javascript is one of the famous langugae,it's needs a built-in driver. As it
was not present in the userdiff & this leads to the patch.
first line consists of some of the well used javascript
keywords.statements in js use one or many keywords like variable declaration,
function definition, logical opreation etc.The following line is for statements
of type object.method() & it is expected to end any statement using ";". The
word_regex in js is usual alpha-numeric.last two line shows all the different
types of opreators in js and different types of number system used in js are
also defined.

I'm working on "Add more built-in driver for userdiff" as my microproject for
Gsoc17. This patch is for javascript which is one of the popular language at
this time. I'm willing to add more driver for other laguage that isn't present
in userdiff.c and again I'm willing to participate in Gsoc17 with git. I'm
eager to know about this patch.
thanks & regards
