No BS TS #11 - Enums and Literal Types in Typescript

[@achillesnakmuay]

Dude these videos... I've been developing professionally for 7 years and this is one of the easiest to digest channels I've ever come across.

[@adamlerman4173]

I never comment on youtube (or anywhere really) but I felt like I just had to let you know, these videos are the single most valuable thing I have found in order to learn ts. THANK YOU SO MUCH

[@johnnyutah23]

Today I learned I've been pronouncing enums wrong all this time! Great videos!

[@zykoz6826]

Enumerations are one of my favorite ways to keep code clean!

[@zykoz6826]

Literally the best `${...content}` around. No BS

[@pratikmakune2881]

Absolutely loving your content Jack. Thanks so much :) Can you please also suggest any course for Object-Oriented Programming/Designing using Typescript in greater depth, I have upcoming assignments on those lines.

[@techhguy]

One Word Description = Awesome!

[@JulioDx3480]

Thanks for this series, I am learning a lot.

[@arghyamitra3281]

U sir becoming my favourite

Great video as always Jack. Have a question. When you constrain the values to rollDice function, what happens if the callee pass it argument which is a variable and it is not in the constrained value range of 1 | 2 | 3 | 4?

[@jherr]

I think you'd have to assert that it's one of those values.

[@raminkhodaie4063]

what if we want to implement the last concept and example with concept of arraow function?what would be the code snippet for this? the example at 6:00

[@jimshtepa5423]

Another very informative material. Thank you, Jack. A quick question: the englishLoadingState object you defined at 2:50, was it intended to explain enums? or use of enums? Could you please clarify what was it you wanted to demonstrate?

[@Blumi]

I love this series but imo it should be Math.random() * 6, not 5.

[@jherr]

Yeah, true.

[@BHFJohnny]

Just out of curiosity, I found that fully symmetrical 5-sided dice is not possible (At least in 3d world), but there's a symmetrical 10-sided dice where each value is present twice. Who'd knew, huh? 🤔

[@yokevinmendez]

Good video, I just want to say; I prefer always use literal types instead of enums, because use literal types is more readable for me.

[@jherr]

I kinda go back and forth on it myself.

[@justinmooney1398]

These videos are terrific.Here's something I've never quite understood though: What is the advantage of using an enum (particularly if you assign strings as the property values like you've sensibly done here) over just using a regular js object and referencing properties from that object. Do you have any insight to this, Jack? enum LoadingState { beforeLoad = "beforeLoad" loading = "loading", loaded = "loaded", } const loadingState = { beforeLoad: "beforeLoad" loading: "loading", loaded: "loaded", }

[@jherr]

Problem with the const version is that your signature would look like `isLoading(state: keyOf loadingState): boolean` as opposed to `isLoading(state: LoadingState): boolean`.

[@justinmooney1398]

Ah, makes sense. Thanks for quick reply.

[@alaxalan3667]

Awesome :)

[@kettenbach]

loaded ☝️😀

[@dannyroberts4067]

I like this guy, he's obviously an amazing dev'. I would suggest however that he slows down and spends a bit more time explaining, I feel like he doesn't seem to enjoy the teaching and just rattles through what he's doing in the moment.

[@kncle]

I have a question. Why would I use an enum when I can create a type with unions instead? It has the same functionality but doesn't require the dot syntax. Also easier when looking at values for example, coming from a JSON file I found. Love the videos. I love typescript and I had no idea howm many features it had until I saw your series

[@flibben]

Wow, string literals with function overloads - so cool! Didn't even know what function overload was before this video. Thank you for all the quality content, keep it up!

[@hadeedtmgggg5837]

My string literal code give all two option although I write the same code

[@TheRFracer]

Absolutely top content... the best TS course you can find on youtube

[@falias4]

Great content so far! I also started with enums but I prefer the union type whenever possible.. unless there's a hard reason for an enum.

[@大盗江南]

Sincerely thank you for all these quality videos buddy!

[@meyourstubes]

never learned so fast in that short time. Thank you so much. I really like your speed and detail level; in conjunction with good hints and background, where to use it, and what to avoid. (: fun-fact, it's a loaded dice; please use "rand() * 6 + 1" if you ever want to have a 6 as result)

[@chrisvetrano8282]

Amazing videos... I needed a TS refresher course after being out of TS for 8 months and this has been perfect. Thank you.
