Events in JavaScript can be classified into several categories based on the nature of the interaction or the source of the event. Knowing the different types of events will allow you to handle user interactions and other occurrences more efficiently and organized.

Mouse Events

Mouse events are those that occur when the user interacts with the mouse. Some of the most common are:

• click: Triggered when an element is clicked.
• dblclick: Triggered when an element is double-clicked.
• mouseover: Triggered when the mouse cursor moves over an element.
• mouseout: Triggered when the mouse cursor leaves an element.
• mousemove: Triggered when the mouse moves within an element.

Example:

html

Keyboard Events

These events occur when the user interacts with the keyboard. The most common include:

• keydown: Triggered when a key is pressed.
• keyup: Triggered when a key is released.
• keypress: Triggered when a key is pressed and released.

Example:

html

Form Events

These events occur mainly in relation to HTML forms. The most used are:

• submit: Triggered when a form is submitted.
• change: Triggered when the value of a form element changes.
• focus: Triggered when an element gains focus.
• blur: Triggered when an element loses focus.

Example:

Load Events

These events relate to the loading of resources on the web page.

• load: Triggered when a resource (like an image or script) has been completely loaded.
• unload: Triggered when the page is about to be unloaded.

Focus and Blur Events

These events are activated when an element gains or loses focus.

• focus: Triggered when an element gains focus.

• setTimeout: Executes a function after a specific period of time.
• setInterval: Executes a function repeatedly at specific intervals.
