TS2304: Cannot find name ‘Map’.
TS2304: Cannot find name ‘Set’.
TS2304: Cannot find name ‘Promise’.
TS2304: Cannot find name ‘MapConstructor’.
TS2304: Cannot find name ‘SetConstructor’.
switch the transpiler’s target from ES5 to ES6. To do that, change your tsconfig.json
{
  “compilerOptions”: {
    “target”: “es6”,
    “module”: “system”,
    “moduleResolution”: “node”,
     ...
  },
“exclude”: [
    “node_modules”,
    ...
  ]
}
