When working with Svelte, the #each construct allows for easy iteration over array-like objects. But what if you have a JSON dictionary object instead? Is there a way in Svelte to iterate over this type of object in order to populate a dropdown menu? The data I am dealing with is the result of an API call and has the following structure:
const obj = { foo: "bar", batz: "boink" }
To begin, transform your object into an array that contains the desired information, whether it be keys, values, or both.
Once you have created this array, you can easily iterate through it using an #each loop. Check out this REPL for a practical example.
<script>
const obj = { foo: "bar", batz: "boink" }
let keys = Object.keys(obj) // ["foo", "batz"]
let values = Object.values(obj) // ["bar", "boink"]
let entries = Object.entries(obj) // [["foo", "bar"], ["batz", "boink"]]
</script>
{#each entries as [key, value]}
<div>
{key} - {value}
</div>
{/each}
