2017-03-29T06:45:34+00:00

An Interface is a description that defines specific methods that implements a class. Again, open your integrated terminal then type ng g interface <interfaceName> An Interface named Security is generated and ready for editing. A sample interface export interface Security { trade(); fairValueCompute(); } To use your interface, first you have to choose a class that will implement your interface. Let’s choose Bonds which we created earlier.   import {Security} from './security'; export class Bonds{ constructor(){ } getBonds(){ } } Import our interface named Security import {Security} from './security'; export class Bonds implements Security{ constructor() In the export class of Bonds, [...]

TypeScript Classes [Typescript Tutorial]

The following is a simple TypeScript class defined. With TypeScript, unlike native JavaScript, there is a native class keyword. The following snippet illustrates a simple TypesScript class definition: class Person { fullname : string; constructor(public firstname, public middleinitial, public lastname) { this.fullname = firstname + " " + middleinitial + " " + lastname; } } Unlike the native JavaScript, TypeScript has a native class keyword. A public member, fullname and a public constructor that acquire three arguments: first, middle and last name.

Your First TypeScript File [Typescript Tutorial]

2017-03-09T07:59:08+00:00

TypeScript requires extensions for its files. It uses either “.ts” or “.d.ts” // setBackgroundColor.ts. function setBackgroundColor() {     document.body.style.backgroundColor = "rgb(255,0,0)"; }     setBackgroundColor(); You might notice that it’s very similar to JavaScript. That’s because it is. Remember TypeScript is a superset of JavaScript. Pure JavaScript and the features of TypeScript that are declarative can be used. In the example, you can see the file is named as setBackgroundColor.ts Next, the image shows how TypeScript files compile resulting in a JavaScript file with the same name. These files are compiled from command line using tsc command. Here the .ts and .js are [...]

From the word from it’s name Type, it associates solid typed layer in synergy with JavaScript. It supports object-oriented programming layer unlike with JavaScript. What differs JavaScript? JavaScript’s nature is known to be functional rather than strongly typed or object-oriented. For most of programmers that are used with defining interface and classes, declaring integers, string or other variables, they might have some difficulty adjusting. In JavaScript, enforcing those integrities can be challenging enough. But you could always declare objects through prototyping. However, [...]
