The following code example shows a scriptable OnClick property. [ScriptableMemberAttribute] public EventHandler OnClick { get { return _onClick; } set { _onClick = onClick;} } You can assign a JavaScript function to this property so that JavaScript code can call it, as shown in the follo...
The problem of global variables is well documented in JavaScript—the language makes it trivial to store data globally where all functions can access it. This is a common source of bugs, too, because anything could have changed the value of a global variable, and hence the function could now...
Modules in TypeScript are the equivalent of namespaces in the .NET Framework. They’re a great way to organize your code and to encapsulate business rules and processes that would not be possible without this functionality (JavaScript doesn’t have a built-in way to provide this function). Th...
// AJAX request using JavaScript and PHP let xhr = new XMLHttpRequest(); xhr.open("GET", "api/data.php", true); xhr.onreadystatechange = function () { if (xhr.readyState === 4 && xhr.status === 200) { let response = JSON.parse(xhr.responseText); ...

The clever thing here is that getServerSideProps doesn't re-run on the client. In fact, this function isn't even included in our JavaScript bundles! This approach was super ahead of its time. Honestly, it's pretty friggin’ great. But there are some downsides with this: This strategy ...
If you are writing JavaScript for modern engines only or using CoffeeScript, you may use catch instead of fail.Promises also have a fin function that is like a finally clause. The final handler gets called, with no arguments, when the promise returned by getInputPromise() either returns a ...
