Use the split method of the string object to convert the user's entry into an array. If there is more than one task in the entry, use the concat method of the tasks array to add the new tasks to the tasks array. This is what I have been working with.

"use strict";
var $ = function(id) { return document.getElementById(id); };

var tasks = [];

var displayTaskList = function() {
    var list = "";
    // if there are no tasks in tasks array, check storage
    if (tasks.length === 0) {
        // get tasks from storage or empty string if nothing in storage
        var storage = localStorage.getItem("tasks") || "";

        // if not empty, convert to array and store in global tasks variable
        if (storage.length > 0) { tasks = storage.split("|"); }
    }
   
    // if there are tasks in array, sort and create tasks string
    if (tasks.length > 0) {
        tasks.sort();
        list = tasks.join("\n");
    }
    // display tasks string and set focus on task text box
    $("task_list").value = list;
    $("task").focus();
};

var addToTaskList = function() {  
    var task = $("task");
    if (task.value === "") {
        alert("Please enter a task.");
    } else {
        // add tasks to array and local storage
        var newTasks = tasks.split(",");
  var nameTasks = newTasks.concat(",");
  alert (nameTasks.length);
  alert (nameTasks);

        // clear task text box and re-display tasks
        task.value = "";
        displayTaskList();
    }
};

var clearTaskList = function() {
    tasks.length = 0;
    localStorage.tasks = "";
    $("task_list").value = "";
    $("task").focus();
};

window.onload = function() {
    $("add_task").onclick = addToTaskList;
    $("clear_tasks").onclick = clearTaskList;   
    displayTaskList();
};

<html>

<body>

<button onclick="splitInputstring ()">Try it</button>

<script type="text/javascript">

window.entry = prompt("Enter the entry");// Create a Prompt box for input number of entry

function splitInputstring (){ // split function

window.Splitstr; // global variable

var tr=[]; // variable declaration

if(entry==1){ // condetion for entry==1

var Str = prompt("Enter the string"); // Create a Prompt box for input string

Splitstr = Str.split(""); // Split the string

for(i = 0; i < Splitstr.length; i++)

{

document.write("<br /> Element " + i + " of the array is: " + Splitstr[i]);

}

}

if(entry>1){ // condetion for entry>1

for(i = 0; i < entry; i++){

var Str1=[]; // variable declaration

tr[i] = prompt("Enter the string"); // Create a Prompt box for take multiple string as input

alert(tr[i]); // print input string in alert box

Str1 =Str1+tr[i]; // concatenat the multiple string

document.write(Str1); // print concatenat string

}

}

}

</script>

</body>

</html>

Note- when you run this code first one prompt box will come for ask number entry.Then one "Try It" button will come, you just click it for taking input string.Again prompet will come for the input string.If entry ==1 then input string will split.If entry >1 then prompt will come for input string and the alert box will print input string.For entry>1 case result will print only concatenate a string.
