| • Introduction to functional programming in Go
|
| • History of functional programming in Go and impact of generics
|
| • Recap of functional programming basics (functions as mappings, composition, currying)
|
| • Map function for applying functions to each element in a slice
|
| • Flat map function for combining multiple lists
|
| • Filtering and zipping operations using functions
|
| • Pure functions and their application in programming
|
| • Type parameterization and its implications on function implementation
|
| • Generics in Go and how they enable type-safe functions with compile-time guarantees
|
| • Elimination of boilerplate code and reflection in functional programming libraries
|
| • Benefits of generics for library authors and users, including simpler interfaces and compile-time type checking
|
| • How generics work behind the scenes in Go, generating instances of generic functions for each supported type
|
| • Efficiency gains from using generics in writing functional programming libraries
|
| • Cautionary approach to using generics in Go, emphasizing need for experimentation and best practices
|
| • Discussion on whether functional programming (FP) should be used in production code, given its capabilities in Go
|
| • FP already present in Go through features like context and functions as first-class citizens
|
| • Imperative vs declarative differences in programming styles, with FP representing a more declarative approach
|
| • Benefits and challenges of applying functional programming (FP) concepts to Go codebases
|
| • Importance of declarativity in reducing lines of code, adding structure and readability, and fixing bugs
|
| • Education and awareness as key factors in adopting FP concepts in existing codebases
|
| • Potential features in Go that could enable more widespread use of FP concepts, such as type parameters on methods
|
| • Higher-kinded types as a complex feature that could offer advanced type constructions but add complexity to the compiler
|
| • Definition of lens: a tuple of two functions (getter and setter) for accessing and modifying data
|
| • Lenses can be used to simplify code by reducing the need for getters and setters
|
| • They are typically closures that take parameters and return values or errors
|
| • Type systems, specifically in Rust and Go, were discussed as being important for concise and readable programs
|
| • Aaron Schlesinger's education background: he has a Computer Science degree from 2008 and is currently pursuing a master's degree with a focus on formal methods
|
| • Rust has more features than Go, but also allows for longer compilation times
|
| • Aaron Schlesinger compares and contrasts Rust with Go from his experience
|
| • He finds Rust allows for more expressive code with fewer lines than Go
|
| • Aaron still loves Go, finding it ideal for quickly building things
|
| • Discussion touches on functional programming and generics in Rust |
