Scala a general-purpose, functional programming language with a strong static type system. Designed to be concise, many of Scala's design decisions were inspired by criticisms of Java's shortcomings. Having a basic familiarity with the programming language used on the job is a prerequisite for quickly getting up to speed.
Exceptions exist in most modern programming languages, making it important for a programmer to understand them and know how to handle them.
The string data structure is used to represent text. It is one of the most commonly used data structures. Therefore, every programmer should be skilled at string manipulation.
Arithmetic is a fundamental branch of mathematics. An understanding of arithmetic concepts, and their application, is important for every candidate.
Everyone makes mistakes. A good programmer should be able to find and fix a bug in their or someone else's code.
In object-oriented programming, inheritance is the mechanism of basing a class upon another class, retaining similar implementation. Inheritance allows programmers to reuse code and is a must know topic for every programmer who works with OOP languages.
Object-oriented programming is a paradigm based on encapsulating logic and data into objects, which may then contain fields and procedures. Many of the most widely used programming languages are based on OOP, making it a very important concept in modern programming.
As opposed to strict evaluation, which runs code immediately when encountered, in lazy evaluation code evaluation is deferred until the value is needed. This provides the benefits of potential performance increases.
LazyList is an immutable linked list that evaluates elements in order and only when needed. It is used when elements are not known ahead of time or when it is better to get them one by one, as needed.
