jQuery is a fast, lightweight, and feature-rich JavaScript library that simplifies HTML document traversing, event handling, animating, and Ajax interactions. It has been a popular choice among web developers for many years due to its ease of use and cross-browser compatibility. Before diving into the timeline of learning jQuery, it’s crucial to understand what it is and why it’s still relevant in modern web development.
jQuery was first released in 2006 by John Resig and has since become one of the most widely used JavaScript libraries. Its primary goal is to simplify the client-side scripting of HTML, making it easier for developers to create dynamic and interactive web pages. The library’s motto, “Write less, do more,” encapsulates its core philosophy of providing a concise and efficient way to manipulate the Document Object Model (DOM), handle events, create animations, and make Ajax calls.
