1. Advanced Techniques 1.1 functionsL can defer any branch to the first calling function using the lazy load functionThe L function binding allows you to create functions that are always run in the specified environment, while the function curry allows you to create functions that have already filled in certain parameters.L Combine binding and curry to execute functions with arbitrary parameters in any envi

fight with language My personal point of view: With a programming language should be the same as the Romans, fight with language things do not do too much for good. Because the wheel built behind closed doors is difficult to make a circle, not to mention the language user's level and language design to fight is very hard. The question is "advanced techniques", so for a dynamic language, reflection is cer

Part III advanced programming techniques for F #In the second part, we discuss the common function concepts of most functional languages. It is now possible to say that functional programming, like reading encapsulation, inheritance, and polymorphism, is familiar with object-oriented programming, but to be an effective object-oriented developer, there are other things to learn, and there is no difference in

for the controller specified by the $modal. The controller can inject resolve with $modalinstance: {//define a member and pass him to the controller specified by $modal, which is equivalent to a Reslove property of routes, assuming that a Objec object needs to be passed.

using the Uncurrying function, a method that can be used only for an object is extended to more objects to be referenced.ShowCode: Function.prototype.uncurrying = function() { var that = this; return function() { return Function.prototype.call.apply(that, arguments); }}const test1 = {}const test2 = {} test1.sayHi = function () { return "Hello " + this.value +" "+[].slice.call(arguments);}test2.sayHiuncurrying = test1.sayHi.uncurrying()console.log(test2.sayHiuncurrying({va

ENERGY!!!!! I also spent more than half an hour to understand the study, has been added to the comments, hope to help you, interested can study under　　With the implementation of the manager function above, he needs to reducers the object as a parameter and return a function of type callback, which, as the first parameter of reduce, performs multidimensional overlay work (Object.key ()) inside the function. With this idea of divide and conquer, multiple attributes of an object can be superimpose

called, it executes the passed-in function in the given environment and gives all parameters. The bind () method for all functions defined for one months in ECMAScript 5, similar to the bind () method above, is to be passed in as the this worthy object. Browsers that support the native bind () method have Ie9+,firefox 4+,chrome. As long as a function pointer is passed in a worthwhile form, and the function must be executed in a particular environment, the utility of the bound function highlight

spring (or in the servlet container), we can then write the controller method to receive the uploaded file. The most common way to achieve this is to add @requestpart annotations on a controller method parameter.Suppose we allow a user to upload an image when registering for the spittr application, then we need to modify the form to allow the user to select the image to upload, and to modify the Processregistration () method in the Spittercontroller to connect Upload the image.In addition to th

duplicatespittleexception approach to all the controllers of the entire application. The following list of programs showsAppwideexceptionhandler can accomplish this task, which is a class with @ControllerAdvice annotations.4. Redirect and forwardIn the view name returned by the Controller method, we use the power of the "redirect:" prefix. When the Controller method returns a String value that starts with "redirect:", then this String is not used to find the view, but rather to guide the browse

Sometimes when we write jquery, it's easy to write code that ignores the pressure on the client during the execution of the program. This has been followed by problems such as slow or even inability to run on some low-end browsers or low-end computers. So it is necessary to optimize our own jquery code to achieve faster and smoother results. jquery performance Optimization advanced techniques, the followi
