typescript vs javascript

Generic typeFor C # Programmers, Typescript generics are familiar, basically consistent design.Type constraintsC # uses the WHERE keyword to mark type constraints, and typescript uses the extends keyword within angle brackets for the same effect.In the following example, Iexample constrains the generics to be imyinterface and his derived class.If used like this, it can be constrained to inherit both Classon

. Expansion InterfaceLike classes, interfaces can be extended. Allows you to be more free to make your interfaces reusable components. Interface Shape { color:string; } Interface Square extends Shape { Sidelength:number; } var square = Square.color = "Blue"; Square.sidelength = 10; Copy CodeAn interface can extend multiple interfaces, creating a combination of all interfaces. Interface Shape { color:string; } Inte

3.ts function 1) function of the return value and parameters in the definition of the function needs to define its return value can be void, to represent the definition of a function parameter without a return value, for example to analyze the next name:string,age?:number=23 colon is the type of the parameter, add a? Indicates that this parameter is not mandatory, so you can understand it here. If a parameter is written, then it needs to be added, because it is not necessarily transmitted. Using

C # vs TypeScript-Advanced typeThe previous article said the basic type, basically with the basic type enough to develop, but if you want to develop more efficiently, or to look at the high-level type, this and C # have little in common, just use this topic.Union typeCan literally be understood: is actually multiple types of union together, | separated by symbols.such as: string | number , expressed the hope that this type can be both string , and can

At the Build 2015 conference, Microsoft released the typescript 1.5 Beta with Visual Studio RC, which allows you to learn about Typescript's future development progress. Mi

Tags: oid document RIP Inter book Markdown about fun ASIOverviewThis is my note to study typescript. There are 2 reasons to write this note, one to be familiar with the relevant writing, and the other to clarify some of the obscure things. For future development, I believe it will be useful for other people as well. Learn typescript suggest reading Chinese documents or English documents directly. I am loo

First, prefaceJust last month, a colleague of the company suggested that the current front-end should be used to angularjs for development, and we were using the ASP. NET 5 project, originally my plan is to use typescript direct ANGULAR2 development. So take this time to write about how to build a typescript-based ANGUALR2 project under ASP. NET 5, and let's get to the point.Second, the Environment configur

Referring to the "Rise of Typescript", the article recommended today once again supports this view--xamarin studio also began to support typescript development.One important aspect of whether a language can rise is the support of development tools. Support for Visual Studio is natural, and Microsoft has recently released the Typescript 1.4 Toolkit. Webstorm also

Recently contacted Typescript, feeling very strong, but also have some problems.For example, we normally write JS, as long as the other JS library into the page, and even as long as added to the project, ReSharper will automatically analyze him, and provide grammar can only sense, write code very comfortable.However, since Typescript is a strongly typed language, he does not allow other unknown JS libraries

Modules, types, interfacesTypescript modules are used for code organization, similar to the C # namespace. A module can contain multiple classes and interfaces. Classes and interfaces can be privatized or exported, and the export means public, allowing other modules to access them.Typescript class and C # have the same class meaning. In fact, one of the highlights of typescript is that he hides JavaScript's prototype design, but instead uses a more po

Typescript–interface Concept: Typescript interface defines the type of object (my understanding: Defines the types of object attributes and the public methods in the extraction Class) categories:Optional attributes of an interface: the attributes in an interface are not all necessary, and interfaces with optional attributes are similar to ordinary interfaces, but are added after optional attributes. ’ Optio

Decorators is a feature of TypeScript that is becoming more and more common in many major libraries. This lesson walks-through what decorators is and how to create your own.Nomarl to decorate a object:Const PERSON = {name: ' John '}; function Addage (age) { returnfunction(person) { return { , name:person.name } = addage (person); Console.log (John);//{name: "John", age:30} In

A recent project, the use of typescript to write JS script, the results are riddled with errors, repair also let me summarize the TS in how to use this. TS provides static types similar to C # and Java (strongly typed), declaring a function directly in global and namespace global and using the Functions keyword (which is the function keyword of JS), while in class you cannot use function to declare a method. Let's compare it to the C # difference

ClassIn typescript, a structure similar to C #, where multiple classes can exist in a file, and the filenames can be arbitrarily taken, let's look at a simple example of a class.1 class Person {2 private name:string;3 private age:number;4 5 Public Constructor (name:string, Age:number) {6 This. Name =name;7 This. Age =Age ;8 }9 Ten Public talk () { OneAlert ("Hi, my name is" + This. Name + ", I am" + This. age.tostring () + "!");

In this section, we will describe the type inference in typescript. We will discuss where the type inference needs to be used and how to infer it.BasisIn typescript, type inference is used to provide type information in several places where there are no explicitly specified type annotations.var x = 3;The value of the variable "x" is inferred as number. This inference occurs when a variable or member is init

1, it is optional. That is, it does not let you completely abandon JS, and jump to another completely different language. You can even change the source code file from the JS suffix to the TS suffix to start enjoying the benefits of typescript. 2, compatible with ECMAScript standard. In particular, the latest version of TS is designed to be fully compatible with ES6. The benefit of this is that developers can use TS to advance the new features of ES6

The front end in this direction, the ability to accept new things and speed determines your position in the entire industry. NG2 has not yet released the official stable version, but I think for me this time is the best time to store, so began to ng2 the road of learning. Contact with Ng2 before also contact with a Avalon things, but do not know where the phase grams, is not smooth, and then think, are the same, and learn more reference to the NG2. NG2 support
