javascript - Accessing Json file in streaming mode -

I have a 50 MB-sized JSON file that I'm calling with PHP and it takes ages to load it. is.

If so, this is like the 2nd arrays in JSN:

<[x, y, z], [x, y, z], ...] , [X, y, z], [x, y, z], ...]

How to call 50 2D ARADs every time?

Also tell me in a more efficient way than using JSN here. I am using a WebSpending JS script to gather data from websites and save them in the Jason file.
