@studnicky/v8/with-statement

Disallows with statements. The with statement makes scope resolution dynamic — V8 cannot determine at compile time which binding a variable name refers to, so it cannot generate optimized code for the entire surrounding function.

✗ Incorrect

// @ts-ignore — shown for documentation only; with is not valid in strict mode
with (Math) {
  const r = sqrt(pow(x, 2) + pow(y, 2));
}

✓ Correct

// Use explicit object access
const r = Math.sqrt(Math.pow(x, 2) + Math.pow(y, 2));

// Or destructure once at the call site
const { sqrt, pow } = Math;
const r = sqrt(pow(x, 2) + pow(y, 2));
