In-depth understanding of js generator data types and jsgenerator
1. Overview
Generator is a new data type introduced by ES6. It looks like a function. In addition to return, yield can return multiple times.
Generator is defined by function * (note ),
2. Example
The function cannot save the status, and sometimes the global variable is required to save the number;
2.1
'Use strict '; function next_id () {var id = 1; while (id
2.2 an infinite loop iterator
function* idMaker(){ var index = 0; whi

2. Generational Algorithms. Net divides the memory hosting heap into three generations, Gen 0, Gen 1, Gen 2. If Gen 0 heap memory reaches the threshold, the 0 generation GC is triggered, after 0 generations of GC, the surviving objects in Gen 0 enter Gen1. If

1 Actual instructions for asyncFor a time-consuming process, we give it to someone else (like another thread) to execute, and we continue to work on it, and when someone else takes the time-consuming action and then feeds back the results, that's what we call async.We use an easy-to-understand threading mechanism to implement Asynchrony.2. Principle of the implementation of the co-process notationWhen using a callback function to write an asynchronous program, the code that belongs to an executi
Thrift is an open-source, cross-lingual RPC service framework originally developed by Facebook, which Facebook submitted to the Apache Foundation in 2007. For Facebook at the time, the creation of thrift was designed to address the cross-platform nature of the large data traffic between systems in the Facebook system and the different language environments between the systems.First you need to define the.

is a collector for service-side applications, making full use of multiple CPUs and multi-core environments. So it is a parallel and concurrent collector, and it can establish a predictable pause time model. 7. About GC types.There are only two major types of GC that are accurately classified:Partial GC: The pattern of the entire GC heap is not collectedYoung GC (Minor GC): A GC that collects only young gen (triggered when the Eden area in young

in the function to continuously generate the return value. when xrange (1, 9) is called, a generator object is created. We can modify the foreach line to print the xrange object.
...$xrange_res = xrange(1, 9);var_dump($xrange_res);foreach( $xrange_res as $number){...
Output
We can see that when xrange (1, 9) is executed, a Generator object is indeed returned.Use the send method of the Generator object

Just today we all like the "7 days to learn XX language," such as quick-acting elixir, so I also get a similar name "7 Line code learn Co module" to Bo Eyeball.In order to avoid being dragged out to play small JJ, or first release the so-called 7 lines of code to everyone pressure yajing:function co(
: pipeline (pipeline). Pipelines here are not the same as pipes in a Linux system, and the pipelines here refer to data streams with multi-channel channels that are connected by using the channel to connect multiple processing steps. In general, pipelines read data through an inflow port, send data from a stream exit, and then call certain functions to process the data after reading the data.
Each level in the pipeline can have multiple inflow and flow exits, but the first and last stages of the
next is called, the function is executed to the first yield. Each time a yield statement is run, a value returned as next is obtained. after the yield statement is executed, the function execution is stopped.
