Cannot find module 'esri/Map' in JS from TypeScript

[ShanmugapriyaL]

I have been trying to start working on the custom widget using TypeScript. So I have followed the example from here. 

Import statement in main.ts file.

I was facing the import statement problem.

Solved the above issue by changing the export option in index.d.ts

My tsconfig.json file,

After compiling the ts file, I am trying to recover the issue in main.js file,

My main.js file,

Getting an error while compiling js file,

Browser window:

The "Esri/Map" module is cannot be founded in the JS file. If I am missing anything on this above code, kindly comment to solve this issue.

Thank you in advance.
