Hello, I am new to this and still learning the new stuff :)

I have a question about mine javascript and i hope this is the right area to get a answer :)

So i made a code that every 2e of 3e word change from color(its a bit random). I used 'getElementById' but i know so far mine knowledge goes that it only works for 1 id. And i want to use the code on more places with diffrent "id's" but don't want to duplicate mine code.

Could some on explain to me what to do? Or is there documentation i could read with some explanation how to make maybe a function with the code? I hope some on could explain how to clean this up ;)

Here is mine code:

var paragrapgh = document.getElementById("ads_colordtitel");
var words = paragrapgh.innerText.split(" ");
var colors = ["#0B88EE", "#FFFFFF"];
var spans = [];

for(var x = 0; x < words.length; x++){
var color = colors[Math.floor(Math.random()*colors.length)]
var span = "" + words[x] + ""

spans.push(span);

}

paragrapgh.innerHTML = spans.join(" ");
