npm unable to start - getting TS2304 error
One fine day, i tried to start my project with npm start and bump into this error :-
node_modules/@angular/common/src/directives/ng_class.d.ts(46,34): error TS2304: Cannot find name 'Set'.
Yes it is a typing error and just issue the following command to fix it.
npm install --save-dev @types/core-js
Try npm start again.
