TypeScript Crash Course 2021 | The Basics From Scratch!

In this crash course, we're going to take a look at TypeScript. I'll teach you what it is and how you can use it in your next project.

TypeScript is a superset of JavaScript. That means that it can do everything that JavaScript can but adds more features.

The types that we'll cover are: string, number, boolean, array, object, any, void, null and undefined, tuple, enum, and generics.

I've watched several videos explaining TS basic concepts, this one is the easiest to grasp. Thanks a lot and looking forward to further videos on using TS with React and Node :)

[madhousenetwork]

Typescript always gave me a fear of understanding but you made it overcome it with a lot of simplification. thanks!

[nerdiloo]

Really good lightweight, easy going 40+ min tutorial, and will recommend. Good one bro.

[iUmerFarooq]

I just complete the Typescript course from other channels And you come up with this tremendous course 😉
Thank you ❤

[IkraamDev]

I was thinking about learning TypeScript. Thank you!

[irfangumelar]

This one of the best typescript course I've found on youtube

[masoodkhanpatel]

Coming from C/C++, Java, OOPs background, Typescript just feels like home! Thank you!

[miyasmohammed]

Thank you for making this video more useful.
Learned concepts of TS.
Love this video and subscribed.

[pouyajabbarisani]

Best TS tutorial so far, It would be even better if you add a part 2 for this video (to include some advanced topics, too) also probably a video for TS in React.

[simonkalu]

You're good at what you do... I can recommend this to new joiners at the place I work.

[bronxandbrenx]

I like this :). Thank you for sharing on how to use Typescript for HTML Elements.

[saurabhtalele]

Awesome sir looking forward to go get advance training from you

[zmanphx]

Awesome introduction. I look at TS as applying c# typing to JS.

[wmblemania]

Thank you for this. These catch-up videos are invaluable.
Coming back to JS every now and then from other (type-safe) languages, it still baffles and frustrates me as to why _modern_ Javascript (or, rather, ES) isn't type-safe by default.
JS still feels like a junk, toy language, full of terrible design decisions. Most of which could have been fixed in modern standards. It's not like JS's problems aren't well known.
The fact that we need tools like TypeScript says it all.
And yet people keep defending JS, and hand-waving away all its flaws. It's like they never learned what a well designed programming language is supposed to look like, and so think that JS is some kind of best practice. Inertia can be a terrible thing...

What theme are you using? I like the way the cursor.blinks!

[bmehder]

Thanks for the tutorial. What VS Code theme are you using?

[dominik-bh]

Sorry if this is a stupid question but in Classes and Interfaces
since we're defining the type as string and number in the Interface, why do we need to repeat that in the Class?
I thought that "Class implements interface" would be something like "extends"?

[mohammedalkhalaf]

I really miss your useful videos which have a huge amount of knowledge.

[mubashirarif]

Awesome crash course...keep up the good work Sir
