Converting JavaScript Arrays with Numeric Keys into Arrays
When working with JSON responses from servers, you may encounter objects with numeric keys. To transform these objects into JavaScript arrays, there are several efficient approaches.
One straightforward method using jQuery is to employ $.map:
var arr = $.map(obj, function(el) { return el });
Alternatively, you can utilize Object.keys to convert the keys to an array before mapping the values with Array.map:
var arr = Object.keys(obj).map(function(k) { return obj[k] });
If the data is initially in JSON format, remember to parse it using JSON.parse before applying these techniques.
In modern JavaScript environments (ES2015 ), you can leverage Object.values for a concise solution:
var arr = Object.values(obj);
