The byteOffset accessor property of DataView instances returns the offset (in bytes) of this view from the start of its ArrayBuffer or SharedArrayBuffer.

The await operator is used to wait for a Promise and get its fulfillment value. It can only be used inside an async function or at the top level of a module.

A WeakSet is a collection of garbage-collectable values, including objects and non-registered symbols. A value in the WeakSet may only occur once. It is unique in the WeakSet's collection.

The alignment-baseline attribute specifies how an object is aligned with respect to its parent. This property specifies which baseline of this element is to be aligned with the corresponding baseline of the parent. For example, this allows alphabetic baselines in Roman text to stay aligned across font size changes. It defaults to the baseline with the same name as the computed value of the alignment-baseline property.

The decrement (--) operator decrements (subtracts one from) its operand and returns the value before or after the decrement, depending on where the operator is placed.

The Int16Array typed array represents an array of 16-bit signed integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

This chapter documents all the JavaScript language operators, expressions and keywords.

The <vkern> SVG element allows to fine-tweak the vertical distance between two glyphs in top-to-bottom fonts. This process is known as kerning.

The Float64Array typed array represents an array of 64-bit floating point numbers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

A FinalizationRegistry object lets you request a callback when a value is garbage-collected.
