Installation

To install the package, run:

npm i try-to-js

Examples

Without using try-to-js

import { tryTo } from "try-to-js";

function withoutUsingTryTo() {
  let res: ReturnType<typeof syncFunctionThatCanThrowError> | undefined;
  try {
    res = syncFunctionThatCanThrowError();
  } catch (err) {
    console.log(err);
    return;
  }
  // do something with res
}

Using try-to-js

import { tryTo } from "try-to-js";

function usingTryTo() {
  const [err, res] = tryTo(syncFunctionThatCanThrowError);
  if (err) {
    console.log(err);
    return;
  }
  // do something with res
}

Notes

• If no error is thrown, the err value will be undefined, and res will hold the returned value of syncFunctionThatCanThrowError().
• If an error is thrown, the err value will contain the error that was thrown, and res will be undefined.
