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 @kingjs/linq.element-at-or-undefined with all npm packages installed. Try it out:

var linqElementAtOrUndefined = require("@kingjs/linq.element-at-or-undefined")

all documents on RunKit are public
require() any package directly from npm
use arrow functions, classes, template strings, and most of ES6
await any promise instead of using callbacks (example)
create your own embedded node.js snippets
