writing libraries. They also come with enhanced features which are

not possible in high level languages. The gas cost or cost of

operation is low in the assembly and low-level languages. However,

they too have their drawbacks. Many important safety checks are

bypassed in the assembly languages. The maintenance of the low

level languages would always be an issue.

Hence, Solidity is the most widely used language for writing Smart

Contracts on Ethereum. You would find a lot of examples and

existing codes running in production on Solidity. Also, there are

frameworks on Solidity such as Truffle, Embark, and OpenZeppelin

to save the developer’s time. Hence, Solidity seems to be the safest

bait so far.

2.5.3 Solidity Features

What are the features that made Solidity to be widely used in the

Blockchain initiatives? Let’s look at the following features:

Solidity is a statically typed programming language. In Solidity,

the variables have to be declared before they can be assigned

values which is very similar to what we observe in Java, C,

C++, FORTRAN, Pascal, and Scala.

Solidity is partly designed after ECMAScript, and hence, its

syntaxes are pretty much similar to JavaScript. Hence, if a

programmer had already coded in JavaScript, Solidity would

be familiar.

However, unlike JavaScript, Solidity is an object-oriented

language and supports all the related features such as

encapsulation, inheritance, polymorphism, abstraction, function

overloading, etc.

Once compiled, Solidity is translated to bytecodes and can run

on the Ethereum Virtual Machine.

The best integrated development environment (IDE) to write a

Solidity program for beginners is REMIX which is an online browser
