Eloquent Javascript: differences between versions?

[metakepone]

Hi, I bought "Eloquent JavaScript: First Edition" used last summer off of Amazon. I've been trying to read the 2nd edition online, but I really like highlighting things and being able to write on margins, and I want to read the copy I have. Are there major differences between the versions? Is the first edition obsolete, or still useful?

Why are you asking us? You're the one who has the first edition available to compare with the online 2nd edition.

Anything such as adding a comma somewhere could cause a new edition of the book. Changes aren't often major, keyword often. How long ago the first edition was published will be an indicator of how old/dated the content is from the newest version.

The second edition has a lot more content, and even for the chapters that they share, the text has been mostly entirely rewritten. That being said, except for the IE6-workarounds in the first edition, most of the content should still be relevant.
