Format Reading Time with JavaScript

Reading time is a pretty common functionality in blogs.

The formatReadingTime() function below displays cups of coffee as indicators of the minutes it takes to read the post.

1function formatReadingTime(timeToRead) {
2  const minutes = `${timeToRead > 1 ? `minutes` : `minute`}`;
3  const cups = Math.round(timeToRead / 5);
4
5  return `${new Array(cups || 1)
6    .fill('☕️')
7    .join('')} ${timeToRead} ${minutes} read`;
8}
