This chapter introduces collections of data which are ordered by an index value. This includes arrays and array-like constructs such as Array objects and TypedArray objects.

The clip attribute defines the visible region of an element. You should use clip-path instead.

JavaScript Date objects represent a single moment in time in a platform-independent format. Date objects encapsulate an integral number that represents milliseconds since the midnight at the beginning of January 1, 1970, UTC (the epoch).

The clipPathUnits attribute indicates which coordinate system to use for the contents of the <clipPath> element.

The division assignment (/=) operator performs division on the two operands and assigns the result to the left operand.

The <linearGradient> SVG element lets authors define linear gradients to apply to other SVG elements.

The gradientUnits attribute defines the coordinate system used for attributes specified on the gradient elements.

This page describes JavaScript's lexical grammar. JavaScript source text is just a sequence of characters — in order for the interpreter to understand it, the string has to be parsed to a more structured representation. The initial step of parsing is called lexical analysis, in which the text gets scanned from left to right and is converted into a sequence of individual, atomic input elements. Some input elements are insignificant to the interpreter, and will be stripped after this step — they include white space and comments. The others, including identifiers, keywords, literals, and punctuators (mostly operators), will be used for further syntax analysis. Line terminators and multiline comments are also syntactically insignificant, but they guide the process for automatic semicolons insertion to make certain invalid token sequences become valid.

An object providing access to an open file on the filesystem.

The repeatDur attribute specifies the total duration for repeating an animation.
