GET is designed for getting data from the server. POST (and lesser-known friends PUT and DELETE) are designed for modifying data on the server. A GET request should never cause data to be removed from an application. If you have a link you can click on with a GET to remove data, then Google spidering … Read more
As of C++14, they often are. C++14 adds a fringe case where parentheses around a return value may alter the semantics. This code snippet shows two functions being declared. The only difference is parentheses around the return value. int var1 = 42; decltype(auto) func1() { return var1; } // return type is int, same as … Read more
Thanks for this interesting question. There are few more things to consider here. What is a pair? Two elements together. So we need a tag for this. Let’s say it is pair tag. <pair></pair> The pair contains the key, and the corresponding value: <pair><key>keyname</key><value>value</value></pair> Then, we need to list the pairs: <pairlist> <pair><key>keyname</key><value>value</value></pair> <pair><key>keyname</key><value>value</value></pair> </pairlist> … Read more
Prior to HTML5: The anchor has to be inside the header, you cannot put a block-level element inside an anchor, and most browsers will not render it 100% reliably if you do. In HTML5: It doesn’t matter, use whichever one makes the most semantic sense. Likely the first one. Remember that if your document is … Read more
Yes, but with a catch. The W3 documents state that the tags represent the header and footer areas of their nearest ancestor section. I would recommend having as many as your want, but only 1 of each for each “section” of your page, i.e. body, section etc. From W3 A header element is intended to … Read more
Are all statements also expressions? “Wherever JavaScript expects a statement, you can also write an expression. Such a statement is called an expression statement. The reverse does not hold: you cannot write a statement where JavaScript expects an expression. For example, an if statement cannot become the argument of a function.” This is comes from … Read more
You could use event delegation on the parent div. Or use the closest method to find the parent of the button. The easiest of the two is probably the closest. var id = $(“button”).closest(“div”).prop(“id”);
Well, the type could be considered poorly named, for one. A KeyValuePair as named should represent a key and a value. What if your two objects aren’t really a key and a value, just two things? If I were to see a method or property that had a type of KeyValuePair<TKey, TValue>, I would expect … Read more
It seems to me that it’s mostly a matter of style: I strongly prefer using properties for just that: properties; meaning simple values that you can get and/or set. I use functions (or methods) when actual work is being done. Maybe something has to be computed or read from disk or from a database: In … Read more
Simple. When I use it, it’s a modern dynamic language, when you use it, it’s merely a scripting language!
