Word Density Counter In Vanilla JavaScript – density.js

density.js is a pure JavaScript library that can be used to count and calculate how many times your words appear in the HTML/Text.

How to use it:

1. Download and import the density.js into the HTML file.

<script src="density.js"></script>

2. Define the text in which you want to count the word density.

const html = `<h1>A html heading</h1>
<p>Here is a html paragraph</p>`;

3. Output the results.

// Simple sorted
results = density.getSorted(html);
console.log(results);
// Simple unsorted
results = density.getUnsorted(html);
console.log(results);

// results in
0: {count: 2, word: "a"}
1: {count: 2, word: "html"}
2: {count: 1, word: "heading"}
3: {count: 1, word: "here"}
4: {count: 1, word: "is"}
5: {count: 1, word: "paragraph"}

4. Specify an array of stop words to ignore.

results = density.getSorted(html, {
  stopwords: ["here is"]
});
console.log(results);

5. With selected words.

results = density.getSorted(html, {
  selected: ['html heading', 'a', 'paragraphen']
});
console.log(results);

6. Specify the number of words on each row. Default: 1.

results = density.getSorted(html, {
  words: 2
});
console.log(results);

7. Specify the minimum number of characters. Default: 0 (disable).

results = density.getSorted(html, {
  characters: 2
});
console.log(results);
