Vì sao dùng công cụ này

• One tool covers three syntactically similar block-end-keyword languages.
• Per-language openers: <code class="rounded bg-slate-100 px-1 text-xs dark:bg-slate-800">do/end</code> for Ruby, <code class="rounded bg-slate-100 px-1 text-xs dark:bg-slate-800">function/end</code> for Lua, braces for Perl.
• Pure client-side — your code never leaves the browser.
• For canonical output use RuboCop (Ruby), StyLua (Lua), or perltidy (Perl) locally.
