Closures in Scala
Before we begin discussing closures in Scala, let us have a quick look at a function. The function literal bill below accepts only one input parameter: netBill. However, the function calculates the...
Partial Functions in Scala
As the name suggests, partial functions are only partial implementations. They do not cover every possible scenario of incoming parameters. A partial function caters to only a subset of possible da...
Currying in Scala
Currying is named after Haskell Curry, an American mathematician. He is known for his work in combinatory logic. Currying is a means of transforming a function that takes more than one argument in...
Partially Applied Functions in Scala
Scala, like many other functional languages, allows developers to apply functions partially. What this means is that, when applying a function, a developer does not pass in all the arguments define...
Tail Recursion in Scala
Introduction Recursion is quite common in the programming world. As you probably know, it’s the process of solving a problem by breaking it down into smaller subproblems. You can easily spot recurs...
Designing Resilient Microservices
Resilience is an essential consideration while designing microservices. A microservice should embrace failure, whenever it happens. A microservice should be designed for all known failures. A few o...
