Scala Programming In-Depth

Explore Scala strings: define and read strings, measure length, concatenate with plus or concat, compare with equals or ==, format with interpolation, and write multiline strings with strip margin.

Explore pattern matching in scala, using simple and case class examples, and master regex usage with scala's java-based regex utilities, including findFirstIn, findAllIn, and getOrElse.

Explore Scala packages and imports, learn how packages create namespaces for modularization and how imports access package members across connectors, cleansing, transformation, and storage.

Master Scala traits, their use for inheritance, and how they enable multiple inheritance with resolved methods. Understand value classes, their immutability, performance benefits, and universal trait.

Explore arrays in Scala: declare and initialize arrays of various types, access elements by index from zero, and use for loops, for each, and map to process data efficiently.

Explore arrays in Scala: create and manipulate arrays, multi-dimensional arrays, and identity matrices; learn mutability with buffers, concatenation, and range-based iteration for operations like sum, max, min, and average.

Explore functional programming in Scala by defining functions with def, comparing functions and methods, using named and default parameters, and recursion through factorial examples, including anonymous functions.

Learn how Scala sets store unique elements, with immutable by default and mutable variants, not preserving insertion order, and support operations like union, intersection, contains, and isEmpty.

This lecture explains Scala maps, distinguishing immutable and mutable maps, how keys must be unique, values may repeat, and how plus and minus return new maps or mutate.

Learn about Scala tuples as fixed-size, immutable containers with mixed types and how to access them with _1, _2. Explore options and iterators, including Some/None and hasNext/next for safe iteration.
