CSS -> Stylus. I don't even have to type brackets and colons and not just semi colons.
JS -> JS (TS). Some people may not be aware but you can fully write JS by omitting semi colons. (Except on a few occasions* but I can write a project without one just fine and decent editor will warn you when you're supposed to have one, like IntelliJ and derivatives. Configure it to not prefer semi colons and 1 shortcut key to reformat the code and all stripped.)
PHP -> Ruby, Python, JS all don't ask you for semi colons. Array expression is also too verbose in PHP.
Java -> Kotlin.
HTML -> Pug/Slim/Etc. While there's no semi colon, the verbosity of HTML is insane, people will appreciate the simplicity of template engines like Pug and never look back.
Bash -> Bash. They didn't have one decades ago...
