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-lists/flat. Try it out:
const lists = require('extra-lists');
var x = [['ab', 'cde'], [
[['a', 'b'], [1, 2]],
[['c', 'de'], [
3,
[['d', 'e'], [
3,
[['e'], [
5
]]
]]
]]
]];
lists.flat(x).map(c => [...c]);
lists.flat(x, 1).map(c => [...c]);
lists.flat(x, 2).map(c => [...c]);
