When you create a setInterval once, it will automatically call function (first argument) every 1000 milliseconds (second argument). So you don't need to do it inside while, just put incrementing of i inside the function (first argument).

function counter() {
  var i = 0;
  // This block will be executed 100 times.
  setInterval(function() {
    if (i == 100) clearInterval(this);
    else console.log('Currently at ' + (i++));
  }, 1000);
} // End

counter()

setInterval

Update 1

function counter() {
    var i = 0;
    var funcNameHere = function(){
        if (i == 100) clearInterval(this);
        else console.log( 'Currently at ' + (i++) );
    };
    // This block will be executed 100 times.
    setInterval(funcNameHere, 7000);
    funcNameHere();
} // End
