"JavaScript is a programming language used to add interactivity to a web page. jQuery simplifies JavaScript syntax and makes it easier to build interactive web pages that work across multiple browsers.

jQuery enables us to do three main things on a web page:

1. Events. Respond to user interactions.
2. DOM Manipulation. Modify HTML elements on the page.
3. Effects. Add animations.

"

In order to make interactive web pages with jQuery, it's useful to know a few things about JavaScript.

JavaScript is a programming language that jQuery is written in, and knowing JavaScript will be helpful for understanding and writing your code.

Some define:

Events

User interactions with a web page are called events.

We can write a function that specifies what to do when an event occurs. This function is called an event handler.

Another common user event is the keypress event. A keypress event occurs when a user types a key on the keyboard.

DOM:

These six jQuery methods let you control more aspects of HTML elements:

• .hide() hides the selected HTML element
• .show() displays an element
• .toggle() alternates hiding and showing an element
• .addClass() adds a CSS class to an element
• .removeClass() removes a class from an element
• .toggleClass() alternates adding and removing a class from an element
• Notice where .toggleClass() is located. You can replace .toggleClass() with any of the five other methods. While each method creates different effects, their usage is similar.
• There are three common jQuery methods that use these relationships to access and modify elements on the page.
• .next()

• The .next() method gets the next sibling of the selected element.

• .prev()

  The .prev() method gets the previous sibling of the selected element.

• .children()

  The .children() method gets the children of the selected element.

  If provided a selector, the .children() method can get a specific child.
