If it's a bulky script, you could put it someplace out of the way (let's
say, name it ~/.vim/macros/foobar.vim ) then add several one-liners to
source it: e.g. either add

runtime macros/foobar.vim

either as part or all of each of
~/.vim/ftplugin/c.vim
~/.vim/ftplugin/cpp.vim
~/.vim/ftplugin/css.vim
~/.vim/ftplugin/javascript.vim

or else place in your vimrc the single autocommand (this is method 3 below)

autocmd FileType c,cpp,css,javascript runtime macros/foobar.vim

For both of these (which correspond to methods 2 above and 3 below) your
script will be sourced once for each editfile to which it applies: so it
should use :setlocal (not :set), :lcd (not :cd), :let b:var = value (not
:let var = value) etc.

One example of the latter would be, quite near the begin of your script:

if exists('b:did_run_foobar')
finish
endif
let b:did_run_foobar = 1

to avoid sourcing the script twice for the same buffer.
