Haskell vs. PureScript vs. QShield vs. dbForge Query Builder for SQL Server Comparison Chart

Every expression in Haskell has a type that is determined at compile time. All the types composed together by function application have to match up. If they don't, the program will be rejected by the compiler. Types become not only a form of guarantee, but a language for expressing the construction of programs. Every function in Haskell is a function in the mathematical sense (i.e., "pure"). Even side-effecting IO operations are but a description of what to do, produced by pure code. There are no statements or instructions, only expressions that cannot mutate variables (local or global) nor access state like time or random numbers. You don't have to explicitly write out every type in a Haskell program. Types will be inferred by unifying every type bidirectionally. However, you can write out types if you choose, or ask the compiler to write them for you for handy documentation.

Obfuscate your highly valuable source code and protect your sensitive assets thanks to QShield compiler-obfuscator. Protect your applications against static and dynamic analysis. Software running on untrusted environments is at risk of reverse-engineering, an application running on a device that is available to an attacker is vulnerable to a wide range of techniques used to try and extract secrets, and intellectual property. To prevent unauthorized parties from gaining insight, tampering with or even recovering the source code from the binary, software protection mechanisms must be implemented to preserve revenues and intellectual property. 30+ obfuscation schemes are available. Granular control of the protection profile thanks to a file-based policy or comments throughout the code. Build diversification, each compiled application is different with a user-controlled randomness seed. Integrity checks and detection of debuggers, emulators, and hooking frameworks.
