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.

[johnnyutah]

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

[adamlerman]

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

[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!

[chrisvetrano]

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

[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)

[JulioDx]

Thanks for this series, I am learning a lot.

[oykfwrl]

Sincerely thank you for all these quality videos buddy!

[zykoz]

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

[TheRFracer]

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

[zykoz]

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

[pratikmakune]

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.

[falias]

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.

[francis_n]

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?

[jimshtepa]

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?

[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

[raminkhodaie]

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

[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.

[justinmooney]

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",
}

[hadeedtmgggg]

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