SCALA PROGRAMMING..??

WHAT IS SCALA PROGRAMMING

Hii guys ,today we are going to talk about remaining seven programming languages that you should look out for in 2019 .Now without further ado lets get to number 7 .Stay connected with the programming category.




Now let have a look on number 7^th programming language.

WHAT IS SCALA PROGRAMMING..?

                                                              

• Scala programming is a general-purpose programming language providing support for functional programming and a strong static type system. It is designed to be concise, many of Scala's design decisions aimed to address criticisms of Java.
• Scala is a type-safe JVM language that incorporates both object oriented and functional programming into an extremely concise, logical, and extraordinarily powerful language or high level language.
• Scala programming static types help avoid bugs in complex applications, and its JVM and JavaScript runtimes let you build high-performance systems with easy access to huge ecosystems of libraries.
• Scala programming allows you to define types associated with both data attributes (with classes behaving like C++/Java classes) and behavior attributes (with traits corresponding to Java interfaces).
• Scala programming has many features of functional programming languages like Scheme, Standard ML and Haskell, including currying, type inference, immutability, lazy evaluation, and pattern matching.

USES OF SCALA PROGRAMMING:-

1. Scala programming being a language that supports both object-oriented programming and functional programming is good to learn. Learning this it builds imperative, logical, functional and OOP skills.
2. Scala functions are considered as a upper most language which allows you to pass values and also supports anonymous functions. This makes it elegant and is one of the biggest reasons for Scala becoming so popular in the today's world.
3. Another use of Scala is that it has a very precise syntax. Java has very long syntax and that was not easy to learn while Scala is more readable and concise at the same time. The Scala compiler called as scalac can generate and work for a better code like to String(), equals(), etc.
4. A lot of things, ranging from machine learning to web apps. As a high-level general purpose language, Scala boasts an extensive range of possible applications. Scala allows developers to make good use of standard JVM features and Java libraries
5. Scala programming has the various libraries and hence it can be used to build many frameworks. Some companies are using SCALA as the main programming language in their softwares.
6. The main reason or use of Scala programming is to provide the better growth and job. Learning Scala will increase your demand and will make you even more marketable. Many companies like Twitter, LinkedIn, Foursquare, etc are using Scala. In near future, all investment banks and financial organisations will be using Scala due to its scalable nature. There are many companies who share effective ways of uses of Scala. It will soon be the first alternative to Java.

EXAMPLE OF SCALA PROGRAMMING:-
Basic example

The following example shows the differences between Java and Scala syntax:

// Java: int mathFunction(int num) { int numSquare = num*num; return (int) (Math.cbrt(numSquare) + Math.log(numSquare)); }
// Scala: Direct conversion from Java // no import needed; scala.math // already imported as `math` def mathFunction(num: Int): Int = { var numSquare: Int = num*num return (math.cbrt(numSquare) + math.log(numSquare)). asInstanceOf[Int] }	// Scala: More idiomatic // Uses type inference, omits `return` statement, // uses `toInt` method, declares numSquare immutable import math._ def mathFunction(num: Int) = { val numSquare = num*num (cbrt(numSquare) + log(numSquare)).toInt }
