Learn MoreCreating bicycles in programming refers to the redundant solution of problems that already have effective and proven implementation methods. This can manifest itself, for example, in the development of websites using clean code without the use of modern frameworks. This approach can complicate development and increase project completion time, as there are often many ready-made solutions optimized for various tasks. Using frameworks can significantly simplify the development process, increase its efficiency, and reduce the likelihood of errors.
Many people perceive this activity as inefficient. It takes up time that could be spent on more meaningful activities, while completing already completed tasks seems more productive. However, it is important to consider that such actions can contribute to skill development and increased efficiency in the future.
I disagree with this opinion, as the problem can often be solved using more effective methods. It is important to consider alternative approaches and analyze the situation to find the optimal solution.
It is important to note that this information is relevant to your personal projects or those cases when you are developing code yourself. When working in a team, it's recommended to use predefined tools to help ensure efficiency and consistency in the development process.
The dangers of giving up the wheel
JavaScript developers prefer ready-made solutions because they actively use frameworks and libraries. This allows them to significantly speed up the development process and improve the quality of the applications they create. Using popular tools such as React, Angular, and Vue.js makes it easy to integrate complex features and optimize code. Ready-made solutions help developers focus on solving business problems rather than routine processes.
Some developers prefer to identify themselves not simply as JavaScript developers, but rather specify their skills, calling themselves React, Angular, or Vue developers. This is entirely justified, as it makes it easier for employers to find specialists familiar with the technologies used in their projects. However, such a narrow specialization can become the first problem for developers.

Superficial knowledge
Many developers working with frameworks often have limited knowledge of the programming language itself and its internal structure. In particular, many JavaScript developers are intimidated by the DOM (Document Object Model). They don't understand what it is or what role it plays in development. However, working with the DOM is a key aspect of JavaScript, as it allows developers to interact with HTML elements on a web page. Understanding the principles of the DOM allows you to create more dynamic and interactive web applications.
JavaScript was one of the first programming languages I learned. At the time, I found it quite complex, unlike jQuery, which I mastered quickly and without much difficulty. I was able to understand this framework without a deep knowledge of JavaScript, because jQuery provided convenient tools for accomplishing tasks, and I successfully completed projects without having to delve into the language itself.
An example related to PHP demonstrates the importance of choosing the right tools in development. I was faced with the need to improve a project created by another developer who was using a library for working with databases. This circumstance required me to conduct an in-depth analysis of the project's code and structure to ensure its further support and development. Choosing the right database library is critical to optimizing performance and ensuring application reliability.
The library's author promised simple and secure querying. However, after studying the documentation, I came to the conclusion that in practice, everything is much more complicated. The documentation contains many methods with unclear names, which makes it difficult to understand their functionality. In addition, the placeholder system appears confusing and inconvenient to use. This creates the impression that the library is not as easy to learn as claimed.
PHP has built-in functionality that ensures simple and secure work with databases - this is PDO (PHP Data Objects). If the previous developer or the library author had taken this into account, I would not have had to face difficulties. Using PDO allows you to avoid many common security-related mistakes, such as SQL injection, and simplifies the process of working with different types of databases.
In web development, working with databases is an integral part of the process. I created my library on top of PDO, which allowed me to deepen my knowledge of database structure and query execution mechanisms. This solution not only meets my requirements but also integrates perfectly into my projects, providing convenience and efficiency in working with data.
This is a static method that processes a request and an array of parameters. Depending on the type of request, it returns either an array of rows from the table, or the number of the inserted row, or a Boolean value. This approach allows for flexible data management and provides a convenient interface for working with the database.
Reviewing this text, I realize that it is far from perfect. Nevertheless, the process of writing it was a valuable experience for me. Moreover, it significantly accelerated my work on projects when I was still using PHP.
These days, when I need to solve a small problem, I prefer to develop my own solutions using the capabilities of the programming language. This allows me not only to effectively cope with the problem but also to deepen my knowledge and skills in this area. Creating custom algorithms and functions helps you better understand the language's features and expand its functionality.
Poor optimization
Many frameworks and libraries, such as jQuery, can slow down a website and increase server load. Web page development often requires incorporating numerous scripts, which leads to poor performance and cluttered code. This can negatively impact user experience and page load times. It's important to balance functionality and optimization by selecting only the necessary libraries and minimizing their use. Effective development practices, such as using native JavaScript and minimizing third-party dependencies, can improve loading speed and overall website performance.

Developers strive to create libraries with maximum functionality, but many users do not use all the available features. This results in a significant portion of the capabilities remaining untapped. It's important to understand that usability and ease of use should be a primary focus when developing libraries to make it easier for users to find and use the features they need.
If you use jQuery, you likely need features like AJAX, methods for modifying content, classes, and styles, and selectors. These are just a few of the capabilities jQuery offers. This powerful tool provides a wide range of features to simplify working with HTML documents, event handling, and animation. Using jQuery, you can significantly speed up web application development and improve the user experience on your site.
The user's browser loads large, unnecessary scripts, which increases RAM usage and page load time. This negatively impacts website speed and user experience. Optimizing scripts and removing unnecessary elements will help improve performance and reduce load times.
Optimize your website by avoiding redundant solutions and unnecessary code. By creating your own scripts, you will not only reduce the size of downloaded files but also gain complete control over functionality. This allows you to use only those solutions that are truly necessary for the effective operation of your website, increasing its performance and improving the user experience.
Code optimization helps speed up web page loading and reduce RAM consumption. Even for complex libraries, you can find more compact and efficient alternatives that provide similar functionality with less code. This not only improves site performance but also positively impacts user experience.
To implement common jQuery functionality, only about 5 KB of scripts, sometimes even less, are needed. Meanwhile, the minified version of the library itself takes up 88 KB. This comparison highlights the effectiveness of using small scripts to achieve the desired result without the need to load large libraries. Code optimization and the use of lightweight solutions can significantly improve the performance of web applications and speed up page loading time.
