The function displays more visible logs in console (cleared by default), make table of arrays and group elements when a string is passed in isMapped argument. See example below, in comments.

log.js

export const log = (obj, clear = true, mapKey) => {
  const title = "font-size: 19px; color: #e65264"

  if (clear) {
    console.clear()
  }

  if (mapKey) {
    console.group(mapKey)
    obj.map(o => console.log(o))
    console.groupEnd(mapKey)
  } else if (Array.isArray(obj)) {
    console.log("%c Array 👇️", title)
    console.table(obj)
  } else if (typeof obj === "string") {
    console.log("%c String 👇️", title)
    console.log(`%c ${obj}`, "font-size: 14px; color: yellow")
  } else {
    console.log("%c Object 👇️", title)
    console.log(obj)
  }
}

log(smth)

log(arr)

    arr.forEach((el, i) => {

      log([el.obj, el.arr, el.str], false, `arr index-${i}`)

    })

Do not forget to provide false to clear argument for displaying all iterations
