tl;dr The inode is a 64-bit integer which the high-level JS language doesn't have.

They could (1) make a two element UInt32Array or (2) use strings or (3) use all 64 bits of the floating point JS number type.

It's worth pointing out that (3) sounds good, but it's an imperfect solution too. If Number.isNaN(num) is true, num === num will be false. Not just one, but several 64-bit patterns are considered NaN when represented as a floating-point number, so if all possible 64-bit values can be used, this could cause the opposite problem where inodes that are actually the same are considered not equal by JavaScript.
