*
* ```js
* import assert from 'assert/strict';
*
* assert.throws(
* () => {
* throw new Error('Wrong value');
* },
* Error
* );
* ```
*
* Validate error message using [`RegExp`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions):
*
* Using a regular expression runs `.toString` on the error object, and will
* therefore also include the error name.
*
* ```js
* import assert from 'assert/strict';
*
* assert.throws(
* () => {
* throw new Error('Wrong value');
* },
* /^Error: Wrong value$/
* );
* ```
*
* Custom error validation:
*
* The function must return `true` to indicate all internal validations passed.
* It will otherwise fail with an `AssertionError`.
*
* ```js
* import assert from 'assert/strict';
*
* assert.throws(
* () => {
* throw new Error('Wrong value');
* },
* (err) => {
* assert(err instanceof Error);
* assert(/value/.test(err));
* // Avoid returning anything from validation functions besides `true`.
* // Otherwise, it's not clear what part of the validation failed. Instead,
* // throw an error about the specific validation that failed (as done in this
* // example) and add as much helpful debugging information to that error as
* // possible.
* return true;
* },
* 'unexpected error'
* );
* ```
*
* `error` cannot be a string. If a string is provided as the second
* argument, then `error` is assumed to be omitted and the string will be used for`message` instead. This can lead to easy-to-miss mistakes. Using the same
* message as the thrown error message is going to result in an`ERR_AMBIGUOUS_ARGUMENT` error. Please read the example below carefully if using
* a string as the second argument gets considered:
*
* ```js
* import assert from 'assert/strict';
*
* function throwingFirst() {
* throw new Error('First');
* }
*
* function throwingSecond() {
* throw new Error('Second');
* }
*
* function notThrowing() {}
*
* // The second argument is a string and the input function threw an Error.
* // The first case will not throw as it does not match for the error message
* // thrown by the input function!
* assert.throws(throwingFirst, 'Second');
* // In the next example the message has no benefit over the message from the
* // error and since it is not clear if the user intended to actually match
* // against the error message, Node.js throws an `ERR_AMBIGUOUS_ARGUMENT` error.
* assert.throws(throwingSecond, 'Second');
* // TypeError [ERR_AMBIGUOUS_ARGUMENT]
*
* // The string is only used (as message) in case the function does not throw:
* assert.throws(notThrowing, 'Second');
* // AssertionError [ERR_ASSERTION]: Missing expected exception: Second
*
* // If it was intended to match for the error message do this instead:
* // It does not throw because the error messages match.
* assert.throws(throwingSecond, /Second$/);
*
* // If the error message does not match, an AssertionError is thrown.
* assert.throws(throwingFirst, /Second$/);
* // AssertionError [ERR_ASSERTION]
* ```
*
* Due to the confusing error-prone notation, avoid a string as the second
* argument.

# undici-types
This package is a dual-publish of the [undici](https://www.npmjs.com/package/undici) library types. The `undici` package **still contains types**. This package is for users who _only_ need undici types (such as for `@types/node`). It is published alongside every release of `undici`, so you can always use the same version.
