Basic usageES6 allows you to define functions using the arrows ( => ).var f = v + V;The above arrow functions are equivalent to:var function (v) { return v;};If the arrow function does not require arguments or requires more than one argument, a parenthesis is used to represent the parameter part.var f = () = 5; // equivalent to var function return 5 }; var sum = (NUM1, num2) = Num1 + num2; // equivalent t

Recent projects require the development of a guided view of arrows, where the contents of the view are variable.According to the product requirements, summed up some experience:A product requirement:1 arrows to the horizontal center of the graph to be pointed;2 The boot view is fixed in size, but the position requirement varies according to the position being directed;Second experience:1 calculates the position of the entire graph according to the position pointed by the

This component allows you to draw arrows Based on the coordinate at the start and end of arrows. Currently, you can set the arrow shape (size and angle) for the widget ). Example: Put the following code directly: Arrow. js /*** Implement the function of drawing arrows between two points * @ author mapleque@163.com * @ version 1.0 * @ date 2013.05.23 */; (function (window, document) {if (window. mapleque

Break the arrow-never believe in your own will or become a general In the Spring and Autumn and Warring States Periods, a father and his son fought for war.

C ++ containers store certain data structures for data search or sorting or other special purposes. As we all know, common data structures are similar to arrays.Array, Linked listList, TreeTreeStackStack, QueueQueue, HashHash Table, SetSet, I

This article mainly and we introduce the use of CSS to achieve arbitrary size, any direction and any angle of the arrows examples of relevant information, small series feel very good, and now share to everyone, but also for everyone to do a reference, hope to help everyone. In web development, the drop-down arrows are often used , RIGHT Arrow Such an arrow. CSS is generally used to achieve: { d

The arrow operators are different. It might behave like a two-dollar operator: Accept an object and a member name, and dereference the object to get the member. the arrow operator does not accept explicit parameters, regardless of appearance. There is no second parameter, because the right operand----is not an expression, instead it is an identifier that corresponds to a class member. There is no obvious wa

The ES6 standard adds a new function: arrow function.Why is it called Arrow Function? Because it's defined by an arrow:x = x * xThe above arrow functions are equivalent to:function (x) { return x * x;}The arrow function is equivalent to an anonymous function and simplifies the function definition. The

Point of this in es5 var factory = function(){ this.a = ‘a‘; this.b = ‘b‘; this.c = { a:‘a+‘, b:function(){return this.a} } };console.log(new factory().c.b()); // a+ Through es5 syntax call, the returned result is a +, and this points to the object called by the function, that is, who this points to when the function is called, which object calls this function? Who is this. Point of the arrow function this in es6 var factory =

Vector C ++, VectorVector container typeA vector container is a template class that can store any type of objects (but must be the same class object ).
