以下内容主要摘自[1,2] (1)In javascript, functions are first-class objects, which means functions can be used in a first-class manner like objects, since they are in fact objects themselves: They can be “stored in variables, passed as arguments to functions,…
After you understand how C-level extensibility works in Dreamweaver and its dependency on certain data types and functions, it’s useful to know how to build a library and call a function. The following example requires the following five files, locat…
It is said that the one of the most routine work a javascript programmer do is writing codes like "something.onclick= function(e){}". I myself have written thousands lines of codes like this. But one thing I was confused when first coming across…

Azure Functions lets you execute your code in a serverless environment without having to first create a VM or publish a web application. In this article, you learn how to use the Visual Studio 2017 tools for Azure Functions to locally create and test…
Any function can be made asynchronous, including function expressions, arrow functions, and methods. This lesson shows the syntax for each of the function types. For example, we have a demo: const fetch = require('node-fetch'); const BASE_URL = 'http…

A  key part of getting transitions to happen when we want  them to is the design of reasonable cost functions. we want to penalize and reward the right things. I am going to work through an example of  one way you  might think about designing  a cost…
Just like the State ADT an Array is also an Applicative Functor. That means we can do the same tricks with liftA2 with Array that we have been doing with State. While the Applicative aspect of State allows use to combine multiple stateful transitions…
Object.create builds an object that inherits directly from the one passed as its first argument. With constructor functions, the newly created object inherits from the constructor's prototype, e.g.: var o = new SomeConstructor(); In the above example…

function($){}实际上是匿名函数 这就定义了一个匿名函数,参数为arg function(arg){ //code } 而调用函数 时,是在函数后面写上括号和实参的,由于操作符的优先级,函数本身也需要用括号,即: (function(arg){ //code })(param); 这 就相当于定义了一个参数为arg的匿名函数,并且将param作为参数来调用这个匿名函数 而(function($){...}) (jQuery)则是一样的,之所以只在形参使用$,是为了不与其他库冲突,所以实…
