Can't help but call out Rust here for it's (imo excellent) syntax.

if condition {do_x()} else {do_y()}

Basically there's no need for line breaks between if/else, but also they decided not to add a ternary conditional operator.

  if (condition) { do_x() } else { do_y() }

That's the JavaScript version of what you wrote, and it's nearly identical. JavaScript doesn't require line breaks.

The significant difference is that in Rust, like in Lisp, `if` is an expression, so if-else essentially is the ternary operator.

    const x = cond1 ? a 
            : cond2 ? b
            : c

becomes in Rust

    let x = if cond1 { a }
            else if cond2 { b }
            else { c }
