Go - Best practices
summary
Covers concrete Go gotchas and fixes: examples show pass-by-reference for slices and arrays so modifying a slice updates the original backing array; := variable shadowing creates unexpected local variables; slices keep larger capacity and share addresses; len counts bytes so use RuneCountInString for Unicode; ^ is unary bitwise NOT and binary XOR; defer evaluates call arguments immediately and defers execution LIFO; loop-closure goroutines require copying loop vars; use labeled break to exit nested loops and recover only inside deferred functions.
