I decided that I, finally, can't avoid learning a bit about JavaScript, and hence got myself a copy of The O'Reilly Book -- this time, JavaScript. The Definitive Guide.. The book -- at 916 pages and 1.3kg, and it's a paperback! -- begins with the words:
JavaScript is a lightweight, interpreted programming language
Makes me long for the times of Kernighan and Ritchie -- 272 pages, and 650g, in the bound version.
Seems like the definition of "lighweight" has changed quite a bit.
