Is Haskell safer than Rust?
While Haskell generally has better safety guarantees than Rust, there are some cases where the explicit tracking of lifetimes and thread safety—versus Haskell’s garbage collection and explicit-mutable-types—produces a safer result.
Why is Cardano written in Haskell?
The paradigm of Haskell is functional programming. The language forces you to write functional code. This is exactly why the Cardano blockchain chose Haskell as their main driver — they describe it as a great choice for building reliable code, which is essential for building a blockchain.
Is Haskell still used?
There are a few reasons for this. Firstly, Haskell is still primarily used in academia and research. There are companies that use it (see list above) however, even they struggle to find good candidates that have experience. It can be rather complex and so not a lot of new programmers will try to learn it.
Is Haskell difficult to learn?
Even among the functional languages Haskell is especially hard to learn. This is due to its terse syntax, abstractness, purity, and its community’s love of one letter identifier names. Many of these things give Haskell unique strengths, but they also make it hard to learn.
