In this lesson, we'll look at how we can use Ramda's invoker and constructNfunctions to take methods of an object and turn them into reusable utility functions that are curried and accept their object as the last argument. We'll convert a dot-chained…

The registration of callback functions is very common in JavaScript web programming, for example to attach user interface event handlers (such as onclick), or to provide a function to handle an XHR response. Registering an object method as a callback…

Convert Object to XML using LINQ. Also the object contains other object list. Following is the Classes used in our program: public class Order { public string OrderId { get; set; } public string OrderNumber { get; set; } public string OrderDate { get…

Most of the functions offered by the ramda library are curried by default. Functions you've created or that you've pulled in from another library may not be curried. Ramda's curry and curryN functions allow you to take a non-curried function and use…

最近在看<TensorFlow 实战Google深度学习框架第二版>这本书,测试LeNet-5这个模型时遇到了TypeError: Failed to convert object of type <class 'list'> to Tensor的报错,由于书作者没有给出测试的代码,所以根据前面第五章给出的mnist测试代码修改了测试的代码.至于报错的原因尚且不是很清楚,不过找到了解决方法.只要设置好输入数据X的每个维度大小就可以了.比如 x = tf.placeholder(tf…

In this lesson we'll use a handful of Ramda's utility functions to take a queryString full of name/value pairs and covert it into a JavaScript object so we can access those properties in a more useful way. Along the way, we'll build up a composition…

In this lesson, we'll use Promise.all to get an array that contains the resolved values from multiple promises. Then we'll see how we can use Ramda to convert that array of values into a single object using zip with fromPairs. Then we'll refactor to…

一.Object method context 1.We have seen that adding global functions requires extending the jQuery object with new methods. Adding instance methods is similar, but we instead extend the jQuery.fn object(The jQuery.fn object is an alias to jQuery.proto…

An instance method in Swift is just a type method that takes the instance as an argument and returns a function which will then be applied to the instance. I recently learned about a Swift feature that blew my mind a little. Instance methods are just…

In this lesson we'll take some existing code and refactor it using some functions from the Ramda library, most notably, compose and converge. When we're done, we'll have taken a function with a couple of local variables and parameter references and c…
