mastering typescript

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 () + "!");

may be more convenient and faster. Why use ES5,ES6,TypeScript to demo ? Let's introduce these three concepts:ES5: Full Name ECMAScript5, which can be understood as our regular JavaScript(in fact JavaScript also contains the DOM and the BOM ), which is currently supported by most browsers JavaScript syntax characteristics, in ES5 before that, there was ES3 . ES6: It is the ECMAScript Language Specification , which expands the new grammatical feature

The previous blog I have written about the development patterns of JavaScript large programs that I have been expecting, along with some advantages of TS (TypeScript). After the blog was completed, I spent another day experimenting with TS, which was used to reconstruct a JS game that I wrote before: "Javascript tank game."

1. What is typescriptTypescript 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-oriented object-oriented programming to the language. Typescript adds support for the features recommended for the upcoming ECMAScript 6 standard.Google's front-end framework angular is based on typescript development. 2.

Inheritance of classes: object-oriented patterns Super: Keywords Class Animal { name:string; Constructor (thename:string) { this.name = thename; } Move (Distanceinmeters:number = 0) { console.log (' ${this.name} moved ${distanceinmeters}m. '); } Class Snack extends Animal { Constructor (name:string) { super (name);//Call constructor of parent class } // Overrides the parent class's method move (Distanceinmeters = 5) { console.log ("slithering ..."); Supe

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

Why?Why use typescript, what are the benefits and when do I need it? Well, Typescript introduction on-line search is a big pile, various explanations, certainly more than I said the details, you can Google yourself. So, let's talk about my personal opinion! 1, out of curiosity about a new language, "black technology" what the total use of the meaning (like bridge.net is the C # version of JavaScript), not t

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

You may be familiar with Mixins and its features in languages like Scala, but it's also popular in JavaScript.Mixed sampleThe following code shows how to use mixed in

In addition to the customary idea of facing objects, another popular way to create classes from reusable components is to mix simple classes together. You may be familiar with this hybrid approach or have an understanding of the features of the Scala language, a pattern that is popular in the JavaScript community.Mixed caseIn the following code, we show how to mix the model in typescript, after reading the code, and then analyzing its execution.//Disp

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
