JavaScript is designed on an object-based paradigm. An object is a collection of properties, and a property is an association between a name (or key) and a value. A property's value can be a function, in which case the property is known as a method.

Loops offer a quick and easy way to do something repeatedly. This chapter of the JavaScript Guide introduces the different iteration statements available to JavaScript.

Every property in JavaScript objects can be classified by three factors:

The <line> SVG element is an SVG basic shape used to create a line connecting two points.

The <feGaussianBlur> SVG filter primitive blurs the input image by the amount specified in stdDeviation, which defines the bell-curve.

A Promise is an object representing the eventual completion or failure of an asynchronous operation. Since most people are consumers of already-created promises, this guide will explain consumption of returned promises before explaining how to create them.

Low-level languages like C, have manual memory management primitives such as malloc() and free(). In contrast, JavaScript automatically allocates memory when objects are created and frees it when they are not used anymore (garbage collection). This automaticity is a potential source of confusion: it can give developers the false impression that they don't need to worry about memory management.

The <path> element is the most powerful element in the SVG library of basic shapes. It can be used to create lines, curves, arcs, and more.

JavaScript typed arrays are array-like objects that provide a mechanism for reading and writing raw binary data in memory buffers.

The <a> SVG element creates a hyperlink to other web pages, files, locations in the same page, email addresses, or any other URL. It is very similar to HTML's <a> element.
