and that language is JavaScript. If we look today, there are hundreds of programming language such as ruby,Java,Python, and C+, but these languages all need to be on a server, so if you’re building a website,
JavaScript code is written for, and by, humans, who need whitespace, formatting, and comments to be able to understand and debug the code. After the code is written, minifying software can be used in order to improve performance. This is because browsers can execute code without needing to...
The only thing we can tell for sure is that the function takes two arguments. We can guess the types. Maybe the first one is a string and the second one is a configuration object. But it is just a guess and we might be wrong. We have no idea what options go into the settings obj...
JavaScript's strict mode, introduced in ECMAScript 5, is a way to opt in to a restricted variant of JavaScript, thereby implicitly opting-out of "sloppy mode". Strict mode isn't just a subset: it intentionally has different semantics from normal code. Br
Regardless of which language wins in the end, I want to emphasize my main point: JavaScript as it stands today is painfully inadequate, we need to embrace the need for a new language and push forward! Props to all the people making this happen and here's to hoping that more Node ...
Many Internet Of Things (IoT) and real-time applications that are written in JavaScript and rely on Node.js to run, either on the server or through microcontrollers and system on a chip (SoC) platforms such as Puck.js or Tessel.
One of my favorite parts about the JavaScript community is that people choose to write it in so many different ways. Why do you want to ruin that with a style guide? Imagine if when Picasso was learning to paint, we told him what style h...
If we insert the tag node created bydocument.createElement, we may find the DOM looks the same as we do withdocument.createElementNS. So why do we need to specify a namespace when we create a node? Let’s have a look at this document: ...
Javascript or React First of all we have Javascript to blame and not React. This is not something we need to do because of the way React works or JSX. It's because of the way this binding works in JavaScript. Let's see what happens if we don't bind the event handler method to its...
Second, developers need to be vigilant and prevent exceptions from bubbling up to the core (top) Node.js event loop, as this would cause the Node.js instance to terminate, effectively crashing the program. To prevent the flow of exceptions, we pass errors back to the caller as callback pa...
