Coding partner following JS best practices

[mohammadamin-alizadeh]

According to JavaScript Best Practices, DRY, KISS, YAGNI, and HTML & CSS:

Here are some issues related to JavaScript best practices:

• Use of document to access the DOM: The code uses document to access the DOM, which is not efficient and can slow down the application. A better approach would be to use a variable to store the element and then access it when needed.
• Unclear variable names: Some of the variable names used in the code are unclear and don't follow best practices for naming conventions. For example, Add and Remove don't accurately describe what the functions do.
• Inefficient code: The code could be made more efficient in certain areas. For example, the Display function is called multiple times, even when there is no need to update the display specifically in ClearAll. function.

The HTML code seems well-structured and follows best practices. However, here are a few suggestions:

• Use semantic HTML tags to improve the readability and structure of the page. For example, use for the header, for the main content area,
  for the different sections, for navigation, for the footer,
• Add alt text to the element for better accessibility.
