>printing of a hundred thousand character minified line of JavaScript. Yeah... Terminal is not the issue, rather why you have 100000 line js file in the first

    Yes? Why do you need 100000 characters of JS? Maybe de-bloat your shit. Also grepping through that is even easier than 100_000 lines (which I assumed you meant since grepping over one line of 1_000_000 characters takes so little time that is not any kind of argument)

      It's not the grepping that takes the time, it's the printing the highlighted output to the terminal. Keep up.

  This really started to bother me. How does terminal emulator speed up grepping a large file? I made a random file with 100 000 lines and using 3 different terminals (Default Terminal, iTerm2, and Kitty) and using two different grep tools (grep and rip-grep) with and without tmux I can not see any meaningful performance difference. Do I just not understand what terminal emulators do? How does choice of text printing matter when you run a script? I could see a tiny performance improvement with kitty when I ran just cat on the file in a loop, but the difference was so tiny that if you want to argue that this is the performance benefit worth using kitty for I have bad news for you since the worst case with kitty was then noticeably worse than in competition.
