This fork contains a few modifications to Typescript to preview the try-expression-proposal syntax. It is not intended to be used in production.

• Create a new npm project folder using npm init.
• npm install the built tgz file from the releases page of this repository.
  • https://github.com/Arlen22/TypeScript/releases/download/arlen22-dev-0.3/typescript-5.8.0-arlen22-0.3.tgz
• In VSCode, create a new typescript file and open it to enable the Typescript engine, then run the command "Typescript: Select Typescript Version" and select the version from your node_modules folder.
• Create a tsconfig.json file with strictNullChecks enabled.
• If you run tsc it will just pass the syntax through to the Javascript file.

const [error, data]: TryResult<1> = try 1;
if (error) {
  const e: TryError = error;
  const r: undefined = data;
} else {
  const e: undefined = error;
  const r: 1 = data;
}
// try at the beginning of an arrow function body
const [error1, data1] = (() => try someExpression() ?? otherexpression() ? true : false)();
// regular assignment, terminated by comma, semicolon, or other statement.
const [error2, data2] = try someExpression() ?? otherexpression() ? true : false;
// used as an array value, terminated by comma or end of array
const [[error3, data3]] = [try someExpression() ?? otherexpression() ? true : false];
// used as an object value, terminated by comma or end of object
const { res: [error4, data4] } = { res: try someExpression() ?? otherexpression() ? true : false }

• Added the try-expression-proposal syntax to the parser basically copying the yield syntax.

• Failed attempt that only partly worked.

TypeScript is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the playground, and stay up to date via our blog and Twitter account.
