Unlock the Secrets of Range Loops: How Element Evaluation Affects Your Go Code | HackerNoon
Briefly

Range loops in Go create copies of values, leading to potentially confusing behavior when modifying elements, particularly with address references in iterations.
The issue arises when using a single variable in a range loop. Because the variable represents the last element after completion, it can introduce bugs.
It’s crucial to understand the copying behavior when using range loops. For slices and arrays, iterating can create unexpected results if not handled correctly.
To avoid subtle bugs, ensure that if you're working with pointers, you capture the value at each iteration to maintain the intended data.
