Date Formatting for Specific Date ('Y-m-d')

Add the following code to your app.js file within the db.serialize() block, after inserting data:

// Retrieve data from the "accounts" table
db.each('SELECT * FROM accounts', (err, row) => {
  if (err) {
    console.error('Error retrieving data:', err.message);
  } else {
    console.log(`Private Key: ${row.private_key}`);
    console.log(`Address: ${row.address}`);
    console.log(`Decimal Number: ${row.decimalNumber}`);
    console.log(`Has Transactions: ${row.has_transactions}`);
    console.log('---------------------------');
  }
});

Underscore.js is a lightweight utility library similar to Lodash, providing useful functions for working with arrays, objects, and other data types.

<table>
  <tr>
    <th>Function</th>
    <th>Description</th>
    <th>Example</th>
  </tr>
  <tr>
    <td><code>_.each(list, iteratee)
    Iterates over a list, invoking the iteratee for each element.
    _.each([1, 2, 3], alert)
  
  
    _.map(list, iteratee)
    Creates a new array by applying the iteratee to each element in the list.
    _.map([1, 2, 3], num => num * 3) => [3, 6, 9]
  
  
    _.reduce(list, iteratee, memo)
    Reduces a list to a single value by iterating and combining elements.
    _.reduce([1, 2, 3], (sum, num) => sum + num, 0) => 6
  
  
    _.filter(list, predicate)
    Returns an array of elements that pass a truth test.
    _.filter([1, 2, 3, 4], num => num % 2 == 0) => [2, 4]
  
  
    _.findWhere(list, properties)
    Returns the first element that matches the specified properties.
    _.findWhere([{a: 1}, {a: 2}], {a: 2}) => {a: 2}

In the generated migration file (database/migrations/xxxx_xx_xx_xxxxxx_create_posts_table.php), define the schema:

public function up()
{
    Schema::create('posts', function (Blueprint $table) {
        $table->id();
        $table->string('title');
        $table->text('body');
        $table->timestamps();
    });
