      message: 'RandomMatrix',
      selector: '[data-randrix]',
      width: 6,

Multiple

Promise

Async, await example. Resolve the promise with the Randrix callback option.

import Randrix from 'randrix';

async function f() {
  const promise = new Promise((resolve, reject) => {
    const randrix = new Randrix({
      message: 'RandomMatrix',
      selector: '[data-randrix]',
      callback: () => resolve(true),
    });
    randrix.start();
  });

  const result = await promise;
  if (result) second();
}

function second() {
  document.querySelector('[data-randrix]').innerHTML = '';
  const randrix = new Randrix({
    message: 'randrix.js',
    selector: '[data-randrix]',
    possible: 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.',
  });
  randrix.start();
}

f();

Generator

Generator, yield example. Go to next() with the Randrix callback option.

import Randrix from 'randrix';

function* panels(configs) {
  for (let i = 0; i < configs.length; i++) {
    yield panel(configs[i], i);
  }
}

function panel(config, i) {
  const wait = (i === 0) ? i : 3000;
  setTimeout( () => {
    document.querySelector('[data-randrix]').innerHTML = '';
    const matrix = new Randrix(config);
    matrix.start();
  }, wait);
}

const configs = [{
    message: 'Random',
    width: 4,
    height: 5,
    callback: () => matrix.next(),
  },
  {
    message: 'Matrix',
    width: 4,
    height: 5,
    callback: () => matrix.next(),
  },
  {
    message: 'Panel',
    width: 4,
    height: 5,
    callback: () => matrix.next(),
  },
  {
    message: 'randrix.js',
    width: 4,
    height: 5,
    possible: 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.',
  },
];
const matrix = panels(configs);
matrix.next();
