Problem is it'll return "1 seconds ago". Here's my modified version:
const MINUTE = 60;
const HOUR = MINUTE * 60;
const DAY = HOUR * 24;
const WEEK = DAY * 7;
const MONTH = DAY * 30;
const YEAR = DAY * 365;
function getTimeAgo(date) {
const secondsAgo = Math.round((Date.now() - Number(date)) / 1000);
if (secondsAgo < MINUTE) {
return secondsAgo + ` second${secondsAgo !== 1 ? "s" : ""} ago`;
}
let divisor;
let unit = "";
if (secondsAgo < HOUR) {
[divisor, unit] = [MINUTE, "minute"];
} else if (secondsAgo < DAY) {
[divisor, unit] = [HOUR, "hour"];
} else if (secondsAgo < WEEK) {
[divisor, unit] = [DAY, "day"];
} else if (secondsAgo < MONTH) {
[divisor, unit] = [WEEK, "week"];
} else if (secondsAgo < YEAR) {
[divisor, unit] = [MONTH, "month"];
} else {
[divisor, unit] = [YEAR, "year"];
}
const count = Math.floor(secondsAgo / divisor);
return `${count} ${unit}${count > 1 ? "s" : ""} ago`;

Just what I needed @rex, thanks! Tiny fix: You are missing const on the count.
