Sometimes, we want to iterate over a JavaScript associative array in sorted order.
In this article, we’ll look at how to iterate over a JavaScript associative array in sorted order.
How to iterate over a JavaScript associative array in sorted order?
To iterate over a JavaScript associative array in sorted order, we can get the keys of the object with Object.keys as an array.
Then we call the sort method on the array.
For instance, we write
const sortedKeys = Object.keys(a).sort();
to get the keys of object a as an array with Object.keys.
Then we call sort to return an array that sort the array of keys alphabetically.
Conclusion
To iterate over a JavaScript associative array in sorted order, we can get the keys of the object with Object.keys as an array.
