Today most developers rely upon existing code to help us cut developing time to
the absolute minimum. For similar reasons new language features are constantly
added to JavaScript and other programming languages.
We evolve and become better at finding working solutions fast. At the same time
we slowly forget to look behind the scene how the system actually works.
Users expect services to respond very fast or they might leave and try out a
different product. With cloud providers it's possible to scale up easily but we
pay for our CPU time and memory usage. Thus, having slow code is expensive.
Let's dive into performance issues and how to make sure you always provide the
best experience for everyone. Yourself and your customer. Let us stop doing
unnecessary work.
