Why do we use &amp?

& is the code behind the symbol & (an ampersand) . There are many of these HTML codes beginning with & and ending with ; that represent special characters that could not otherwise be displayed on a web page.

So AMP stands for Accelerated Mobile Pages , NOT Accelerated Mobile Apps.

Start of a character reference & is HTML for “Start of a character reference”. & is the character reference for “An ampersand”. If you used a character reference for a real character (e.g. ™ ) then it would appear in the URL instead of the string you wanted.

I am assuming you already have a React app and you are happy. You can opt-in to AMP on a page-by-page basis , and that’s exactly what you should do. Most importantly, make sure to measure exactly how AMP performs while stepping into the waters slowly.22 Eki 2019
