This JavaScript code initializes asynchronous execution using the $.async() function and then runs a series of Selenium tasks, specifically logging into Facebook and liking all Facebook posts. The code handles task results by extracting functions from the result object and calling them, and also handles errors by sending them to an unknown object $..

Cell 1

var importer = require('../Core');
var runSeleniumCell = importer.import("selenium cell");

$.async();
var loginFacebook, likeAllPosts;
runSeleniumCell([
    'log in facebook',
    'like all facebook posts',
])
    .then(r => {
        ({
            loginFacebook,
            likeAllPosts,
        } = r);
        return likeAllPosts('https://www.facebook.com/megamindbc', true);
    })
    .then(r => $.sendResult(r))
    .catch(e => $.sendError(e))

// Import necessary modules
const { runSeleniumCell } = require('../Core');
const $ = require('./utils'); // Assuming $ is a utility library

/**
 * Function to perform login and like all posts on Facebook
 * @param {string} url - Facebook profile URL
 * @param {boolean} likeAll - Whether to like all posts
 * @returns {Promise} - Promise resolving with the result of the action
 */
function performFacebookActions(url, likeAll) {
    return runSeleniumCell(['log in facebook', 'like all facebook posts'])
       .then(({ loginFacebook, likeAllPosts }) => {
            return likeAllPosts(url, likeAll);
        });
}

// Perform asynchronous operation
$.async()
   .then(() => performFacebookActions('https://www.facebook.com/megamindbc', true))
   .then(r => $.sendResult(r))
   .catch(e => $.sendError(e));

Code Breakdown

Importing Modules

var importer = require('../Core');
var runSeleniumCell = importer.import('selenium cell');

• The code imports a module named Core from the parent directory (../Core).
• It then imports a function named selenium cell from the imported Core module and assigns it to a variable named runSeleniumCell.

Initializing Async Execution

$.async();

• The code calls a function named async on an object $.
• The purpose of this function call is not explicitly stated in the given code, so it's assumed to be some form of asynchronous execution initialization.

Running Selenium Tasks

runSeleniumCell([
    'log in facebook',
    'like all facebook posts',
])

• The code calls the runSeleniumCell function with an array of two tasks:
  • log in facebook
  • like all facebook posts

Handling Task Results

.then(r => {
    ({
        loginFacebook,
        likeAllPosts,
    } = r);
    return likeAllPosts('https://www.facebook.com/megamindbc', true);
})

• The code uses the then method to handle the result of the tasks executed by runSeleniumCell.
• It extracts two functions, loginFacebook and likeAllPosts, from the result object r.
• It then calls the likeAllPosts function with two arguments: 'https://www.facebook.com/megamindbc' and true.

Handling Result and Error

.then(r => $.sendResult(r))
.catch(e => $.sendError(e))

• The code uses the then method to handle the result of the likeAllPosts function call.
• It sends the result to an unknown object $. using the sendResult function.
• If an error occurs, the catch method is called to handle the error.
• The error is sent to the unknown object $. using the sendError function.
