## algorithm codes

### 1. filter items for react apps

 ```js

    const rows = [];

        this.props.products.forEach((product) => {

            if (product.name.toLowerCase().indexOf(filterText.toLowerCase()) === -1) {

                return;

            }

            if (inStockOnly && !product.stocked) {

                return;

            }

            rows.push( );

        });

   ```

### 2. read and write sql db with nodejs

   ```js

   const mysql = require('mysql');

   // Ma'lumotlar bazasiga ulanish uchun konfiguratsiya

    const connection = mysql.createConnection({

      host: 'localhost',

      user: 'your_database_user',

      password: 'your_database_password',

      database: 'your_database_name',

    });

    // Ma'lumotlar bazasiga ulanish

    connection.connect((err) => {

      if (err) {

        console.error('Xatolik yuz berdi: ', err);

        return;

      }

      console.log('Ma\'lumotlar bazasiga muvaffaqiyatli ulanildi!');

    });

    

    // Ma'lumotlar bazasidan so'rov yuborish

    const sqlQuery = 'SELECT * FROM your_table_name';

    connection.query(sqlQuery, (err, result) => {

      if (err) {

        console.error('So\'rov yakunlanishida xatolik: ', err);

        return;

      }

      console.log('Javob: ', result);

    });

    

    // Ulanishni yopish

    connection.end((err) => {

      if (err) {

        console.error('Ulanishni yopishda xatolik: ', err);

        return;

      }

      console.log('Ma\'lumotlar bazasi bilan muvaffaqiyatli ravishda aloqa yopildi!');

    });

    ```
