indexof is not a good way

var fs = require("fs");
var data = fs.readFileSync('/System/Volumes/Data/home/2544842260/Public/100again.txt');
var arr = data.toString().split("\n");
//arr.pop();
arr.sort();
var tmp = arr;

var wordcounter = [];
var wordlist=[]
var savelist=[]



//words counting
var wordcountertmp=[]
var wordlisttmp=[]
for (var s = 0; s < tmp.length; s ++ ){
    posiOf1stSemicolon=tmp[s].indexOf(";");
    var wordtmp = tmp[s].slice(0,posiOf1stSemicolon)
    //check if it is a new word. yes - add the new word. no - plus 1
    var existchecker = wordlisttmp.indexOf(wordtmp)
    if(existchecker==-1){
        wordlisttmp.push(wordtmp)
        wordcountertmp.push(1)
    }
    else{
        var posi=existchecker;
        wordcountertmp[posi]=wordcountertmp[posi]+1
    }
    //get the most counted word
    var maxTmp=0
    for (i=0;i<wordcountertmp.length;i++){
        if (maxTmp<wordcountertmp[i]){
            maxTmp=wordcountertmp[i]
            indexOfMostCountedWordtmp=i
        }
    }
    var mostCountedWordtmp=wordlisttmp[indexOfMostCountedWordtmp]
}
//save the less counted species, and remove saved/counted item from tmp
for(var s = 0; s < tmp.length; s ++){
    if (tmp[s].indexOf(mostCountedWordtmp) == -1){
        console.log("看这里！")
        console.log(tmp[s])
        savelist.push(tmp[s])
        tmp.splice(s,1)
    }
    else{
        tmp[s]=tmp[s].slice(mostCountedWordtmp.length+1)
    }
}
wordcounter.push(wordcountertmp)
wordlist.push(wordlisttmp)

so! with associate array

var fs = require("fs");
var data = fs.readFileSync('/System/Volumes/Data/home/2544842260/Public/100again.txt');
var arr = data.toString().split("\n");
arr.sort();
var speciesNumber=arr.length
var speciesList={}
var processlist=speciesList
var savelist=[]

var wordList=[]
var countList=[]

//save the data to array
for (var s=0; s<speciesNumber; s++) {
    var rowKey=s+1
    processlist["species"+rowKey]=arr[s].split(";")
}

//counting words
var layer=0
do{
    var counttmp=[]
    var wordListtmp=[]
    for (var s=0; s<speciesNumber; s++){
        var rowKey=s+1
        var existchecker="nonexist"
        for (i=0;i<wordListtmp.length;i++){
            console.log("s "+s)
            console.log("rowkey "+rowKey)
            console.log("remain "+countNumber)
            console.log("species "+rowKey)
            console.log("layer "+layer)
            if (processlist["species"+rowKey][layer]===wordListtmp[i]){
                existchecker="exist"
                var posilog=i
            }
        }
        if (existchecker=="exist"){
            counttmp[posilog]=counttmp[posilog]+1
        }
        else{
            wordListtmp.push(processlist["species"+rowKey][layer])
            counttmp.push(1)
        }
    }
    //get most counted word
    var countNumber=0
    for (var j=0;j<wordListtmp.length;j++){
        if (countNumber<counttmp[j]){
            countNumber=counttmp[j]
            var indexOfCountNumber=j
        }
        var mostCountedWord=wordListtmp[indexOfCountNumber]
    }
    //keep the most counted species in processlist;
    //save other to savelist.
    savelisttmp=[]
    for (var s=0; s<speciesNumber; s++){
        var rowKey=s+1
        if (mostCountedWord!==processlist["species"+rowKey][layer]){
            savelisttmp.push("species"+rowKey)
            delete processlist["species"+rowKey]
        }
    }
    if (savelisttmp.length!==0){
        savelist.push(savelisttmp)
    }

    
    
    //save less counted words and numbers to list
    wordList.push(wordListtmp)
    countList.push(counttmp) 
    layer=layer+1
    speciesNumber=countNumber



    console.log("processlist length:")
    console.log(Object.keys(processlist).length)
    console.log("wordlist:")
    console.log(wordList)
    console.log("countlist:")
    console.log(countList)
    console.log("times:")
    console.log(countNumber)
    console.log("most counted word:")
    console.log(mostCountedWord)
    console.log("   ")
    console.log("savelist:")
    console.log(savelist)
    console.log("   ")  
}
while (countNumber>(speciesNumber/8))

but the loop program is not going well
