Hi there! I got some questions concerning step 7 from Part 4 of the Ravenous proyect.
- What is a Polyfill?
- How does whatwq-fetch work?
also, when runing
npm install whatwg-fetch --save this message appears to me:
"npm WARN firstname.lastname@example.org requires a peer of typescript@* but none is installed. You must install peer dependencies yourself.
updated 1 package and audited 36241 packages in 34.032s
found 78 vulnerabilities (63 low, 15 high)
npm audit fixto fix them, or
npm auditfor details"
I installed Typescript, don’t know what peer dependencies are. I very much appreciate some orientation.
