Immutable Collections Deep Dive
Explore fundamental immutable collections like List, Map, Set, and learn their efficient usage.
Immutable Collections: Overview
Welcome to immutable collections! In Scala, these are foundational for writing robust, concurrent, and predictable code, especially in functional programming.
We'll explore fundamental types like List, Map, and Set, focusing on their efficient and safe usage.
Why Immutability Matters
Immutability means that once a collection is created, it cannot be changed. Any operation that seems to 'modify' it actually returns a new collection.
- Predictability: Easier to reason about code.
- Thread Safety: No need for locks as data never changes.
- No Side Effects: Operations won't unexpectedly alter data elsewhere.
