I have a funny story I need to tell some day about how I could get a 4GB JSON loaded purely in the browser at some insane speed, by reading the bytes, identifying the "\n" then making a lookup table. It started low stakes but ended up becoming a multi-million internal project (in man-hours) that virtually everyone on the company used. It's the kind of project that if started "big" from the beginning, I'd bet anything it wouldn't have gotten so far.

Edit: I did try JSON.parse() first, which I expected to fail and it did fail BUT it's important that you try anyway.
