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 @extra-entries/has-entry. Try it out:
const entries = require("extra-entries");
var x = [["a", 1], ["b", 2], ["c", -3]];
entries.hasEntry(x, ["c", 3]);
entries.hasEntry(x, ["c", 3], (a, b) => Math.abs(a) - Math.abs(b));
entries.hasEntry(x, ["c", 3], null, v => Math.abs(v));
- 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
