ramda vs lodash

arrayelements = [].slice.call (elements);//Now The nodelist are an array Shuffle of array elements For the shuffle of array elements, you do not need to use any external libraries, such as Lodash, as long as you do this: var list = [1,2,3]; Console.log (List.sort (function () {math.random ()-0.5})); [2,1,3] Summarize Now you've learned some useful JavaScript tips. Hopefully these tips will help you solve some of the problems at

. In other environments, we have two choices: 1. Using Third-party libraries, such as underscore or lodash, they all provide a considerable number of common methods for manipulating objects and collections. 2. Define yourself as needed. For example, the following method is defined to get some of the preceding elements in the collection based on a condition: function TakeWhile (A, pred) { var result = []; for (var i = 0, n = a.length i

definition. The factorial (1) In special cases terminates recursion. var imperativefactorial = function (n) { if (n = = 1) {return 1 } else { product = 1; for (i = 1; I } } From the point of view of factorial calculation, the factorial of a declarative may look like a "command", but its structure is more like a declarative type.Imperative factorial uses variable values, loop counters, and results to accumulate the computed results. This method explicitly implement

property descriptor (value, writable, configurable, and so on). var o = object.create ({}, {p: {value:42}}); var O = Object.create ({}, {p: {value:66, Writable:true, Enumerable:true}}); Console.log (O.P); Console.log (O.P);//66 O.P =; O.P =; Console.log (O.P); Console.log (O.P);//80 Property descriptor writable defaults to False, So O.P even after the later assignment can not change its value, and O.P can later change the value, in addition, the Create method proto must pass the co

In the previous chapter, we explained the CreateStore. Next, let's take a look at combinereducer.In Redux, we prohibit the creation of more than one store in the application (we are discussing the client application by default, and the homogeneous application does not apply to this rule). However, as applications become more complex, reducer functions need to be split, and each piece of split is independently responsible for managing part of the state. Combinereducer is to combine a number of re

So far, we have manually introduced all of the resources in the index.html file, but as the application grows, and once the file name is started with hash (hash)] and multiple bundles are output, it becomes difficult to manage the index.html files manually. However, some plugins can make the process easier to manipulate. According to Webpack3 Learning to manage resources, we will have a small project. But in order to facilitate learning webpack management output, here will use WEBPACK3 learning
