History of Scala programing language

History of Scala

Scala may be a general purpose programing language . it had been created and developed by Martin Odersky. Martin started performing on Scala in 2001 at the Ecole Polytechnique Federale de Lausanne (EPFL). it had been officially released on January 20, 2004. A second, Revised Version , described was released in March 2006. Scala isn't an extension of Java, but it's completely interoperable with it.    

Definition of Scala

Scala may be a strong statically typed general-purpose programing language which supports both object-oriented programming and functional programming. Designed to be concise, many of Scala's design decisions are aimed to deal with criticisms of Java Scala is a general-purpose, high-level, multi-paradigm programming language. Scala is a pure object-oriented programming language. Scala programs can be convert in to byte codes and it can run on the JVM (Java Virtual Machine). Scala stands for Scalable language. It also provides Javascript runtimes. Scala Functions Scala supports functional programming approach. It provides rich set of built-in functions and allows you to make user defined functions also.

Scala is functional

In Scala, there are not any static variables or methods. Scala uses singleton object, which is actually class with just one object within the source file. Here you don,t require to say data type and performance return type explicitly. Scala is enough smart to deduce the sort of knowledge . In Scala evaluation is lazy by default. Scala evaluates expressions only they're required.

Top 10 Uses of Scala

1. A multi-paradigm language

Scala being a language that supports both object-oriented programming and functional programming is sweet to find out . Learning this it builds imperative, logical, functional and OOP skills. you'll easily explore each side of functional and OOP together. Scala enables you to define differing types related to both data attributes and behavior attributes. Scala functions are considered as a primary class which allows you to pass values and also supports anonymous functions. This makes it elegant and is one among the most important reasons for Scala becoming so popular within the market.

2. It are often utilized in amalgamation with Java

Scala runs on Java Virtual Machine (JVM). It depends on the person using Scala if they need to use Java. This inter-operability feature of Java is one among the simplest options in Scala. it's also beneficial for Java developers as they will easily leverage their skills in Scala also . it's also possible to call Scala code from Java and user can easily write any a part of a program in Scala and rest in Java. This feature hence enables a user to write down code in Java and Scala and work along side both these languages.

3. Patterns built-in language

Scala was developed at Swiss University with an intention of making new innovations within the programming languages research to mainstream languages like Java. This language already has some best practices and patterns that are inbuilt the language. Variables are immutable and may be easily overloaded in Java. additionally to the present , it also offers to adopt new languages like Python, Ruby, etc. to implement functional programming.

4. A language that expresses

Scala may be a language that's inherently more expressive than Java. The developers who learn Scala after Java find it easier and interesting to write down code in Scala. to urge the sweetness of this language as compared with Java allow us to see an example. quality libraries to access. Support for .NET Framework (CLR) is additionally available.

Advantages of using Scala

• Object-oriented & functional programming language
• Compatibility and Interoperability with Java
• Scala is a concise programming language
• Class composition
• Processing in real-time
• Vast ecosystem
• Libraries for data science and data analysis
• Growing community

Among the advantages offered by Scala is that the quantity of code needed for the program is a smaller amount than necessary with the Java language, and therefore the incontrovertible fact that it's compatible with the Java Virtual Machine. the cash required to bring Scala to the market comes from Greyak Partners, who already finances tech companies like Red Hat or Cloudera.

Disadvantages of Scala

Sometimes type information may be a bit harder to know due to it being a hybrid of functional and object-orientation. It runs on JVM so it's no tail-recursive optimization. Since with Scala, you'll always switch back to an object-oriented paradigm. you'll consider this as a double-edged sword. Being a hybrid of functional and object-oriented can sometimes make type-information a touch harder to know . As a workaround, you'll use the @tailrec annotation for partial benefits. Scala features a limited developer pool. But while it's easier to seek out Java developers in numbers, not every Java developer has what it takes to code efficiently in Scala.
