Type safety in enterprise-grade applications is a must, this could avoid random errors coming via unknown and rarely traversed JS code flows.

At least LWC should have a Typescript enforcement option.

Greate idea. I am Apex (and VisualForce in old days) developer and for me JavaScript is a nightmare with this freestyle.
I would prefere to write LWC with TypeScript.

@Charles Jonas, as you wisely pointed out in this article, although it's possible to combine TypeScript and Lightning Components, the lack of type definitions and source maps reduces substantially the benefits of going down that path.

Typescript just transpiles down to javascript so it's already possible. https://github.com/ChuckJonas/typescript-belgian-beer-explorer-lightning

In additon to the comments from from the previous commentors, enabling TypeScript would attract more Java and C# developers who normally would refuse to learn JS. It's important to target this pool of developers if Salesforce want the aura framework to be more widely adopted and, as a result, Salesforce migration path from Classic to LE will be faster.

TypeScript being a type safe language, the Lightning component must support TypeScript which eventually compiles to JavaScript. As we find the similarity between the architecture of lightning and angular 2/4, they are component based frameworks, if the Lightning component is TypeScript supported the development time would reduce tremendously due to existing knowledge of OOPS concepts with the developers which can be used in TypeScript easily. Which will also grab attention for many TypeScript developers to work on Force.com platform and contribute to the community.

Typescript compilation would be EXTREMELY beneficial to lightnitng component development. Most lightning component programming errors could be caught at the time of compilation putting it on par with apex development.
