Version 2.5 Changelog

Changelog for Version 2.4

• New Feature: Added a direct link to AliExpress for price comparison, allowing users to check prices of Amazon products on AliExpress with a single click.
• Optimizations:
  • Merged similar functions to reduce redundancy. Functions getPriceFromPage and getPriceFromResponse are now combined into getPriceFromDocument(doc).
  • Simplified handleResponse by using DOMParser to parse the response text into a document, improving efficiency when retrieving price and delivery fees.
  • Enhanced regular expression in getDeliveryPriceFromDocument for accurate capture of delivery fees, using a non-greedy quantifier *?.
  • Reduced redundancy by removing unused variables and functions, making the code more concise.
  • Standardized function usage across the codebase, improving readability and maintainability.
  • Cleaned up code to follow best practices, including proper spacing and commenting.
• Note: These changes keep the script's functionality intact but enhance code clarity, maintainability, and performance by avoiding unnecessary calls and processing.

Optimizations made in version 2.3:

• Merging of similar functions: The functions getPriceFromPage and getPriceFromResponse have been combined into a single function getPriceFromDocument(doc) to avoid redundancy.
• Simplification of handleResponse: Instead of calling two separate functions to obtain the price and delivery fees, we now use DOMParser to convert the response text into a document and pass this document to our functions getPriceFromDocument and getDeliveryPriceFromDocument.
• Improvement of the regular expression for delivery fees: In getDeliveryPriceFromDocument, the regular expression has been adjusted to correctly capture the delivery fees by using a non-greedy quantifier *?.
• Reduction of redundancy: Unnecessary or redundant variables and functions have been removed to make the code more concise.
• Consistent use of functions: All functions that extract information from the document now use a consistent approach, improving code readability and maintainability.
• Code cleanup: Minor improvements have been made to adhere to best practices, such as proper spacing and commenting.

Note:

• The script's functionality remains unchanged.
• The code is now clearer, shorter, and easier to maintain.
• The optimizations improve performance by avoiding unnecessary calls and processing.
