The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
The Windows Library for JavaScript (abbreviated as WinJS) is an open-source JavaScript library developed by Microsoft. It has been designed with the primary goal of easing development of Windows Store apps for Windows 8 and Windows 10 , as well as Windows Phone apps for Windows Phone 8.1 , Windows 10 Mobile and Xbox One [ 1 ] applications using ...
The default type value for the script element in Internet Explorer is JavaScript, while JScript was its alias. [10] In an apparent transition from JScript to JavaScript, online, the Microsoft Edge [Legacy] Developer Guide refers to the Mozilla MDN web reference library as its definitive documentation. [ 11 ]
In computer programming languages, a switch statement is a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution via search and map.
This code contains four different instructions; it first looks in the collection of windows for a window with the name "Main", then looks in that window's views collection for the 5th subview within it, then calls the size method to return a structure with the view's dimensions, and finally calls the width method on that structure to produce a ...
The dangling else is a problem in programming of parser generators in which an optional else clause in an if–then(–else) statement can make nested conditional statements ambiguous. Formally, the reference context-free grammar of the language is ambiguous , meaning there is more than one correct parse tree .
The ability to run JavaScript code on the server is often used to generate dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "JavaScript everywhere" paradigm , [ 6 ] unifying web-application development around a single programming language , as opposed to using different languages for ...
