go-extend is a Go utility library that collects commonly used helper functions to speed up development and reduce repetitive code. It provides performance-optimized alternatives to standard library functions like strings.Join, strings.Repeat, and strings.Replace, often using unsafe and in-place techniques to reduce memory allocations.

Use cases

• join strings with fewer memory allocations in Go
• repeat or replace large strings efficiently
• convert string operations to []byte without type conversion overhead
• find optimized replacements for Go standard library string functions
• reduce boilerplate utility code in Go projects
• benchmark and compare performance of string manipulation functions

When to choose

• your Go application is performance-sensitive and string/byte operations are a bottleneck
• you want drop-in, faster alternatives to strings.Join, strings.Repeat, or strings.Replace
• you need a curated set of common utility functions to cut down repetitive code

When to avoid

• you prefer to avoid unsafe-based code paths in safety-critical or audited codebases
• your project only needs one or two small helpers and you'd rather write them yourself
• you need actively maintained libraries with frequent updates and broad community support
