Error handling with Async/Await in JS
This will be a small article, based on some issues I picked up during code reviews and discussions with other developers. This article is rather focused on the novice JS developers.
A Simple Try Catch
Let’s start with the simple try...catch example.
function thisThrows() {
throw new Error("Thrown from thisThrows()");
}
try {
thisThrows();
} catch (e) {
console.error(e);
} finally {
console.log('We do cleanup here');
}
// Output:

Backend frameworks are the most critical building blocks that make application development easier and practical. Most developers, and clients for whom the developers create apps, have a problem choosing a backed framework. For a long time, .NET has played a crucial role as the go-to framework to develop the core elements of the apps.
On the other hand, front-end frameworks are the pioneering blocks that define how the user will interact...

Why do we need lifecycle hooks?
Modern front-end frameworks move the application from state to state. Data fuels these updates. These technologies interact with the data which in turn transitions the state. With every state change, there are many specific moments where certain assets become available.
At one instance the template might be ready, in another data will have finished uploading. Coding for each instance requires a means of detection. Lifecycle hooks...

It works perfectly in web-browsers without the help of any web-server or a compiler. It allows you to change HTML and CSS in the browsers without a full page reload. That is why it is used to create dynamic and interactive web...
