Boolean prefix (ARCH3007)

Key typescript.naming.boolean-prefix · Severity info · Category naming

Boolean-typed members and accessors should carry an interrogative prefix (is/has/can/should). Without one, conditionals read unnaturally and intent becomes unclear.

Incorrect

class User {
  active: boolean = false;
  admin: boolean = false;

  delete(): boolean {
    return this.admin;
  }
}

Correct

class User {
  isActive: boolean = false;
  isAdmin: boolean = false;

  canDelete(): boolean {
    return this.isAdmin;
  }
}

Fix

Add an appropriate interrogative prefix to the boolean member: is, has, can, or should.
