Replace Control Flag with Break

Goal

Loops that maintain a boolean to decide when to stop replace it with a direct `break`, `return`, or `continue`.

Before the refactoring

let found = false;
for (const p of people) {
  if (!found && p.name === target) {
    matched = p;
    found = true;
  }
}

After the refactoring

for (const p of people) {
  if (p.name === target) {
    matched = p;
    break;
  }
}

Savings

The exit condition appears at the moment it's decided, not as a delayed effect of a flag check; the loop's intent becomes literal.

Note

If the loop body is large, the break can hide the early-exit semantics — extract a function around the loop's body to keep the exit obvious.
