Today we’re excited to announce the release of TypeScript 4.5!

If you’re not yet familiar with TypeScript, it’s a language that builds on JavaScript by adding statically checked types. When you use static types, you can run the TypeScript compiler to check for bugs like typos and mismatches in the shapes of your data, and get handy suggestions. These types don’t change your program, and you can remove them to leave you with clean, readable JavaScript. Going beyond catching bugs in your code, TypeScript also assists you in writing code because types can power useful tooling like auto-complete, go-to-definition, and renaming in your editor! You can read more on our website.

To get started using TypeScript 4.5, you can get it through NuGet, or use npm with the following command:

npm install typescript
