This is my Code:

function NewPerson() {
    var count = parseInt($('#HiddenField').html());
    count++;
    $('#HiddenField').html(count);
    Var dynamicVariable = 'Person'+'Count' 
}

I want to define variable on this line Var **dynamicVariable** = 'Person'+'Count'

Now I need to create variable with count number

• Are you trying to append the variable count? Then, use this var dynamicVariable = 'Person' + count; – Eddie Commented Dec 5, 2017 at 6:42

You could also try this.

  var count = 1; //Let this be your count variable.
  var PersonString = "Person" + count; //Building a dynamic name for your variable
  alert(PersonString); //Person1 will be alerted
  window[PersonString] = "One";
  alert(Person1); //One will be alerted.

P.S : Here variables created dynamically will have a global scope.

Usually, the design pattern in this scenario is to use an object.

//These are your variables
var myVar1 = '1';
var myVar2 = '2';

//The object holding all your dynamic variables
var MyVarObj = {};


//Create dynamic variables (object properties)
MyVarObj[myVar1] = 'value1'
MyVarObj[myVar2] = 'value2'


console.log(MyVarObj);   // {1: 'value1', 2: 'value2'}
