Script Preparation code:

const strs = [
  "tag:cool",
  "a8798d75-18ed-473b-a28b-0b756dd99151",

Tests:

split

function doSplit(str) {
  const parts = str.split(':')
  if (parts.length !== 2) {
    return null
  }
  
  return parts[0]
}

for (const str of strs) {
  doSplit(str)
}

​x
 
function doSplit(str) {  const parts = str.split(':')  if (parts.length !== 2) {    return null  }    return parts[0]}​for (const str of strs) {  doSplit(str)}

rgx

const rgx = /(?<tag>[a-z]+):(.*)?/
function doRgx(str) {
  const res = str.match(rgx)
  if (!res) {
    return null
  }

  return res.groups?.tag ?? null
}

for (const str of strs) {
  doRgx(str)
}

 
const rgx = /(?<tag>[a-z]+):(.*)?/function doRgx(str) {  const res = str.match(rgx)  if (!res) {    return null  }​  return res.groups?.tag ?? null}​for (const str of strs) {  doRgx(str)}
