This article will briefly introduce several basic types of typescript. There are several basic types of typescript: Boolean Number String Array Tuple Enum Any There is also a void type, which is primarily used to identify the type of the method return value.Here are some simple examples to illustrate the basic usage of these types1 //

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

This article describes how to define and use methods in Typescript. I. Method standard declaration and use1 // Method Declaration 2 function func (X:number, Y:number): number {3 return x + y; 4 }In Typescript, a method declaration can clearly define the type of each parameter, and the type of the return value. At compile time, the compiler checks whether the return value type of the method body con

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 () + "!");

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.

JavaScript is the typescript code that is available. Exceptions: the WITH () function and the const keyword for firefox. Variable types cannot be changed dynamically Variables that do not use VAR in the variable JS are global variables TS inside this will be an error. TS Global variables need to declare var myvar = 0 at the highest level of the program; Type TS has optional type detection: main type, array, enum, type strong Interface TS int

Forced type conversions for typescript Converting a number to a string in typescript will cause an error: var a:number = 12345;var b:string = Laygroundsingle.ts (24,18): Error ts2352:neither type ' number ' nor type ' string ' is assignable to the other. This writing is not an error, but there are no eggs to use: var a:number = 12345;var b:string = Console.log (typeof B)"Number" playgroundsingle.js:19:1

First come to know Babylonjs, because based on WEBGL to develop, so first introduce the basic knowledge.WebGL is an HTML standard that he wants to initialize on a canvas element.Preparing for the HTML pageSo let's start by looking at the HTML pageWe set up a canvas that is available for Babylon renderingAnd then because we use typescript, you can see that the script introduced is called App.js, but in my project only app.tsApp.ts will be compiled as a

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

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

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
