- Refactoring is a breeze due to the strict typing and compiled aspect
- The compiler is very helpful to work with most of the time and helps point you in the right direction for the most part
- Immutability and Uni-directional data flow is baked right in — think Redux
- Functional design and currying make functional composition very nice to work with
- Styling system based on modern CSS in JS approaches (see Styled-Components)
- You mostly don’t need to write front end tests!
