The plain-English version
Expressing operations over collections through array-oriented functions rather than explicit high-level loops.
Why it matters
It can reduce interpreter overhead and make mathematical structure clearer.
Let’s make it click
Compute a column of residuals with an array subtraction before aggregating error.
Vibe Bro’s heads-up
Vectorized code can allocate large intermediates; measure memory as well as runtime instead of assuming shorter code is always more efficient.

Supported: Vectorization can reduce interpreter overhead while increasing temporary-array memory; no universal speedup is claimed.
