Please help me to solve these TS2304: Cannot find name 'Promise' errors

Answer

You just need to change your target to es6 inside your tsconfig.json to resolve this issue.

{
  "version":"2.13.0",
  "compilerOptions": {
    "target": "es6", //<- change here
    ......
  },
  "exclude": [
        "node_modules"
    ]
}

Other way what you can do is, you need to make sure you have es6-shim.js have been referred there on page and then follow this answer that would not need to change target option.
