Maybe you should read the ECMA Script specs before you post a list. Some of these words are not reserved words at all. Some, like "transient" are not even a term used in the language, must less a reserved word. A saw a word that only becomes reserved when "use strict" is turned on, but the others in the "use strict" keyword list are not here. There are only 38 JavaScript "reserved words" and NOT 64. And there are an additional 8 words when "use strict" is used. But combined that is only 46 which is still far less than the 64 he posts here.
