jQuery was created by John Resig and released in January 2006 at the BarCamp NYC conference. At that time, JavaScript was powerful but messy, mainly because different browsers (Internet Explorer, Firefox, Safari, Opera) interpreted it in their own ways. Developers often had to write separate code for each browser to make sure their websites worked properly.
John Resig built jQuery to solve this problem. His goal was to create a lightweight JavaScript library that simplified coding and made it possible to write cross-browser compatible scripts with ease.
