Replace Inline Code with Function Call

Goal

When inline code reproduces what a named function already does, the inline copy is replaced by a call.

Before the refactoring

const inRange = candidate >= low && candidate <= high;

After the refactoring

const inRange = between(candidate, low, high);

Savings

One canonical implementation; the name labels the intent; future improvements to the function reach every site that used to inline.

Note

If the existing function's name doesn't quite match the local intent, the call site reads as a near-miss; consider Change Function Declaration first.
