GoLang — Optimisations

Go- Arrays:

1. When iterating over an array it’s faster to pass a pointer to that array to the for loop. This prevents the loop from copying the whole array which is beneficial for both CPU and memory usage.

2. If we want to modify the array while we’re iterating over it, we need to either give a for loop a pointer to that array or use the array index operator directly.
