Ionic start warnings - how to update dependencies versions

I am new to ionic. Created from apps in ionic 3 then switching to ionic 4. while creating new project (ionic start), i am getting warning “npm WARN deprecated” regarding dependencies version. To avoid this, i uninstalled all then install node, cordova, ionic, clear cache. Still having this warning.
I am curious to know from where the npm is getting these versions. Is there anything i can do to avoid these error.
