* and the length of the body being transmitted are equal or not. However, when
* receiving messages, Node.js will automatically reject messages when the`Content-Length` does not match the actual payload size.

* The `readable.read()` method reads data out of the internal buffer and

* the data is returned as a `Buffer` object unless an encoding has been
* specified using the `readable.setEncoding()` method or the stream is operating
* in object mode.
*
* The optional `size` argument specifies a specific number of bytes to read. If`size` bytes are not available to be read, `null` will be returned _unless_the stream has ended, in which
* case all of the data remaining in the internal
* buffer will be returned.
*
* If the `size` argument is not specified, all of the data contained in the
* internal buffer will be returned.
*
* The `size` argument must be less than or equal to 1 GiB.
*
* The `readable.read()` method should only be called on `Readable` streams
* operating in paused mode. In flowing mode, `readable.read()` is called
* automatically until the internal buffer is fully drained.
*
* ```js
* const readable = getReadableStreamSomehow();
*
* // 'readable' may be triggered multiple times as data is buffered in
* readable.on('readable', () => {
* let chunk;
* console.log('Stream is readable (new data received in buffer)');
* // Use a loop to make sure we read all currently available data
* while (null !== (chunk = readable.read())) {
* console.log(`Read ${chunk.length} bytes of data...`);
* }
* });
*
* // 'end' will be triggered once when there is no more data available
* readable.on('end', () => {
* console.log('Reached end of stream.');
* });
* ```
*
* Each call to `readable.read()` returns a chunk of data, or `null`. The chunks
* are not concatenated. A `while` loop is necessary to consume all data
* currently in the buffer. When reading a large file `.read()` may return `null`,
* having consumed all buffered content so far, but there is still more data to
* come not yet buffered. In this case a new `'readable'` event will be emitted
* when there is more data in the buffer. Finally the `'end'` event will be
* emitted when there is no more data to come.
*
* Therefore to read a file's whole contents from a `readable`, it is necessary
* to collect chunks across multiple `'readable'` events:
*
* ```js
* const chunks = [];
*
* readable.on('readable', () => {
* let chunk;
* while (null !== (chunk = readable.read())) {
* chunks.push(chunk);
* }
* });
*
* readable.on('end', () => {
* const content = chunks.join('');
* });
* ```
*
* A `Readable` stream in ob |
ject mode will always return a single item from
* a call to `readable.read(size)`, regardless of the value of the`size` argument.
*
* If the `readable.read()` method returns a chunk of data, a `'data'` event will
* also be emitted.
*
* Calling {@link read} after the `'end'` event has
* been emitted will return `null`. No runtime error will be raised.
* @since v0.9.4

*
* The `stream.unshift(chunk)` method cannot be called after the `'end'` event

*
* The return value is `true` if the internal buffer is less than the`highWaterMark` configured when the stream was created after admitting `chunk`.
* If `false` is returned, further attempts to write data to the stream should
* stop until the `'drain'` event is emitted.
*
* While a stream is not draining, calls to `write()` will buffer `chunk`, and
* return false. Once all currently buffered chunks are drained (accepted for
* delivery by the operating system), the `'drain'` event will be emitted.
* Once `write()` returns false, do not write more chunks
* until the `'drain'` event is emitted. While calling `write()` on a stream that
* is not draining is allowed, Node.js will buffer all written chunks until
* maximum memory usage occurs, at which point it will abort unconditionally.
* Even before it aborts, high memory usage will cause poor garbage collector
* performance and high RSS (which is not typically released back to the system,
* even after the memory is no longer required). Since TCP sockets may never
* drain if the remote peer does not read the data, writing a socket that is
* not draining may lead to a remotely exploitable vulnerability.

* problematic for a `Transform`, because the `Transform` streams are paused
* by default until they are piped or a `'data'` or `'readable'` event handler
* is added.
*
* If the data to be written can be generated or fetched on demand, it is
* recommended to encapsulate the logic into a `Readable` and use {@link pipe}. However, if calling `write()` is preferred, it is
* possible to respect backpressure and avoid memory issues using the `'drain'` event:
*
* ```js
* function write(data, cb) {
* if (!stream.write(data)) {
* stream.once('drain', cb);
* } else {
* process.nextTick(cb);
* }
* }
*
* // Wait for cb to be called before doing any other write.
* write('hello', () => {
* console.log('Write completed, do more writes now.');
* });
* ```
*
* A `Writable` stream in object mode will always ignore the `encoding` argument.
* @since v0.9.4
* @param chunk Optional data to write. For streams not operating in object mode, `chunk` must be a string, `Buffer` or `Uint8Array`. For object mode streams, `chunk` may be any
* JavaScript value other than `null`.
* @param [encoding='utf8'] The encoding, if `chunk` is a string.
* @param callback Callback for when this chunk of data is flushed.

* const { pipeline } = require('node:stream');
*
* const server = http.createServer((req, res) => {

*
* If specified, `message` will be appended to the message provided by the`AssertionError` if the `fn` call fails to throw or in case the error validation
* fails.
*
* Custom validation object/error instance:
*
* ```js

* err.foo = 'bar';

* // The `name` and `message` properties are strings and using regular
* // expressions on those will match against the string. If they fail, an
* // error is thrown.
* name: /^TypeError$/,

* // It is not possible to use regular expressions for nested properties!

* // The `reg` property contains a regular expression and only if the

*

*
* ```js
* import assert from 'node:assert/strict';

* },

* );
* ```
*
* Validate error message using [`RegExp`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions):
*

*
* ```js
* import assert from 'node: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 'node: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 'node:assert/strict';
*
* function throwingFirst() {

* }
*
* function throwingSecond() {

*
* // 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');

* // If it was intended to match for the error message do this instead:

*
* // If the error message does not match, an AssertionError is thrown.

* rejected `Promise` with an `ERR_INVALID_RETURN_VALUE` error. In both cases
* the error handler is skipped.
*
* Using `assert.doesNotReject()` is actually not useful because there is little
* benefit in catching a rejection and then rejecting it again. Instead, consider
* adding a comment next to the specific code path that should not reject and keep
* error messages as expressive as possible.
*
* If specified, `error` can be a [`Class`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes),
* [`RegExp`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions), or a validation
* function. See {@link throws} for more details.
*
* Besides the async nature to await the completion behaves identically to {@link doesNotThrow}.
*
* ```js
* import assert from 'node:assert/strict';
*
* await assert.doesNotReject(
* async () => {
* throw new TypeError('Wrong value');
