Code problem

const stringCheck = (strBig, strSmall) => {
  let count = 0
  const bigStrLen = strBig.length
  const smallStrLen = strSmall.length
  let tempString = ""


  for(let i=0; i<bigStrLen - smallStrLen + 1; i++ ) {
    if (strBig[i] === strSmall[0]) {
      tempString = strBig.slice(i, i + strSmall.length)
        if (tempString === strSmall) {
          count += 1
          tempString = ""
        } else {
          tempString = ""
        }
    }
    // console.log(strBig.slice(i, i + strSmall.length))

    }
  return count

}


console.log(stringCheck("hello world", "or")) // <= 1
console.log(stringCheck("momomomomomomomomomo", "mo")) // <= 10
console.log(stringCheck("hello world", "mo")) // <= 0
