conclusion

• jQuery is a JavaScript file you include in your pages.
• Once included, it makes it faster and easier to write cross-browser JavaScript, based on two steps:
  • Using CSS-style selectors to collect one or more nodes from the DOM tree.
  • Using jQuery’s built-in methods to work with the elements in that selection.
• jQuery’s CSS-style selector syntax makes it easier to select elements to work with. It also has methods that make it easier to traverse the DOM.
• jQuery makes it easier to handle events because the event methods work across all browsers.
• jQuery offers methods that make it quick and simple to achieve a range of tasks that JavaScript programmers commonly need to perform.
