I often read complaints about how hard it is to learn Elisp and that therefore we should rewrite Emacs in Javascript or something equally silly. The fact is, of course, that Elisp, like most Lisps, is actually easy to learn and once you\u2019ve spend a bit of time with it, you\u2019ve got a very powerful tool for solving text manipulation problems or, really, just about any problem at all.<\/p>\n
