bug: huge console.log will crash the browser

[jimniels]

Open a blank file and enter this code for a javascript cell

let res = await fetch("https://github.com/LeoDog896/npm-rank/releases/download/latest/raw.json");
let data = await res.json()

console.log(data)

Then go to the console tab and try viewing the output. It slows down the page tremendously and, in some cases, makes me end up on the "Aw snap" page of chrome (cause the tab crashed).

We should probably do something to protect against logging too much in the console. Something where we just trim it off and like 10,000 lines and just say "500,000 more lines" or something

Alternatively, we can window the console so this works.
