Question

including a collection of values into a JSON data structure

Currently, I am iterating through some JSON data (grouped tweets from Twitter) to tally the frequency of specific keywords (hashtags) in order to generate an organized list of common terms.
this (19)
that (9)
hat (3)

I have achieved this by initializing

var hashtags = [];

The process involves assigning a value of 1 for each new word encountered for the first time:

hashtags[new_tag] = 1;

For subsequent occurrences of the same word, I simply increment the count:

hashtags[hashtag]+=1;

This approach results in a straightforward data structure with words and their respective frequencies. To extract the necessary information, I utilize:

$.each(hashtags, function(i, val){
    console.log(i+ " - "+ val);
})

Upon reflection, I realize it would be beneficial to also pinpoint the clusters in which these words are located. Therefore, I believe I should incorporate a list (array) within my "hashtags" object.

Essentially, I aim to construct a JSON format resembling:

hashtags: {"this": 19, clusters: [1,3,8]}, {"that": 9, clusters: [1,2]}

How can I seamlessly integrate arrays into the hashtags object?

To start, create a container to store all the hashtags:

var hashtagsContainer = {};

If a hashtag is new and hasn't been encountered before, initialize it in the container:

hashtagsContainer[newTag] = {
    count: 0,
    clusters: []
};

Increase the count for the hashtag:

hashtagsContainer[newTag].count += 1;

Include the cluster information for the hashtag:

hashtagsContainer[newTag].clusters.push(theCluster);

To achieve the desired outcome, you should utilize an Object ({ }) for storing hashtags because strings are being used as keys. Using an Array ([ ]) would be more suitable if indexes were being used as keys. Here is a suggested structure:

var hashtags = {
    "this": { count: 19, clusters: [1, 3, 8] },
    "that": { count: 9, clusters: [1, 2] }
};

When adding a new hash tag, follow this format:

hashtags[new_tag] = { count: 1, clusters: [cluster] },

For incrementing a hash tag, use the following approach:

hashtags[hashtag].count++;
hashtags[hashtag].clusters.push(cluster);
