In the configuration item for the Chrome developer tool, there is a sourcemap option to configure the JavaScript source and generate code relationships.If you can debug the typescript code directly in the browser, we can really appreciate the joy of typescript development.First open the Chrome developer tools configuration item, and then look at the Enable Source maps option under Sources,If it is already s

Many JavaScript libraries receive a function as a parameter and then call it by passing in a known parameter. When signing for these types and functions, do not mark this argument as an optional parameter. The right way to think is "what kind of parameters will be provided." ", not" what parameters will be used. ”。 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
Object-oriented programming-declaration and use of classesThe advent of classes allows the front-end programmer to abstract levels, increase maintainability, and reuse. Of course, this series of classes of operations, we call him object-oriented programming. Typescript is a class-based object-oriented programming language.A class is an abstraction of a specific transaction of an object, which is the concret
the front end.(Note: If the first time is an update operation, no data structure, you must first perform a query operation, or you will get an error.) )The data for all operations on the page is cached by the browser and then updated to the database via the SaveChanges method. The parameter "Jobject Savebundle" is a JSON object。 All the structures and data previously obtained through metadata () will be inside. (Pros: Reduce code volume, Cons: Performance is a question.) and of

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
Environment construction
This article will briefly introduce typescript and document the development environment, using visual Studio code for a simple demo development process.
The first part, introductionTypescript is a free and open source programming language developed by Microsoft. is a superset of JavaScript. It adds a number of features of static languages, including but not limited to the following, on the basis of preserving the
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

1. What is typescript.
Typescript is a superset of JS, it adds a static type of support to JS.
Read a paragraph of JS code:
var bill = {
name: "Bill",
Quack:function () {
document.write ("quack!");
}
function Sayquack (target) {
target.quake ();
}
Sayquack (Bill);This code will run wrong because, in Say
For the program we need basic data units, such as: numbers, strings, structures, Boolean and other data structures. In typescript we support many of the data type systems that you expect to have in JavaScript.
Boolean
In JavaScript and typescript, there is also the most basic logical assertion value true/false, using the ' Boolean ' type.
1var Isdone:boolean = false;Number
All numeric types, such as Javascr
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. ’

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 is a JavaScript superset. after TypeScript is compiled, JavaScript code is generated. TypeScript is typed, which is called TypeScript. Compared with weak JavaScript, typed typescripts are easier to maintain. There are 7 basic types in TypeScript.

the reader can organize the code according to his own ideas, thus writing a new game engine. Plus now with the typescript tool, you can intuitively use the "class definition" syntax and provide compile-time type checking and code refactoring to help you write concise code and improve development efficiency.So I used typescript to reorganize and write the sample code in the book, and to add some of my own d
