Overview

Pattern: Sequential array index assignments -> parallel assignment

When assigning multiple variables from sequential array indices (0, 1, 2...), Ruby's parallel assignment syntax is more idiomatic and can be slightly faster as it avoids multiple array access operations.

Example:

# Before
a = arr[0]
b = arr[1]
c = arr[2]

# After
a, b, c = arr

Impact: Minor performance improvement, but more idiomatic Ruby
