Using typescript to develop JS code to improve code maintainability

function test () {     var gs = new Greeter (' SS ');    Alert (Gs.greet ());} Window.onload = Test;class Greeter {    greeting:string;    Constructor (message:string) {        this.greeting = message;    }    Greet () {        return "Hello," + this.greeting;    }}

Because JSON serialization interaction is often used in the background and foreground, it can be very handy if the background-defined model can be used in the foreground, and smart hints and type checking are also very good features.

In the duplicated component, modularity needs to be constantly changing today maintainability is important and useful

Let's look at the JS that it generates

function test () {    var gs = new Greeter (' SS ');    Alert (Gs.greet ());} Window.onload = Test;var Greeter = (function () {    //constructor function function    Greeter (message) {        this.greeting = message;    }    Greeter.prototype.greet = function () {        return "Hello," + this.greeting;    };    return Greeter;} ());//# Sourcemappingurl=file1.js.map

　　

Type check variable check smart hints
