Tutorial: Sorting ~1761 subreddits to see which subreddits are popular

Hi, I am researching of subreddits to make my next product. I want to get an overview of how I sort subreddits.

This will use vanilla JS.

1. grab the subreddits data from here https://pastebin.com/XVBDM4jn (copy the raw paste data)

Copy the json data to your html code like this (and don't forget to parse it)

<script>
let json_subreddits = JSON.parse(`//the copy pasted json data`)
</script>
Enter fullscreen mode Exit fullscreen mode

2. We need to sort the subreddits from most popular to least popular. We need to use sort() function.

But the problem is our data is an object, and not an array.
To convert it, we need to iterate the object

let json_subreddits = JSON.parse(`the copy pasted json data`);

let sortable = [];
for (let subreddits in json_subreddits) {
sortable.push([subreddits, json[subreddits]]);
}
Enter fullscreen mode Exit fullscreen mode

now we have an array

3. Use sort function

let json_subreddits = JSON.parse(`the copy pasted json data`);

let sortable = [];
for (let subreddits in json_subreddits) {
sortable.push([subreddits, json[subreddits]]);
}

sortable.sort(function(a, b) {
    return b[1] - a[1];
// this will return from big to small. to inverse it, just switch the a and b
// return a[1] - b[1];
});
Enter fullscreen mode Exit fullscreen mode

4. Console.log(sortable) to see the result

And you can view subreddits in your console. Enough to give you which subreddits are popular and which are least popular.
