在「A guide to setting up Vim for JavaScript development」這邊看到可以用 sheerun/vim-polyglot 吃多種語言：
Vim supports basic syntax highlighting for JavaScript but I found it suboptimal especially when it comes to modern ES2015+ syntax, and it doesn’t support JSX when working with React. I found that vim-javascript and vim-jsx solved my problems in both instances.
However, I later replaced those two with vim-polyglot which is a plugin that bundles several other syntax plugins for over 100 languages, and loads them on demand so that performance is not affected.
先前遇到新的語言就得去找新的 plugin 加，現在看起來可以用一套吃遍天下 (只要一直更新)，換過去後先短暫的測了一下，沒什麼大問題...
