[Suggestion] Frontend Performance Best Practices

[scottreed]

GZIP / Brotli compression is enabled. I would tweak the wording of this, where it says "Use a compression method such as Gzip or Brotli to reduce the size of your JavaScript files." I would suggest that it should be, enable compression methods such as Gzip and Brotli to to reduce the size of your requests (such as JavaScript, CSS and HTML). Favour Brotli over GZip where possible due to performance benefits of 14% smaller JavaScript files, 21% smaller HTML files and 17% smaller CSS files over Gzip. Also if using a CDN such as Cloudflare/Akami make sure that the CDN is setup to enable Brotli compression.
