Reading Time: 3 minutes Overview In this blog, we will show a functional feature of Scala which is pattern matching. If you have used Java or .NET in the past, it may at first sight appear similar to switch statements. But, Scala’s pattern matching is a lot more powerful! Different ways of Pattern Matching 1. Pattern matching – a very basic example Suppose you want to test a variable called donutType. In the case that its value Continue Reading

Pattern Matching In Scala | Basic & Advanced Pattern Match

Simple Guidance For You In Case Class And Pattern Matching

Reading Time: 2 minutes Case classes are like regular classes that have default apply() method which handle object construction. There is no  need to use a new keyword to create an object. Case class provides purely functional code with immutable objects. Case classes are a representation of a data structure with the necessary methods. It support pattern matching. Syntax of case class:- Example:-  When you create a case class Continue Reading

Pattern Matching: The Most Powerful Tool of Functional Programming

Reading Time: 2 minutes Hi, community, in this blog, we will be covering what is pattern matching, when should we use it, and at the end, we’ll compare it with if-else. What is Pattern Matching? Pattern Matching is one of the most powerful tools in Scala. It’s similar to a switch statement in java but with loads of functionalities in comparison to a switch statement. Definition Pattern Matching is Continue Reading

How to use Pattern Matching in Rust

Reading Time: 3 minutes Rust has an extremely powerful control flow operator called Match. Pattern matching in Rust works by checking if a place in memory matches a certain pattern. Patterns can be : literal values variable names wildcards, and many other things Destructuring using Pattern Matching Pattern matching can use to destruct following items : Structures Enums Tuples  Destructuring breaks up a value into its component pieces. The syntax used is Continue Reading

Pattern Match Anything in Scala

Reading Time: 7 minutes What is Pattern Matching? Pattern matching is a powerful feature of the Scala language. It is a mechanism for checking a value against a pattern. A successful match deconstructs the value into its constituent parts. Pattern matching allows for more concise and readable code while at the same time provide the ability to match elements against complex patterns. In this blog, we will see the Continue Reading

Scala Extractors

Scala: Extractors and Pattern Matching

Reading Time: 3 minutes An extractor in Scala is an object which has an unapply method as one of its members. Often, the extractor object also defines a method apply for building values, but this is not required. An apply method is like a constructor which takes arguments and creates an object, the unapply method takes an object and tries to give back the arguments. The unapply method reverses the construction procedure of the Continue Reading

Scala Extractors

Back2Basics: Scala Extractors in Detail

Reading Time: 5 minutes While working with the Case Classes closely, we have a very concise way to decompose an entity using pattern matching. The potent example is pattern matching on the Some(x) and None, as most of us know they are case class and case object respectively. The potential question that we have is do we have a provision to use similar patterns without having an associated case Continue Reading
