Javascript: Unexpected token { - occurs when try to import custom class in typescript file into javascript file

I am writing simple CLI scripts for react-native project. But I am not available to import class from typescript to javascript. It throw me following error.

import { TestResult } from './src/lib/modules/test-result';
SyntaxError: Unexpected token {...

package.json

..."script": {..."formular:convert": "node convertor.js"...}...

convertor.js

import {TestResult} from './src/lib/models/test-result';...

test-result.ts

I stuggled to find the solution, and found some answers here and there, but all of them doesn't work.

Thanks for your help.
