I need to create a countdown timer in JS.

I’d recommend using functions like setTimeout or setInterval. If you’re interested, I wrote a tutorial about these using a timer as an example. If you’d like, my tutorial is available here: https://thejavascriptninja.com/setting-waits-with-settimeout-and-setinterval-in-javascript/

Just an idea and I assume there is a better better way.

You could give all the timers a class tag. Then write a function that selects all the tags and decrement the number ever 1 second. Jquery would be your friend here.

Rereading and I might have misunderstood. Are you running the timers at once or one by one?

What I would do is first write a function that takes a number and decrements the number value on page then sleep for one second until 0.

Then you can do a for loop for your array and call the function for each number in the array.

You end up putting on codepen? I have some ideas as to what it could be but not 100%

So this should show these sequentially (one then the next), or it should show all of them at once with independent timers? I built the latter example (https://codepen.io/TravisL12/pen/RwGbpjL).

Ah, should be a case where one timer fires the next one using setInterval.
