The generator (generator) is the new data type introduced by the ES6 standard. A generator looks like a function, but can be returned multiple times.ES6 define the generator standard Buddy borrowed from the Python generator concept and syntax, if you are familiar with Python

First, the basic conceptThe generator function is a function that can pause execution, return a iterator object, yield is a paused identityfunction* gen () { 1; 2; }The generator function has a *, with a yield statement inside it.function* gen () { 1; 2; return ' 1 '= Gen ();//Call the generator function to return the iterator object Console.lo

This article introduces the python iterator and generator in detail. 1. what is an iterator? Let's talk about iteration first. iteration is a process that repeats many times, for example, for loop. The for loop can iterate on all objects with iter methods. what is the iter method? Whether an object can be iterated depends on whether the object has an iter method. when the object's iter method is called, an iterator is returned. this iterator must hav

The generator function is the first available feature in python2.2. It is built in Version 2.3 to support this feature, and yield becomes a keyword, the generator is enhanced in later versions (for example, exception handling is added ). Similar features (iterators) are introduced in C #2.0, which have many similarities. This article discusses ironpython 2.0 beta3. Any function that contains the yield exp

: >>> [x * x for x in range(1, 11) if x % 2 == 0][4, 16, 36, 64, 100] 小结:The use of list generation, can be generated quickly list , can be deduced from one list another list , and the code is very concise. 2. Generator ???? With list generation, we can create a list directly. However, with memory limitations, the list capacity is certainly limited. Also, creating a list of 1 million elements takes up a lot of storage space, and

Iterator, yield expression, generator, coroutine, and iteratorcoroutine in Python Every time I look at the code written by others, I have yield. I feel like a super geek. Today I will spend some time organizing it. In order: 1. iterator Iterator is called an iterator used to traverse serialized data, such as a list or set. If an object wants to be able to be traversed by an iterator, as long as the _ iter _ () method is added to the class of this obje

This article and everyone to share is mainly in JavaScript asynchronous Generator related content, come together to see it, hope to learn JavaScript help you. asynchronous generators and asynchronous Iteration have arrived ! this is wrong. , They're still here . Stage 3 , which means they are very likely to JavaScript will be released in a future version. Before they are released, you can use Babel to work on your project using the recommended cont
