Ezno is work in progress. It doesn't currently support all the features of JavaScript and TypeScript but it has a fairly large specification of features that it supports today. While it isn't worth it trying it on existing codebases ATM as it likely will blow up. You can try out the snippets in the specification and other small pieces of code today.
You can try the check command of ezno using npx
npx ezno check file.tsOr download the binary with npm install ezno, cargo install ezno or on GitHub releases.
You can use the print_type function to see the type of expressions.
const x = 6;
print_type(x + 8)If you find any unexpected exceptions, please leave an issue 😁
