Hey everyone! Today, I want to introduce you to Part 1 of my series on one of the most interesting - and complex - structures in JavaScript: Generators!

Generators are a powerful tool that can be used to build other tools. They are essentially a special type of function that can produce a sequence of values one at a time while maintaining their own internal state and context.

Although not as well-known as other JavaScript features, generators are widely used in various frameworks and core language constructs like Promises and async/await. By understanding how generators work, you can take advantage of this powerful tool in your own applications.

In Part 2 of this series, I will dive into the real-world use cases of generators that can help boost your work! So stay tuned and don't miss out on the opportunity to level up your JavaScript skills!

💙 I'm back with the second part of the new typescript feature! Decorators.
In the last post we saw how we can use them to log the input and output of a function.

Today in addition we will also log the name of the function.

They are a great tool for mainly interceptor type functionality, but can also be used for much more with a bit of tinkering.

They are broadly adapted and heavily used by some of the biggest frameworks, like Angular.

So if you are working in a TypeScript environment, and there are some use-cases for you (e.g. a custom performance logger or a permissions check for backend methods), don't be afraid of using them.

📌 Part 2 of our MongoDB Atlas journey is here! In this post, we're diving into connecting to MongoDB Atlas using the Node.js driver. MongoDB is a great choice for modern web applications because of its flexibility and scalability. It is document-oriented, meaning it can easily store and query large amounts of unstructured data.

📌 By using the Node.js driver, we can take advantage of the power of MongoDB Atlas and easily connect our application to the cloud-based database. This allows for easy scaling, automatic backups and disaster recovery, and reduced maintenance and setup costs. Plus, with MongoDB Atlas, we have access to a wide range of features and tools to manage and optimize our database.

📌 Not only is MongoDB a great choice for web development, but learning it can also open up a lot of career opportunities in the tech industry. With the growing demand for NoSQL databases, learning MongoDB can give you a valuable skill set that is in high demand. So let's get started and see how easy it is to connect to MongoDB Atlas using the Node.js driver!

Are you constantly trying to optimize your JavaScript code for performance?

In this post, we'll explore the importance of avoiding over-optimization and why it's essential to focus on writing clean, maintainable code.

As developers, it's easy to get caught up in the pursuit of optimizing every last line of code. However, it's important to remember that the JavaScript engine is responsible for optimizing code ex*****on and minimizing the number of function calls. Additionally, trying to optimize code before understanding how it will be used can be a waste of time and effort.

In this example, the inner loop uses a more complex looping construct (a reverse for loop) to search for the target element in the array. However, this optimization is likely to have little or no impact on the overall performance of the code, as the difference in speed between the two loops is likely to be negligible.

While it's important to write efficient code, it's also important to consider the trade-offs between optimization and readability, maintainability, and development time. Micro-optimizations that have little or no impact on the overall performance of the code are generally not worth the effort.

This second version of the loop is much more readable and maintainable than the optimised version. It uses a descriptive function name, a clear looping construct, and a clear return statement. It is also likely to be just as efficient as the optimised version, as the difference in speed between the two loops is likely to be negligible.

Or maybe the best solution for your case is to use Typescript! 💙

📌 If you're working with simple data types like strings and numbers and you can't use polymorphism but you still feel the need to type-check, you may want to consider using TypeScript.

📌 It's a good option because it adds static typing to standard JavaScript syntax. One issue with manually type-checking regular JavaScript is that it can be verbose and hard to read, so the "type-safety" you get may not be worth the loss of clarity.

📌 A better approach is to write clean JavaScript, create thorough tests, and review your code carefully. Alternatively, you can do all of those things with TypeScript, which is a fantastic alternative.

👉 Type checking can be a useful tool for catching bugs and ensuring that your code is behaving as expected. However, it's important to use it judiciously and not rely on it too heavily.

🔶 In this post, we'll take a look at an example of code on the top that heavily relies on type checking and how it can lead to inflexible and fragile code. On the bottom, we have an example of code that takes a more dynamic approach by leveraging the power of JavaScript's dynamic type system and using techniques such as type coercion and type guards. This approach results in code that is more adaptable and easier to maintain.

🔶 By being mindful of the trade-offs involved in using type checking, you can write code that is more robust and easier to work with. So the next time you're considering adding a bunch of type checks to your code, take a moment to think about whether there might be a better way to solve the problem.

Are you tired of debugging endless if-else statements in your JavaScript code? 🤔

Did you know that conditionals can often be replaced with more concise and readable alternatives?

In this post, we'll explore why it's important to minimize the use of conditionals in your code and how to refactor them using functional programming techniques such as map, reduce, and filter.

By embracing a declarative approach to coding, you can write more maintainable and scalable code that is easier to understand and debug.

So next time you're tempted to reach for an if statement, take a moment to consider if there might be a better way to solve the problem. Your future self (and your colleagues) will thank you!

🚨🚨🚨 It's generally best to avoid negative conditionals in JavaScript (and in other programming languages) because they can make your code harder to read and understand.

📌Instead of using a negative conditional, you can often achieve the same result using a positive conditional statement.

📌This can make your code easier to read and understand because it explicitly states what condition must be met in order for the code to run.

📌Prefer functional programming over imperative programming

📌JavaScript isn't a functional language like Haskell, but it does have a functional twist. Functional languages are cleaner and easier to test.
Prefer this programming style whenever possible.
