TypeScript Mapped types explained

Mapped types are a great way of transforming existing types into new types. In this video tutorial, you will learn how to create mapped types and how to leverage mapped types in your project to transform read-only interfaces into interfaces with optional properties or even how to transform a simple interface into a type that defines getters.

I was impressed by the capitalization trick in the end - I think, it requires more attention with more explanation and examples. PS Please get a decent microphone as it will increase your audience. Hope to see more tricks from you!

Thanks for sharing. P.S. Intro music too loud and sudden.

[@AlainBoudard]

Excellent techniques ! Thanks for sharing.

How did you first example work when the there was typo in `Proeperty`? This technique looks very convenient?

[@shemmuthanga6352]

It is just a variable name, not a keyword. If in the second example, he used 'Proeperty' and 'Property', it would throw an error

I get that this is somewhat advanced usage. But where do we draw the line between readability and flexibility? 6:30 is great but certainly very complex from a readability standpoint.

This feels awesome, but I cant really explain why. Can someone explain some real use-cases where classes would not be the better choice?

[@peterjordanson4201]

Hi, just a constructive feedback here: your intro is too loud. Either remove the intro or lower the volume by a lot. Thanks for the video. Cheers

Cool but in terms of readability and maintainability, I don’t think it adds value

[@limerickgangster]

But it would be 100 times better if you would use it on some code.
