JSX is a statically-typed, object-oriented programming language designed to run on modern web browsers. Being developed at DeNA as a research project, the language has following characteristics. faster JSX performs optimization while compiling the source code to JavaScript. The generated code runs faster than an equivalent code written directly in JavaScript. The gain may vary, but even the optimi
A language empowering everyone to build reliable and efficient software. Performance Rust is blazingly fast and memory-efficient: with no runtime or garbage collector, it can power performance-critical services, run on embedded devices, and easily integrate with other languages. Reliability Rust’s rich type system and ownership model guarantee memory-safety and thread-safety — enabling you to elim
