To run this code in VSCode, you'll need to set up a TypeScript project and install the necessary dependencies. Here's a step-by-step guide:
1.Install Node.js: Make sure you have Node.js installed on your system. You can download it from the official website: https://nodejs.org/
2.Install TypeScript: Open a terminal and run the following command to install TypeScript globally:
npm install -g typescript
3.Set up a project folder. Create a new folder for your TypeScript project.
4.Initialize a TypeScript project: Open a terminal in the project folder and run the following command:
tsc --init
This will generate a tsconfig.json file that contains TypeScript compiler options.
5.Install RxJS: In the terminal, navigate to your project folder and run the following command to install the required rxjs package:
npm install rxjs
6.Create a new file: In your project folder, create a new file called example1.ts and copy the TypeScript code into it.
import { Observable } from 'rxjs';
const observable = new Observable((subscriber) => {
subscriber.next(1);
subscriber.next(2);
subscriber.next(3);
setTimeout(() => {
subscriber.next(4);
subscriber.complete();
}, 1000);
});
observable.subscribe({
next: (value) => {
console.log(value); // Print the value to the console
},
complete: () => {
console.log('Observable complete'); // Print a completion message
},
});7.Build the TypeScript code: In the terminal, navigate to your project folder and run the following command to compile the TypeScript code:
tsc
This will generate a JavaScript file (example.js) based on the TypeScript code. 8.To run the application:
node example1.js
