海外TECH	DEV Community	Object.freeze vs Object.seal in Javascript	https://dev.to/damcosset/object-freeze-vs-object-seal-in-javascript-3kob	Object freeze vs Object seal in Javascript Object freezeHere is how you use Object freeze let objectToFreeze age name Damien pets Symba Hades Kiwi sibling age name Corentin Object freeze objectToFreeze Object freeze takes an object as an argument Note that it modifies the object you pass as argument It does not copy the object and create a new one So what does it mean for the object You can t add new properties to the objectYou can t modify the properties if they are not objects or arrays themselves More on this later You can t delete properties from the objectlet objectToFreeze age name Damien pets Symba Hades Kiwi sibling age name Corentin Object freeze objectToFreeze delete objectToFreeze age objectToFreeze name Ben objectToFreeze pets push Grenade objectToFreeze sibling age objectToFreeze lastName Cosset With the description I just gave you you should guess what the object will look like now console log objectToFreeze objectToFreeze age name Damien pets Symba Hades Kiwi Grenade sibling age name Corentin The delete failed modifying the name property failed and adding the lastName property failed But modifying the array worked Note If you are not in strict mode it will fail silently In strict mode you will get TypeErrors use strict let objectToFreeze age name Damien pets Symba Hades Kiwi sibling age name Corentin Object freeze objectToFreeze delete objectToFreeze age Throws this Shallow freezeWhat we have when we call Object freeze is a shallow freeze We only freeze what is directly attached to the object Properties inside objects and arrays are not concerned To make the entire object and everything inside immutable you have to call Object freeze on every element Here is one way you could do this let allYouCanFreeze gt Retrieve the properties names let propNames Object getOwnPropertyNames obj Loop through the properties If typeof is object meaning an array or object use recursion to freeze its contents for let name of propNames let value obj name obj name value amp amp typeof value object allYouCanFreeze value value Finally freeze the main object return Object freeze obj Let s use it on our first object let objectToFreeze age name Damien pets Symba Hades Kiwi sibling age name Corentin allYouCanFreeze objectToFreeze Now we can t touch the pets array and the sibling objectobjectToFreeze age Now fails objectToFreeze pets push Grenade Now failsGreat Now our sibling object and our pets array can t be modified Object isFrozenTo know if an object is frozen you can use Object isFrozen Object isFrozen objectToFreeze truelet unfrozenObj a Object isFrozen unfrozenObj false Object sealObject seal like the freeze method takes a object as an argument Object seal is a softer version of Object freeze You can t remove or add elements to the object You can modify existing properties let objectToSeal name Damien age pets Symba Hades Kiwi sibling age name Corentin Object seal objectToSeal Pretty straightforward huh Let s try to modify this object now delete objectToSeal name objectToSeal age objectToSeal lastName Cosset objectToSeal sibling age objectToSeal pets push Grenade Maybe you already guessed what should happened objectToSeal new contents name Damien age modifying worked pets Symba Hades Kiwi Grenade push worked sibling age Modifying worked name Corentin adding and deleting failed Notice that just like Object freeze Object seal will fail silently in non strict mode and throw a TypeError in strict mode Object isSealedWe also have a method to know if an object is sealed Quite explicit we can call Object isSealed to know that Object isSealed objectToSeal truelet notSealedObj a Object isSealed notSealedObj false What about const You might be tempted to look at Object seal and Object freeze and compare them to const Remember that they are different concepts Object freeze and Object seal apply on the values of an object and const applies on the binding Object freeze makes an object immutable const creates an immutable binding Once you assign a value to a variable you can t assign a new value to that binding What about prototypes One last thing I need to mention prototypes I ve writing an article about Javascript prototypes if you are not familiar with it When it comes to Object freeze and Object seal know that you also can t change their prototypes once they are frozen or sealed let freezeThat name Damien let sealThis age Object freeze freezeThat Object seal sealThis These two lines will fail Object setPrototypeOf freezeThat x Object setPrototypeOf sealThis alive true setPrototypeOf is used to change the prototype of an object When the object is sealed or frozen you will not be able to do that As always in non strict mode it will fail silently In strict mode you will see a TypeError Object is not extensible ConclusionIt s important to know the differences between Object freeze and Object seal Being aware of those differences will avoid you some trouble when you use them in your code To recap	2020-06-02 18:17:35
