Immediately invoked function expressions may be written in a number of different ways. [3] A common convention is to enclose the function expression – and optionally its invocation operator – with the grouping operator, [4] in parentheses, to tell the parser explicitly to expect an expression.
In JavaScript, an object is an associative array, augmented with a prototype (see below); each key provides the name for an object property, and there are two syntactical ways to specify such a name: dot notation (obj.x = 10) and bracket notation (obj['x'] = 10). A property may be added, rebound, or deleted at run-time.
The rest parameter must be the final named parameter in the function's parameter list. It will be assigned an Array containing any arguments passed to the function in excess of the other named parameters. In other words, it gets "the rest" of the arguments passed to the function (hence the name).

Then we will bind an event handler so that when this link is clicked, we will call another function named doQwikify() that will actually execute the code. The name is what is shown on the tab, so set that to 'Wikify'. Most tabs have an ID of ca-name, so set the ID to 'ca-wikify'.
In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more.This is accomplished by doing a convolution between the kernel and an image.
Haskell: Surrounding a function name by backticks makes it an infix operator. JavaScript: ECMAScript 6 standard introduced a "backtick" [10] character which indicated a string or template literal. Its applications include (but are not limited to): string interpolation (substitution), embedded expressions, and multi-line strings.
is a function from domain X to codomain Y. The yellow oval inside Y is the image of . Sometimes "range" refers to the image and sometimes to the codomain. In mathematics, the range of a function may refer to either of two closely related concepts: the codomain of the function, or; the image of the function.
