  • In JavaScript, when is the target property used in a forEach() loop?

    In JavaScript, the target property is not directly associated with a forEach() loop itself. However, when you’re using forEach() to iterate over a collection of DOM elements (like those obtained from document.querySelectorAll()), you might encounter the target property if you’re working with event listeners inside the loop.

    Here’s an example:

    document.querySelectorAll('.my-button').forEach(button => {
    button.addEventListener('click', (event) => {
        console.log(event.target);  // This will log the button that was clicked
    });
});

    In this case, event.target refers to the element that triggered the event (e.g., the button that was clicked). So, while target isn’t specific to the forEach() loop, you may use it inside the loop when handling events on elements.

  • MySQL CLI Quick Reference

    Connecting to MySQL

    • Login to MySQL:
      mysql -u username -p

    Prompts for a password.

    • Specify Database on Login:
      mysql -u username -p -D database_name

    Basic Commands

    • Show all databases:
      SHOW DATABASES;
    • Select a database:
      USE database_name;
    • Show all tables in the current database:
      SHOW TABLES;
    • Describe the structure of a table:
      DESCRIBE table_name;
    • Show the current MySQL user:
      SELECT USER();
    • Show current database:
      SELECT DATABASE();
    • Show process list:
      SHOW PROCESSLIST;
    • Show full process list (to see full queries):
      SHOW FULL PROCESSLIST;
    • Exit MySQL:
      EXIT;

    CRUD Operations

    • Create a new database:
      CREATE DATABASE database_name;
    • Create a new table:
      CREATE TABLE table_name (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100),
    age INT
  );
    • Insert data into a table:
      INSERT INTO table_name (name, age) VALUES ('John', 30);
    • Select data from a table:
      SELECT * FROM table_name;
    • Update data in a table:
      UPDATE table_name SET age = 31 WHERE name = 'John';
    • Delete data from a table:
      DELETE FROM table_name WHERE name = 'John';
    • Drop a table:
      DROP TABLE table_name;

    Loading .sql Files

    To load and execute an SQL file that contains queries or database structure (e.g., schema.sql or data.sql):

    Method 1: From Inside the MySQL Prompt
    1. Open MySQL:
       mysql -u username -p
    1. Select the database you want to load the file into:
       USE database_name;
    1. Load the SQL file:
       SOURCE /path/to/your/file.sql;
    Method 2: Directly from the Command Line

    You can execute the SQL file directly from the command line without entering the MySQL prompt:

    mysql -u username -p database_name < /path/to/your/file.sql

    This method runs the .sql file directly into the specified database.

    Common Tips

    • View running MySQL queries:
      Use SHOW FULL PROCESSLIST; to view running queries, especially helpful for debugging long-running queries.
    • Check MySQL version:
      SELECT VERSION();
    • Enable SQL logging:
      Use SET GLOBAL general_log = 'ON'; to start logging all queries. To view the log, check the path from the following:
      SHOW VARIABLES LIKE 'general_log_file';

    These commands and tips should help you navigate MySQL efficiently!
