What does the code inside the Math.random() function actually look like? How can I find that out?

Just curious if there is a place to see what the default JS functions actually look like... I'm curious how they are built to begin with.

Hi Ori,

It's hard to actually see the original source code for all browsers as it's part of the built-in JavaScript engine, however Chrome use their own in-house V8 engine which is open source so you can see all the behind the scenes stuff in one file.

Hi Ori,

Perhaps this Stackoverflow post can help point you in the right direction.
