To be pedantic, Javascript isn't a scripting language; it is the 
combination of one (Ecmascript) and various browser and document models. 
Strictly speaking it refers to those models as in early versions of 
scriptable Netscape browsers, although it is now used for any 
combination of Ecmascript and such object models. It is not a 
technically precise term.

It is, in fact, the object models that are the difficult bit and prevent 
the common text only browsers and netsurf implementing "javascript". 
The netsurf road plan for javascript also mentions the need for internal 
structures that support efficient dynamic modification of the document 
and its style sheets (many javascripted sites need a lot of processing 
power - it can now take 30 seconds to a minute to get a page up on my 
old, 350MHz, machine).
