As I was reading the “<a target="_blank" href="https://devblogs.microsoft.com/typescript/announcing-typescript-4-2/">Announcing TypeScript 4.2</a>” post on the TypeScript blog, I discovered a neat feature that is so simple but super valuable to me, so I love to share it here 😁
<h3 id="how-does-it-work">How does it work?</h3>
When you call a function with parameters in a TypeScript file in Visual Studio Code, you get an ugly red line.
If you click the yellow balloon, you can generate a function declaration with typed parameters! <a target="_blank" href="https://github.com/a-tarasyuk">Alexander Trasyk</a> builds this feature 💪.
