Offset is difference from a starting point or a previous position

“Offset” is not enough on its own. Offset from what? Start of file? Absolute offset. Previous offset? Relative offset.

2nd order offset. The offset from the

This is crucial: instead of encoding large column numbers like 27698 in minified files, source maps only store small deltas like +7 or +15, making the encoded strings much more compact. Wouldn't "offset" be a more apt term?

Delta and offset mean the same thing — the difference between two amounts.

Delta is perhaps slightly more obscure outside of a math setting. Perhaps.

I feel like choosing the synonym that happens to be one letter shorter when the operation is literally intended to track things in a way that's more conscise is about as "apt" as it could be!
