RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including @asoftwareworld/card-validator. Try it out:
@asoftwareworld/card-validator lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:
require("@angular/common/package.json"); // @angular/common is a peer dependency.
require("@angular/core/package.json"); // @angular/core is a peer dependency.
// require("@asoftwareworld/card-validator/[??]")
- all documents on RunKit are public
require()any package directly from npm- use arrow functions, classes, template strings, and most of ES6
awaitany promise instead of using callbacks (example)- create your own embedded node.js snippets
