What is jQuery and why is it so slow?

jQuery is an outdated JavaScript library that simplifies manipulating HTML elements and handling events on web pages for developers.

The jQuery script alone is already 80KB, which is 4X that of the Mida script, and this additional loading time has nothing to do with running tests on your website.

It is unnecessary for modern websites, jQuery introduces a lot of redundant functionalities that most modern websites can already support natively without it.

Why should I care about my website speed?

What are the benefits of a fast loading website and why is site speed an important factor to consider? Let’s take a look at some of the key elements:

  • Search engines prioritize fast-loading websites, the heavier your website is the lower search engine rankings Google will put you.
  • Users expect websites to be responsive and load quickly, a heavy script can slow down website performance, frustrating users and potentially increasing bounce rates. Remember, 47% of users expect a web page to load in 2 seconds or less.
  • Browsers such as the Chrome browser are starting to warn their users when they are about to visit a slow loading site.
  • Slow testing script leads to flickering effect and it will distracts users, reduces trust, skews results, and increases bounce rates, leading to lower conversion rates.
  • A lighter and faster site generally means that less data is being transmitted and loaded which means that less electricity is used. A lighter site emits less carbon for each and every visitor.

How can you measure your website speed and analyze script sizes?

To measure your website speed and evaluate the impact of various scripts, you can use tools like GTmetrix. This tool provides valuable metrics like the PageSpeed Score, load time, and overall page size. The Waterfall chart in GTmetrix visualizes the loading process of individual website elements, including scripts from your analytics provider.
