Nope. In Rust, a semicolon denotes a statement while a lack of semicolon is an expression so you can't just omit them at will. This does lead to cool things though like if/else blocks being able to produce values if they end in an expression. But the expression type is checked so you're less likely to make a mistake. You can see an example here: https://doc.rust-lang.org/rust-by-example/flow_control/if_else.html

In JavaScript I never skip semicolons because I've seen those subtle bugs.
