Function declarations, which declare a variable and assign a function to it, are similar to variable statements, but in addition to hoisting the declaration, they also hoist the assignment – as if the entire statement appeared at the top of the containing function – and thus forward reference is also possible: the location of a function ...
Ext JS version 2.0 was released on 4 December 2007. This version was promoted as providing an interface and features more similar to those traditionally associated with desktop applications.

In computing, a button (sometimes known as a command button or push button) is a graphical control element that provides the user a simple way to trigger an event, like searching for a query at a search engine, or to interact with dialog boxes, like confirming an action.

Modules have a function, context, and logic: [117] The function of a module is what it does. The context of a module are the elements being performed upon. The logic of a module is how it performs the function. The module's name should be derived first by its function, then by its context. Its logic should not be part of the name. [117]
JavaScript supports automatic semicolon insertion, meaning that semicolons that normally terminate a statement in C may be omitted in JavaScript. [16] Like C-style languages, control flow is done with the while, for, do / while, if / else, and switch statements. Functions are weakly typed and may accept and return any type.
Accessibility: If any script fails, the page still delivers its core functions and information via the markup, stylesheets and/or server-side scripting. Separation: For the benefit of other and future web developers, all JavaScript code is maintained separately, without impacting other files of script, markup or code.
In software engineering, dependency injection is a programming technique in which an object or function receives other objects or functions that it requires, as opposed to creating them internally. Dependency injection aims to separate the concerns of constructing objects and using them, leading to loosely coupled programs.
For a value of 1 it would return "one". For a value of 2 it would return "two". For the values 3, 4 or 5 it would return "range 3–5". For any other value, or a null value, it would return "other". However, in many cases, the #switch function is a multi-line form, with each branch on a different line, as follows:
