Basic of TypeScript

TypeScript is a syntactic enhancement for JavaScript. The TypeScript syntax is a superset of Ecmascript 5 (ES5) syntax. Every JavaScript program is also a TypeScript program. The TypeScript compiler performs only file-local transformations on TypeScript programs and does not re-order variables declared in TypeScript.

The following example shows the basics of TypeScript programs. The example just prints "Hello" in the HTML document.

Coding

simpledemo.ts

class simpledemo {

constructor(public greeting: string) { }

greet() {

return"<h1>" + this.greeting + "</h1>";

}

};

var simple = new simpledemo("Hello, C-sharpcorner user....!");

var str = simple.greet();

document.body.innerHTML = str;

simpledemo.html

<!DOCTYPEhtml>

<html>

<head><title> TypeScript simpledemo </title></head>

<body>

<scriptsrc="app.js"></script>

</body>

</html>

app.js

var simpledemo = (function () {

function simpledemo(greeting) {

this.greeting = greeting;

}

simpledemo.prototype.greet = function () {

return"<h1>" + this.greeting + "</h1>";

};

return simpledemo;

})();

; ;

var simpledemo = new simpledemo("Hello, C-sharpcorner user...!");

var str = simpledemo.greet();

document.body.innerHTML = str;
