Mutable vs Immutable Objects Explained: Practical examples & use cases in PHP
In this video, we dive into the concept of mutable and immutable objects in programming. We'll explore what makes an object mutable or immutable and why it matters. Using practical examples, we'll demonstrate how mutable objects like DateTime can lead to unintended changes and how immutable objects can help prevent these issues by creating new instances for modifications.
We'll also create our own mutable and immutable object, a Counter, to illustrate the differences clearly. By the end of this video, you’ll understand when to use mutable or immutable objects in your projects and the trade-offs between performance and error-prone code.
