Typescript is a superset of JavaScript built-in, adding optional static types and object-oriented programming to help us develop large web applications. Sublime Text is a code editor, with a beautiful user interface and strong plug-in support, through the Sublime to write Typesript can let us go to the duck, Sublime support the build function, can compile some common language, However, the compilation of Typesript to JavaScript cannot be completed. Bu
Introduction:
Typescript, a free and open source programming language developed by Microsoft, is a superset of JavaScript that extends the syntax of JavaScript. Syntax attribute class Classes interface interfaces module Modules type annotation type annotations compile-time type check compile Arrow function (similar to C # Lambda expression) the difference between JavaScript and typescript

Typescript is a hyper-set of JavaScript, which means it supports all JavaScript syntax. It's much like a JavaScript-strong-type version, besides, it has some extended syntax, such as Interface/module.Typescript will remove the type and the unique syntax during compile time, generating pure JavaScript.

We all know that JavaScript is not an object-oriented language, and that JavaScript can handle a variety of requirements when the Web front-end is not very complex before, but when the current development is more and more complex, JavaScript becomes more and more powerless, And Typescript is the language that was born to solve this situation, typescript
Typescript is one of the core design principles is type checking, through the use of interface (interfaces) can be type checking, to meet the traditional object-oriented thinking, conducive to effective development, effectively avoid type conversion problems.
In typescript, interfaces are used as constraints, and when translated into JavaScript, all interfaces are wiped out because JavaScript does not have
TypeScript-Basic Type SystemFor programs, we need basic data units, such as numbers, strings, structures, and boolean. In TypeScript, we support many data type systems that you expect in JavaScript. Boolean also has the most basic logical asserted values true/false in JavaScript and TypeScript, and adopts the 'boolean' type. Var isDone: boolean = false; Number, s

namespaces to avoid conflicts with other types if the type is not used directly or cannot have a unique name. callback function
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
In typescript, interfaces are used as constraints, and when translated into JavaScript, all interfaces are wiped out because JavaScript does not have the concept of interfaces.
Let's take a look at a simple example:
function Printlabel (labelledobj: {label:string}) {
console.log (Labelledobj.label);
}
var myobj = {size:10, Label: "Size Ten Object"};
Printlabel (myobj);
So in this method, the type of Labelledobj is {label:string}, wh

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

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
There are some unique concepts in typescript that need to describe what has changed in the JavaScript object type. For example, the most unique concept is "declaration merging". Understanding this concept will be helpful for you to use typescript development in your current JavaScript project. It also opens the door to understanding more advanced abstract concepts.For the purposes of this article, declarati
In this note, let's take a look at the functions in typescript.function typeThere are two ways to define a function in JavaScript, such as the following:1 // named Functions 2 function Add (x, y) {3 return x+y; 4 }56// anonymous functions 7var function return x+y; };The corresponding wording in typescript is as follows:1 function Add (X:number, Y:number): number {2 return x+y; 3 }45varfunctionreturn x+y; };And
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
