JavaScript Methods List: A Comprehensive Guide

JavaScript is a powerful programming language that can be used to create interactive web pages. One of the things that makes JavaScript so powerful is its long list of methods. Methods are functions that are attached to objects and can be used to perform various tasks.

In this article, we’ll look at some of the most common JavaScript methods. We cover methods of working with the DOM, event handling, and creating functions. We also provide some examples of using these methods in your own JavaScript code.

DOM Methods

DOM (Document Object Model) is a tree-like representation of a website. Allows JavaScript to interact with elements on a web page. The most common DOM methods include:

• getElementById(): Returns the element with the specified ID.
• querySelector(): Returns the first element that matches the specified selector.
• querySelectorAll(): Returns an array of all the elements that match the specified selector.
• appendChild(): Appends an element to the end of a parent element.
• insertBefore(): Inserts an element before another element.
• removeChild(): Removes an element from its parent element.

Event Methods

Events are notifications sent to JavaScript by the browser. They are used to respond to user actions, e.g. B. clicking a button or scrolling a page. Some of the more common event methods include:

• addEventListener(): Attaches an event listener to an element.
• removeEventListener(): Removes an event listener from an element.
• preventDefault(): Prevents the default action of an event from occurring.
• stopPropagation(): Prevents the event from bubbling up to the parent element.
• target: Returns the element that the event was triggered on.

Function Methods

Functions are blocks of code that can be reused. They are defined using the function keyword. Some of the most common function methods include:

• call(): Calls a function with the specified arguments.
• apply(): Calls a function with the specified arguments and a context object.
• bind(): Creates a new function that is bound to a specific context object.
• toString(): Returns a string representation of a function.
• length: Returns the number of arguments that a function expects.
