Hey folks, I'm happy to announce that the next iteration version of the TypeScript Website has launched on typescriptlang.org. 

C# 11 is the next version of C# coming in .NET 7, and it is introducing a warning wave that issues a warning when a type is declared with all lower-case letters. This is being done so that in the future the language can begin moving away from conditional keywords and instead use full on keywords instead. The warning is alerting customers to types that may become keywords in future versions.

ReactJS is wildly popular and thus wildly supported. TypeScript is increasingly popular, and thus increasingly supported.

The two together? Not as much. Given that they both change quickly, it's hard to find accurate learning materials.

React+TypeScript, with JetBrains IDEs? That three-part combination is the topic of this series. We'll show a little about a lot. Meaning, the key steps to getting productive, in the IDE, for React projects using TypeScript. Along the way, we'll show test-driven development and emphasize tips and tricks in the IDE.

Coming from high-level programming languages to TypeScript, a mere mortal dev may naively use an enum for a predefined list of numeric or textual values.
