I would like to understand this terminology "byte-for-byte" in this phrase:

Byte-for-byte, JavaScript is still the most expensive resource we send to mobile phones, because it can delay interactivity in large ways.

This terminolgoy appears in this article The Cost Of JavaScript In 2018

  • sounds like a takeoff on "pound for pound" from Boxing rankings...if you were to make a ranking of content-types [sent to a mobile device] by bytes transferred, JavaScript content would rank highly. – Corey Goldberg Aug 26 '18 at 07:07

IMO it means a trade-off, an exchange of goods or services, in which one transfer is contingent upon the other. Like: eye for an eye or quid pro quo,.. but in technology manner.

Because Js not really optimized for mobile phones about the sizes.
