This test checks whether various seal/freeze/preventExtentions work on a regular object. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". PASS (new inextensible).prototypeExists is true PASS (new sealed).prototypeExists is true PASS (new frozen).prototypeExists is true PASS test(obj()) is "(b:4)(c:3)E" PASS test(preventExtensions(obj())) is "(b:4)" PASS test(seal(obj())) is "(a:1)(b:4)S" PASS test(freeze(obj())) is "(a:1)(b:2)SF" PASS Object.preventExtensions(Math.sin) is Math.sin PASS var o = {}; Object.preventExtensions(o); o.__proto__ = { newProp: "Should not see this" }; o.newProp; threw exception TypeError: #<Object> is not extensible.
