When your Enum is backed by data in a DB, I've found that using "pojo as const" isn't quite as nice of an alternative. For example, I have "UserRoles" represented in my DB as 1-indexed integers, and find that using an enum backed by 1, 2, etc. is a very convenient way to reference those db values in my code in a very human-readable way. Using ints also allows me to sort my roles hierarchically and perform gt/lt comparisons which I wouldn't be able to do with pojo as const. I can also quickly rename any of my roles in code w/o needing to do a db migration. All that said, I am relatively quite new to TS as compared to other languages, so there may be a better way to achieve what I want w/o enums. If anyone has suggested alternatives I'd be happy to hear them!
I think there's definitely a case for both. One benefit of using a POJO is that, particularly for a library, you may want your consumers to just pass in a string value rather than also needing to import the enum and using that. Overall more flexible in that regard I think. I'd also add that when I use enums, they're always fully defined with explicit value, I don't want automagic values in there because those automatic values are bound by their order, so if you re-order the keys in your enum, but were expecting an index value in a different system (e.g. when sending serialised data), then you'll end up with problems the type system can't help you with.
Based on Matt's video, I've already made the transition to POJOs. I like the flexibility of hardcoding strings, while still getting error checks and intellisense
Easy to use: const roles = { admin: 'admin', user: 'user', } as const type Role = ValueOf declare type ValueOf = T[keyof T]; I have no idea why you need "enum" If you will have library enum and codegen enum(from prisma / gql for exmaple) and they will be identity or one of the options would be more of a narrow type, they'd all be incompatible do you know how devs fix it? just cast, nice "safety" method (nope) Nobody must use enums, it must be removed
I see your point, and I agree that most of people wouldn't be able to understand Matt's alternative (yet produce it, or even use it effectively in a codebase). But at the same time I think it's important to point out few things. 1. The use of reverse mapping is beyond just calling a method with a string where we should've used the enum, it's the ability to get the enum from a string (e.g. you have an error status code, and you want the get the enum from it. Or you have string file names and you want to get the enum for the extensions ...). 2. Why enum in general feels "odd" in the world of TS is because they behave differently. TS type system is based on the "shape" of the objects, (i.e. if object A is of type Person, and object B is of a type that fits the description of a person, then we can use B where we used A and viceversa). You cannot do that with enums as Matt explained, and that's enough reason for me to at least try to avoid them when possible, specially for TS newcomers because it will confuse them. With that said I loved the video, and I loved how you respectfully shared your opinion while giving credit to Matt 🎉
I respect Mat's wisdom on typescript, but I am team Enum. I love the strictness, though I also use the "POJOs" it just depends on how I want to use something.
I think this is the problem of typescript and JavaScript in general to always add different rules and work around that lead to misunderstanding and always provoking feelings of skill issues. Getting some interest to strict typed languages you realize that these native features are working as expected you have to learn how and when to use them. Enums are great and following the typescript documentation they have to be used in a certain manner. Great video
YEAH, Matt and other "typescript masters" or whatever the hell they are called are 100% using typescript for the only sake of typescript itself, like using english language to write a poem. But we use typescript to make programs do stuff lol, and James take here is much more honest and practical
TS currently follows a “duck typing” system. ie if two types are the same you can use them in place of each other. TS also has a philosophy of having TS disappeared in transpilation or in other words TS shouldn't leave code artifacts behind. Enums are the exception to this because it was early in the TS life and these philosophys hadn't been added. Matt and others like him advise against Enums because they go against the grain of TS in its current state
I actually agree with you more on these points. When we write enums, we're signaling to the reader that these values come from a predefined, limited set.
If devs are calling object methods on enums or try to circumvent them by passing hardcoded values instead, they have missed the point of enums. Any unexpected behavior that arises from such misuse is not the language’s fault.
Pocock's magic typescript is just using a keyof operator which every typescript dev should use. I think the disagreements about being able to use strings instead of enums is a good consideration but just a preference and depends on what you're trying to do in the code
Great point at 8:33 . Sometimes you work with javascript codebase and people whom you try to convince to switch to Typescript. The simpler the better in those cases. It all depends on context.
the point is basically 'i am dum dum, so as const is bad and enums are good' and don't talk to people who need to be convinced to switch to TS in 2024. These are dinosaurs
@@VladyslavAvidzbaBS. Of course TS is excellent, but there are also alternatives and cases you don't have to require type safety. Just like in plain-old Python, for example. Also, your first point is also dumb, because that's not the reason people defend Enums. Once you define values in an Enum, it is basically the same thing as POJOs, just without ther overhead of writing types to get the POJO's keys/values type.
I like both. I don’t feel like enums deserve all the hate. I can say I have ran in to edge cases with both that I found frustrating. So I tend to use an enum if I am going to build tightly coupled components and I don’t intend to share the enum around my app or apps. I use the as const if I’m building something that needs to be more generic and can be shared and reused all over. But per your comment in the video. If the intent is to have teammates use exact strings that I know might change I think the enum is the right tool.
I think what really comes into play here is your background. If you come frome an OOP background (like Java) you probably really want to always pass it like you said (ENUM.ATTRIBUTE). But if you come from a JavaScript background I think you might have another mental model where TypeScript is not OOP in JavaScript but instead just forces you to pass the right things and you might prefer that you are able to pass the values instead of ENUM.ATTRIBUTE as well. Because for example you could define a type have that type as a paramter but you dont have to ACTUALLY pass that type. You just have to pass something that looks the same as that type. E.g. you can make two type aliases that define the same object and use them interchangebly throughout the code. That is not what someone coming from OOP would expect but it is how TypeScript works. So "Matts Enum" is more in line with that.
The first example in your tweet makes no sense if you’re only using those strings within className? Why not make a specific tailwind class with those sizes?
in every legit language enums get numeric indicies to store the information in lesser memory units. it IS what i would expect of an enum. it's js thats 💩
4:34 If you're working in a company like mine where you have like 20+ packages, this can get really cumbersome. We have rules to not import from the src directory which means all the enums you use for a component property in a package need to be exported explicitly. Often when someone else builds a package you're using and for example, you're trying to inherit a type(with enums) from it, it can be so problematic because that enum has to be exported explicitly while union with values solve so many of these issues.
There is nothing wrong with passing nromal strings if everything is typed correctly. That's the whole point of TS. Not sure what you point was in 4:45min. TS will check the value itself if you type it correctly, so there is no problems there. I stopped watching, i should start making videos honestly...
I just don't see any valuable reason to use enums over type literals or objects except when it comes to log levels examples. People usually use enums for values that aren't supposed to change or to avoid typing the same string all over the codebase in case they need to change it. And that's my biggest issue with enums is that they allow you to change their underlying value and typescript will think everything works as expected. It's especially worse for DB related stuff because the underlying value should never change and get out of sync with your db. Just found this issue in our api a few weeks back. I'd much rather hardcode strings and rewrite the same string in multiple places and get a typescript warning all over the codebase when someone tries to change that value as opposed to enums saying everything is fine. It's too easy for a dev to come and change the values of the enum due to whatever reason and not realize that this value is how it's stored in the DB and lead to all sorts of issues.
Regular ENUMS as you have used is 100% the way to go. For me this removes the need for hard coding strings. If you haven’t worked in a large repository before you don’t know how bad hard coded strings can be especially when refactoring. Plus the example with POJOs is simply more code to get the same functionality from a traditional enum using a key and value.
I like Matt's version but comment it do to I underestand it is hard to understand. If you want to just use a key and the value does not need to be different can use an array as const with a bit of TS.
I watched it before Matt's video, with as const another set of problems opens up :D, something like this Array of Foo not assignable to Readonly Array of Foo so I use both things interchangeably enum Status { Close = 0, Open = 1 ...etc} I have a lot of things stored in the database like this as a integer
Getting to a point (with TS) when i need to rename keys, cascade from one type into a new type or other advance TS, in my humble opinion means you didn’t do your stuff right from start and when i say start, i mean diagrams, scenarios, before first line of code. Beside this, have one of “Matt” in team, with his advance TS level will only get latency on development, lets not forget for what TS is made: enforce addresses to accept type, avoid js dynamic type. Or maybe im wrong 😑 Oh and beside this, “as const” beside making it readonly, you can use it as type, the type being the literary value not type of const value. Basically another kind of Enum with keys value defined.
For me the only reason to use enums is Data Base, I wan't to restrict the column values to a set of strings (or numbers). Other than I either use a POJO or a string type (type MyString = 'foo' | 'boo')
Same guy that wrong c# wrote typescript. Enums are a staple of c# they are a value type and work the same way. Typescript isn’t applied when you reading PRs from GitHub. Being able to quickly distinguish between strings and Enums is very valuable. To many things look like a hard coded string in JS/TS
I've used both kinds probably just as much as the other, and I honestly think if you're looking to make something rigid, go with Enums, they are simpler to define, and there's only one way to use them so there will be consistency in the code. Freedom sometimes takes away the consistency imo.
I could be wrong but using “as const” object as alternative to Enum isn’t new and is a widely used typescript pattern. So personally I don’t see why it’d cause confusion. And this pattern is even mentioned as alternative in modern typescript in the typescript official documentation under the Enum section. My personal preference is to stick with object because it’s predictable vs you get so many quirks with Enum.
I'm not saying "as const" specifically causes confusion. I think the TypeScript that comes with it to get typings adds some confusion though. Regardless, I agree, it's a perfectly valid way to do this
I've a pretty nice example for the last plain javascript part, I'm in a situation where i need types value in booleans with associated name for developing. tried to use enums but it does not infers into booleans. I can use this as const method to declare types of " transaction = { Debit : true } " that made it pretty easy.
Ever since I have discovered as const, I can't really go back to enums. I have used them before, but moved over to using string unions instead. The downside of unions is the inability to iterate over them, hence as const is a nice way of solving all the issues and limitations of enums and alternatives.
Excellent topic and great counterpoints. Aside from the weird index thing, I agree with you that they behave exactly as I would expect them to with no added complexity. Yeah Matt is the 🐐 for Typescript. 💪

Great vid. Would I use Enums or 'as const objects'? I think the answer as always is "it depends". But I do tend to lean a bit more towards objects than enums.
