alternative

Front

A branch of a match expression. It has the form "case pattern => expression." Another name for alternative is case.

Does Scala overload operator?

Front

No. Instead, Scala has characters such as +, -, *, and / can be used in method names

Back

Parameterize arrays with types

Front

When you instantiate an object in Scala, you can parameterize it with values and types.Parameterization means "configuring" an instance when you create it. Example: val big = new java.math.BigInteger("12345")

The Challenge/Scala

Moore's Law

the observation that computing power roughly doubles every two years.

Scala

Front

Scala is a general-purpose programming language principally targeting the Java Virtual Machine. Designed to express common programming patterns in a concise, elegant, and type-safe way, it fuses both imperative-programming and functional-programming styles. Its key features are: Static typing Advanced type system with type inference and declaration-site variance Function types (including anonymous) which support lexical closures Pattern-matching Implicit parameters and conversions which support the typeclass and enrich-my-library patterns Mixin composition Full interoperability with Java Powerful concurrency constructs Advanced language constructs such as delimited continuations and an experimental macro system steps, stairs, ladder

Use of lists

Front

Immutable sequence of objects that share the same type you canuse Scala's List class Example: val oneTwo = List(1, 2) val threeFour = List(3, 4) val oneTwoThreeFour = oneTwo ::: threeFour println(oneTwo + " and " + threeFour + " were not mutated.") println("Thus, " + oneTwoThreeFour + " is a new list.")
