Currently Rust is very slow to create some prototypes. Are there some IDEs with better support for creating Rust projects? Also some better intellisense would come handy.

Is Rust used in any of geospatial operations? Kakadu for jpeg2000 is written in C++. Do you have some benchmarks where Rust could outperform C++?

Do you prefer any typechecking lib/tool or just React? Or.perhaps TDD? recommendations?

When are styled components 2 supposed to be released?

I'm also coming from pure JS/jQuery to React world, but working at the firm that works in GWT (and hate it very much). What's the arguments would you give to ditch GWT in favor for some more modern framework/lib? :)
