this is my html file code and here my component.ts file code :-

  $("#phone").intlTelInput({
     utilsScript: "../../build/js/utils.js"
  });

 "core.es5.js:1084 ERROR Error: Uncaught (in promise): TypeError: $(...).intlTelInput is not a function"

You'll need to add the code below in your default-country-ip.js file.

$("#phone").intlTelInput({
  initialCountry: "auto",
  geoIpLookup: function(callback) {
    $.get('//ipinfo.io', function() {}, "jsonp").always(function(resp) {
      var countryCode = (resp && resp.country) ? resp.country : "";
      callback(countryCode);
    });
  },
  utilsScript: "js/utils.js" // just for formatting/placeholders etc
});


  var telInput = $("#phone"),
  errorMsg = $("#error-msg"),
  validMsg = $("#valid-msg");

// initialise plugin
telInput.intlTelInput({
  utilsScript: "js/utils.js"
});

var reset = function() {
  telInput.removeClass("error");
  errorMsg.addClass("hide");
  validMsg.addClass("hide");
};

// on blur: validate
telInput.blur(function() {
  reset();
  if ($.trim(telInput.val())) {
    if (telInput.intlTelInput("isValidNumber")) {
      validMsg.removeClass("hide");
    } else {
      telInput.addClass("error");
      errorMsg.removeClass("hide");
    }
  }
});

// on keyup / change flag: reset
telInput.on("keyup change", reset);
