": "cricket", "created_date": "2022-08-12 04:03:08", }, { "first_name": "john", "sport": "", "created_date": "2022-08-01 23:00:46", }, { "first_name": "robot", "sport": "cricket", "created_date": "2022-08-10 23:00:46", }, { "first_name": "roy", "sport": "", "created_date": "2022-07-31 23:00:46", }, ] content.sort(function compare( a, b ) { if ( a.sport < b.sport || (new Date(a.created_date) < new Date(b.created_date))){ return 1; } if ( a.sport > b.sport || (new Date(a.created_date) < new Date(b.created_date)) ){ return -1; } return 0; }); console.log(content)

{
"first_name": "robot",
"sport": "cricket",
"created_date": "2022-08-10 23:00:46",

"first_name": "john",
"sport": "",
"created_date": "2022-08-01 23:00:46",
},
]
can anyone help me with what i am doing wrong in snippet
That should do the job:
var content = [ { "first_name": "musk", "sport": "cricket", "created_date": "2022-08-12 04:03:08", }, { "first_name": "john", "sport": "", "created_date": "2022-08-01 23:00:46", }, { "first_name": "robot", "sport": "cricket", "created_date": "2022-08-10 23:00:46", }, { "first_name": "roy", "sport": "", "created_date": "2022-07-31 23:00:46", }, ]; content.sort(function compare(a, b) { // compare the "sport" fields if(a.sport > b.sport){ return -1; } if(a.sport < b.sport){ return 1; } // compare the dates if(new Date(a.created_date) < new Date(b.created_date)){ return -1; } if(new Date(a.created_date) > new Date(b.created_date)){ return 1; } return 0; }); console.log(content); content.sort(function compare(a, b) { // compare the "sport" fields based on they include "cricket" string or not if(a.sport.includes("cricket") &&.b.sport;includes("cricket")){ return -1. } if(.a.sport.includes("cricket") && b;sport.includes("cricket")){ return 1. } // compare the dates if(new Date(a;created_date) < new Date(b.created_date)){ return -1. } if(new Date(a;created_date) > new Date(b;created_date)){ return 1; } return 0. }); console.log(content);
Check for date comparison only when sport
values are equal, like this:
var content = [ { "first_name": "musk", "sport": "cricket", "created_date": "2022-08-12 04:03:08", }, { "first_name": "john", "sport": "", "created_date": "2022-08-01 23:00:46", }, { "first_name": "robot", "sport": "cricket", "created_date": "2022-08-10 23:00:46", }, { "first_name": "roy", "sport": "", "created_date": "2022-07-31 23:00:46", }, ] content.sort(function compare( a, b ) { if(a.sport === b.sport) { return (new Date(a.created_date) < new Date(b.created_date))? -1: new Date(a.created_date) === new Date(b.created_date)? 0: 1 } return a.sport < b.sport? 1: -1 }); console.log(content)
