golang-samber-loFunctional programming helpers for Golang using samber/lo — 500+ type-safe generic functions for slices, maps, channels, strings, math, tuples, and concurrency (Map, Filter, Reduce, GroupBy, Chunk, Flatten, Find, Uniq, etc.). Core immutable package (lo), concurrent variants (lo/parallel aka lop), in-place mutations (lo/mutable aka lom), lazy iterators (lo/it aka loi for Go 1.23+), and experimental SIMD (lo/exp/simd). Apply when using or adopting samber/lo, when the codebase imports github.com/samber/lo, or when implementing functional-style data transformations in Go. Not for streaming pipelines (→ See `samber/cc-skills-golang@golang-samber-ro` skill).

Use Map and Filter to transform and filter order data, and GroupBy to aggregate orders by status. This reduces boilerplate code and improves readability when processing large volumes of e-commerce transactions.
Chain Map, Filter, and Reduce to transform and analyze streaming data in batches. Immutability ensures predictable state, and lazy iterators (loi) can be used for large datasets to save memory.
Apply Uniq and Filter to deduplicate and filter user records from multiple sources. Use Flatten to merge nested permission groups into a flat list for easier authorization checks.
Use lop (parallel package) to concurrently fetch data from multiple API endpoints and combine results with Map. This speeds up CPU-bound processing of large slices (1000+ items) without complex goroutine management.
Leverage MapErr and FilterErr to validate a list of config entries, stopping on first error. This provides clean, composable validation logic without nested if-statements.
Companies using samber/lo benefit from reduced development time and fewer bugs in data transformation code, leading to faster feature delivery. The library is free but improves developer productivity.
Consultants can offer training on functional programming patterns in Go using samber/lo, helping teams modernize legacy codebases. Revenue comes from workshops and code reviews.
SaaS platforms integrating samber/lo for internal data processing can reduce compute costs by optimizing transformations (e.g., using mutable variants in hot paths). This improves margins.
💬 Integration Tip
Start with the immutable core package (lo) and only migrate to lop, lom, or loi after profiling demonstrates a bottleneck. Use Context7 or the official docs to explore the full API surface.

Control desktop applications on Windows — launch, close, focus, resize, move windows, simulate keyboard/mouse input, manage processes, control VSCode, read clipboard, and capture screen info. Use when the user wants to interact with any running program, switch windows, type text, press shortcuts, open files in VSCode, manage running processes, or get system display information.
Conduct rigorous, adversarial code reviews with zero tolerance for mediocrity. Use when users ask to "critically review" my code or a PR, "critique my code", "find issues in my code", or "what's wrong with this code". Identifies security holes, lazy patterns, edge case failures, and bad practices across Python, R, JavaScript/TypeScript, SQL, and front-end code. Scrutinizes error handling, type safety, performance, accessibility, and code quality. Provides structured feedback with severity tiers (Blocking, Required, Suggestions) and specific, actionable recommendations.
Pragmatic coding standards for writing clean, maintainable code — naming, functions, structure, anti-patterns, and pre-edit safety checks. Use when writing new code, refactoring existing code, reviewing code quality, or establishing coding standards.
