Before, this was conditional to the directory's existence. Add it
anyway, in case the folder is created while the buffer is open.
This may cause a problem is the project root changes while the buffer is
open, but for that case there's M-x doom/reload-project.
+ No need for some rjsx-mode hooks, when it is derived from js2-mode
(thus, js2-mode hooks will run in rjsx-mode).
+ Reorganized package configs with major modes at the top.
+ Fix incorrect usage of add-hook! with three arguments for rjsx-mode.
+ enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster
startup; ~5-20% general boost
+ reduce consing, function calls & garbage collection by preferring
cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and
various cl-lib filter/map/reduce functions) -- where possible
+ prefer functions with dedicated opcodes, like assq (see byte-defop's
in bytecomp.el for more)
+ prefer pcase & cond (faster) over cl-case
+ general refactor for code readability
+ ensure naming & style conventions are adhered to
+ appease byte-compiler by marking unused variables with underscore
+ defer minor mode activation to after-init, emacs-startup or
window-setup hooks; a customization opportunity for users + ensures
custom functionality won't interfere with startup.
