Using `assert.AssertionError()` without the `new` keyword results in a non-intuitive error: ```js > assert.AssertionError({}) TypeError: Cannot assign to read only property 'name' of function 'function ok(value, message) { if (!value) fail(value, true, message, '==', assert.ok); }' at Function.AssertionError (assert.js:45:13) at repl:1:8 at realRunInThisContextScript (vm.js:22:35) at sigintHandlersWrap (vm.js:98:12) at ContextifyScript.Script.runInThisContext (vm.js:24:12) at REPLServer.defaultEval (repl.js:346:29) at bound (domain.js:280:14) at REPLServer.runBound [as eval] (domain.js:293:12) at REPLServer.onLine (repl.js:545:10) at emitOne (events.js:101:20) > ``` The `assert.AssertionError()` can only be used correctly with `new`, so this converts it into a proper ES6 class that will give an appropriate error message. This also associates the appropriate internal/errors code with all `assert.AssertionError` instances and updates the appropriate test cases.
