About Typescript:Typescript is a free and open source programming language developed by Microsoft. It is a superset of JavaScript and essentially adds optional static types and class-based object-oriented programming to the language. Typescript extends the syntax of JavaScript, so any existing JavaScript program can work without change in typescript. Typescript i

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

Please note that this article is just my prejudice, and I am trying to understand the rationale for writing JavaScript code with compilers such as Coffeescript or typescript. Statically compiled, strongly typed languages and frameworks, I have these popular, rich backgrounds. My last job was to use typescript because I had to use it. It was a time of unhappiness, and I would leave for it.I am fortunate to h

Files globs would be available in TypeScript 2.0, so on the meantime, we need to use "exclude" and "RootDir" to configure W Hich files to load. This lesson shows how to switch from "files" to "exclude".curently, in Tsconfig.json, we use "files" to tell the main entry file as "Src/main". and import other file into Main.ts. But the problem are if you want add all files manually into "Files" config setting, IDEs cannot give the AutoComplete forThe rest o

From C # to typescript-promise backgroundsI believe that friends who have used JavaScript before have encountered asynchronous callback Hell (callback Hell), n multiple callback nesting not only makes the code read very difficult, maintenance is also very inconvenient.In fact, C # Task before the advent of a similar scenario, the Async Programming mode era, with Action and Func do callbacks are also very popular, but also aware that too many callback

Modules in JavaScriptBefore learning the Typescript module, let's look at how the modules in JavaScript are implemented.Benefits of the moduleFirst of all, we need to understand the benefits of using modules what? Modular, reusable; encapsulating variables and functions; The following example is a module that is implemented using javascript:1 varMyModule =function(name)2 {3 //all defined here are private members.4 varMyName =

As one of the initiatives to improve JavaScript Application Development, Microsoft recently released TypeScript. This new language is a superset of JavaScript specifications. It adds type checks and static code analysis, and generates native JavaScript. These features are intended to enable developers to benefit from the convenience of Type checks, making it easier to expand JavaScript to support large-scale application development. The existing JavaS

There are a total of 7 basic types in typescript. 1. Boolean Copy Code code as follows: var Isdone:boolean = false; 2, Number Represents a number in JavaScript. In JavaScript, either "integer" or "floating-point number" is stored as a double-precision floating-point type. Copy Code code as follows: var height:number = 6; 3, String Represents a string. Like JavaScript, you can use a pair of double

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

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 concrete manifestation of the class.Class specificat
