With lambda expressions, we can encapsulate code in order to call it later, and that also might be somewhere else because we can copy them around. We can also just encapsulate code to call it multiple times with slightly different parameters without having to implement a whole new function class for that task.
The syntax of lambda expressions was really new in C++11, and it has slightly evolved with the next two standard versions until C++17. In this section, we will see what lambda expressions can look like and what they mean.
