JavaScript Diary II
Learn JavaScript essentials from a compiled language perspective. Explore practical tips and best practices in this technical deep dive with expert insights.
In my previous post I have written about some JavaScript basics from the point of view of Software Engineering and Architecture. In this post I will stay close to the metal. I will talk about a few things we should care about in JavaScript language. Things that should or shouldn't be in the code.
I am from a hard core compiled language background. My first company was a Game Company where I built kind of a Game Engine and my second company I worked on C++. Even in my third company I was working on a web project but most of the time I stayed on the server end. So, I had the support of the managed nature of C Sharp. But in the case of JavaScript it is not true. And many times people make mistakes that I did. They take JavaScript as a compiled language and work like that only. Obviously it's like other programming languages only, it's all about if and else but it's a little bit different. My this post is going to be completed by the video of Channel9. Here I am attaching the video, too. Please go through the video and check out what should be taken care of while writing JavaScript. It's 50 minutes long and obviously worth spending 50 minutes.
Here is the video.
So, here are the details that are shown in the video.
Please go through this. It's worth watching and learning.
Frequently Asked Questions
Many developers, especially those coming from compiled language backgrounds like C++ or C#, mistakenly treat JavaScript as a compiled language. This leads to coding practices that don't account for JavaScript's dynamic nature and lack of compile-time checks. Understanding JavaScript's unique characteristics is essential to avoid these pitfalls.
JavaScript is an interpreted, dynamically-typed language without the safety net of compile-time error checking that C++ and C# provide. While the basic control flow (if/else statements) is similar across languages, JavaScript requires developers to be more careful about type handling and runtime behavior since errors won't be caught until execution.
Developers should focus on understanding JavaScript-specific language features and best practices rather than applying patterns from compiled languages. The video referenced in the post covers key details about what should and shouldn't be included in JavaScript code, emphasizing language fundamentals over architectural patterns.
While JavaScript shares fundamental programming concepts like conditionals with other languages, it has significant differences due to its interpreted nature and dynamic typing. These differences require developers to adopt a different mindset and be aware of JavaScript-specific gotchas and best practices.
