The join() method of TypedArray instances creates and returns a new string by concatenating all of the elements in this typed array, separated by commas or a specified separator string. If the typed array has only one item, then that item will be returned without using the separator. This method has the same algorithm as Array.prototype.join().

The values() method of TypedArray instances returns a new array iterator object that iterates the value of each item in the typed array. This method has the same algorithm as Array.prototype.values().

A closure is the combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). In other words, a closure gives a function access to its outer scope. In JavaScript, closures are created every time a function is created, at function creation time.

The JSON namespace object contains static methods for parsing values from and converting values to JavaScript Object Notation (JSON).

The <feOffset> SVG filter primitive enables offsetting an input image relative to its current position. The input image as a whole is offset by the values specified in the dx and dy attributes.

In programming, inheritance refers to passing down characteristics from a parent to a child so that a new piece of code can reuse and build upon the features of an existing one. JavaScript implements inheritance by using objects. Each object has an internal link to another object called its prototype. That prototype object has a prototype of its own, and so on until an object is reached with null as its prototype. By definition, null has no prototype and acts as the final link in this prototype chain. It is possible to mutate any member of the prototype chain or even swap out the prototype at runtime, so concepts like static dispatching do not exist in JavaScript.

The String object is used to represent and manipulate a sequence of characters.

The SyntaxError object represents an error when trying to interpret syntactically invalid code. It is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.

The Object type represents one of JavaScript's data types. It is used to store various keyed collections and more complex entities. Objects can be created using the Object() constructor or the object initializer / literal syntax.
