Can we learn something practical from a pure computer science interview question? In this article we will solve an interview question and optimize it – but we will also look at a practical way to handle data in real life.…
Finding a single unique number in a list containing pairs might sound pretty simple, right?
Because a one-sentence description might be misleading, let’s start with an example of an input array:

The Array Nesting interview question might seem complex at first and very simple after you solve it. But sometimes, a deeper dive into it can expose some more performance optimizations that can be interesting. After this article, you’ll be able …
Google’s Material Web Components had a performance issue and I thought I could help. The results: 90% performance improvement in big lists removal. Here’s how I did it, and how you can duplicate it in your application.
In the former article, we saw how to measure the JS heap in the browser and a few use cases it can come in handy. I was asked how this can be done in a nodejs app as well.

Part of the tools frontend developers have in their arsenal is the performance API. Part of it is the memory object. It can be used for various causes – from debugging performance through experimenting to performance budget monitoring.
Force reflow (or Layout Reflow) is a major performance bottleneck. It happens when a measurement of the DOM happens after a DOM mutation. With this knowledge, I was able to improve performance of an app in my workplace by 75%. …
In my last article, I talked about the flyweight design pattern. I mostly talked about how it can save you (and your end user) bandwidth.
I failed to mention the save on memory.
If we continue the example from …
My talk (in Hebrew) at Javascript Israel about Optimization Patterns in Javascript is now online. Enjoy 🙂
My video from confrontJS about reducing garbage collection with the Object Pool design pattern is now live on YouTube!
