Does Rust replace JavaScript?

How much faster is Rust than JavaScript?

They rewrite the rust code to eliminate the extra allocations they identified at the end of this post. It then performs 8 times faster than the javascript version.

Is it worth learning Rust in 2020?

Rust: low-level language with abstractions from higher-level languages. The low-level language Rust is so efficient that it can do without automatic garbage collection. Nevertheless, it offers the performance of C and C++, but without the pitfalls that developers have to know and consider at work.
