Code optimization techniques
Now that we understand the importance of performance optimization, let’s start with one of the most critical areas: code optimization. Writing efficient code is fundamental to improving the overall performance of your NestJS application. Even small improvements in how your code is structured and executed can lead to significant gains in speed and resource usage.
In this section, we’ll explore several techniques that will help you write cleaner, faster, and more maintainable code. The following techniques not only improve performance but also enhance the readability and scalability of your application.
Efficient data handling
In order to manage data efficiently, it’s important to do the following:
- Avoid unnecessary computations: Minimize the use of expensive operations inside loops or frequently called functions. Calculate values once and reuse them when possible.
- Optimize loops and iterations: Ensure that loops...
