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 ...
CSS-in-JS is a styling technique by which JavaScript is used to style components. When this JavaScript is parsed, CSS is generated (usually as a <style> element) and attached into the DOM . It enables the abstraction of CSS to the component level itself, using JavaScript to describe styles in a declarative and maintainable way.
Though most polyfills target out-of-date browsers, some exist to simply push modern browsers forward a little bit more. Lea Verou's -prefix-free polyfill is such a polyfill, allowing current browsers to recognise the unprefixed versions of several CSS3 properties instead of requiring the developer to write out all the vendor prefixes.
Small utilities may be developed for counting the LOC in a program. However, a logical code counting utility developed for a specific language cannot be used for other languages due to the syntactical and structural differences among languages. Physical LOC counters, however, have been produced which count dozens of languages.
A CSS framework is a library allowing for easier, more standards-compliant web design using the Cascading Style Sheets language. Most of these frameworks contain at least a grid . More functional frameworks also come with more features and additional JavaScript based functions, but are mostly design oriented and focused around interactive UI ...
A function definition starts with the name of the type of value that it returns or void to indicate that it does not return a value. This is followed by the function name, formal arguments in parentheses, and body lines in braces. In C++, a function declared in a class (as non-static) is called a member function or method.
The connected component containing the special vertex contains the objects that can't be collected, while other connected components of the graph only contain garbage. If a reference-counting garbage collection algorithm is implemented, then each of these garbage components must contain at least one cycle; otherwise, they would have been ...
Reference counting garbage collection is where each object has a count of the number of references to it. Garbage is identified by having a reference count of zero. An object's reference count is incremented when a reference to it is created and decremented when a reference is destroyed. When the count reaches zero, the object's memory is ...
