There are interviews to Eich and Zawinski in the "Coders at Work" book that tell a lot about the context were Javascript was developed. They are very interesting, and that book is almost obligatory read to anyone interested in the history and current state of sofware development. Crockford is also interviewed there and asked about language subsetting and the thinking behind Javascript: The Good Parts.
