Read array values in a loop in JavaScript

Question

I have an array in JavaScript that have defined these values:

var myStringArray = [\"1\",\"2\",\"3\",\"4\",\"5\",\"6\",\"7\",\"8\",\"9\",\"10\"];

Answer 1

Your variable i is local to the for loop which means it basically resets every time the loop is started. So first make your variable i global.

var i=0;
function employeeNames(){
    var empList =  ["1","2","3","4","5","6","7","8","9","10"];
    var output = [];
    var j=0;
    while(j<3)
    {
        output.push(empList[i])
        i=(i+1)%empList.length;
        j++;
    }
    return output;
}

console.log(employeeNames());
console.log(employeeNames());
console.log(employeeNames());
console.log(employeeNames());
console.log(employeeNames());
