Agda
Agda is a dependently typed functional programming language and proof assistant used for formal verification and theorem proving. It allows developers to write programs with precise types that can encode mathematical properties, enabling the construction of proofs about program correctness. It is based on intuitionistic type theory and is often used in academic and research settings for verifying software and mathematical theorems.
Developers should learn Agda when working on projects that require high assurance of correctness, such as in safety-critical systems, cryptography, or formal methods research. It is particularly useful for verifying algorithms, proving properties of programs, and exploring advanced type systems, making it valuable in fields like programming language theory and formal verification.
