Same as Java it also convert the source code to byte code hence it require JVM in order to execute the program. You can learn more about it from this link.
For many of us term Syntactic Sugar could be something out of this world and the term is too much heavy that anyone would wonder about this alien word. But many times the concept behind such terms is very simple. Now let’s make this word easily understandable. In such cases, I always split the term into separate words and try to understand the meanings of individual words in programming world prior to understand actual meaning the term.
Before we understand practical capacities of Scala language or attempt to learn core ideas of lambda expressions in Java, it is more crucial to understand the concept of Functional Programming first.
Most of the popular programming languages (like C, C++ and Java) are primarily created to follow the methodology of Imperative Programming, which implies that programmer generally write a code block (sequence of statements) which will change the state of the program(value of the variables) as each line is executed step by step.
