/** | |
* Creates a `lodash` object which wraps the given value to enable intuitive | |
* method chaining. | |
* | |
* In addition to Lo-Dash methods, wrappers also have the following `Array` methods: | |
* `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`, `splice`, | |
* and `unshift` | |
* | |
* Chaining is supported in custom builds as long as the `value` method is | |
* implicitly or explicitly included in the build. | |
* | |
* The chainable wrapper functions are: | |
* `after`, `assign`, `bind`, `bindAll`, `bindKey`, `chain`, `compact`, | |
* `compose`, `concat`, `countBy`, `create`, `createCallback`, `curry`, | |
* `debounce`, `defaults`, `defer`, `delay`, `difference`, `filter`, `flatten`, | |
* `forEach`, `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, | |
* `functions`, `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, | |
* `invoke`, `keys`, `map`, `max`, `memoize`, `merge`, `min`, `object`, `omit`, | |
* `once`, `pairs`, `partial`, `partialRight`, `pick`, `pluck`, `pull`, `push`, | |
* `range`, `reject`, `remove`, `rest`, `reverse`, `shuffle`, `slice`, `sort`, | |
* `sortBy`, `splice`, `tap`, `throttle`, `times`, `toArray`, `transform`, | |
* `union`, `uniq`, `unshift`, `unzip`, `values`, `where`, `without`, `wrap`, | |
* and `zip` | |
* | |
* The non-chainable wrapper functions are: | |
* `clone`, `cloneDeep`, `contains`, `escape`, `every`, `find`, `findIndex`, | |
* `findKey`, `findLast`, `findLastIndex`, `findLastKey`, `has`, `identity`, | |
* `indexOf`, `isArguments`, `isArray`, `isBoolean`, `isDate`, `isElement`, | |
* `isEmpty`, `isEqual`, `isFinite`, `isFunction`, `isNaN`, `isNull`, `isNumber`, | |
* `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`, `join`, | |
* `lastIndexOf`, `mixin`, `noConflict`, `parseInt`, `pop`, `random`, `reduce`, | |
* `reduceRight`, `result`, `shift`, `size`, `some`, `sortedIndex`, `runInContext`, | |
* `template`, `unescape`, `uniqueId`, and `value` | |
* | |
* The wrapper functions `first` and `last` return wrapped values when `n` is | |
* provided, otherwise they return unwrapped values. | |
* | |

// a transform stream is a readable/writable stream where you do | |
// something with the data. Sometimes it's called a "filter", | |
// but that's not a great name for it, since that implies a thing where | |
// some bits pass through, and others are simply ignored. (That would | |
// be a valid example of a transform, of course.) | |
// | |
// While the output is causally related to the input, it's not a | |
// necessarily symmetric or synchronous transformation. For example, | |
// a zlib stream might take multiple plain-text writes(), and then | |
// emit a single compressed chunk some time in the future. | |
// | |
// Here's how this works: | |
// | |
// The Transform stream has all the aspects of the readable and writable | |
// stream classes. When you write(chunk), that calls _write(chunk,cb) | |
// internally, and returns false if there's a lot of pending writes | |
// buffered up. When you call read(), that calls _read(n) until | |
// there's enough pending readable data buffered up. | |
// | |
// In a transform stream, the written data is placed in a buffer. When | |
// _read(n) is called, it transforms the queued up data, calling the | |
// buffered _write cb's as it consumes chunks. If consuming a single | |
// written chunk would result in multiple output chunks, then the first | |
// outputted bit calls the readcb, and subsequent chunks just go into | |
// the read buffer, and will cause it to emit 'readable' if necessary. | |
// | |
// This way, back-pressure is actually determined by the reading side, | |
// since _read has to be called to start processing a new chunk. However, | |
// a pathological inflate type of transform can cause excessive buffering | |
// here. For example, imagine a stream where every byte of input is | |
// interpreted as an integer from 0-255, and then results in that many | |
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in | |
// 1kb of data being output. In this case, you could write a very small | |
// amount of input, and end up with a very large amount of output. In | |
// such a pathological inflating mechanism, there'd be no way to tell | |
// the system to stop doing the transform. A single 4MB write could | |
// cause the system to run out of memory. | |
// | |
// However, even in such a pathological case, only a single written chunk | |
// would be consumed, and then the rest would wait (un-transformed) until | |
// the results of the previous transformed chunk were consumed. | |
