How to push JSON object into an array using JavaScript?

Answer: If there is a single object and you want to push the whole object into an array then you do simply push the object.

var feed = {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"}; var data = []; data.push(feed); console.log(data);

If you have multiple objects then do iterate the object.

var my_json = {created_at: "2017-03-14T01:00:32Z", entry_id: 33358, field1: "4", field2: "4", field3: "0"}; var data = []; for(var i in my_json) { data.push(my_json[i]); } console.log(data);
