Solidity is a `curly-bracket language <https://en.wikipedia.org/wiki/List_of_programming_languages_by_type#Curly-bracket_languages>`_
|
|
that has been influenced and inspired by several well-known programming languages.
|
|
|
|
Solidity is most profoundly influenced by C++, but also borrowed concepts from languages like
|
|
Python, JavaScript, and others.
|
|
|
|
The influence from C++ can be seen in the syntax for variable declarations, for loops, the concept
|
|
of overloading functions, implicit and explicit type conversions and many other details.
|
|
|
|
In the early days of the language, Solidity used to be partly influenced by JavaScript.
|
|
This was due to function-level scoping of variables and the use of the keyword ``var``.
|
|
The JavaScript influence was reduced starting from version 0.4.0.
|
|
Now, the main remaining similarity to JavaScript is that functions are defined using the keyword
|
|
``function``. Solidity also supports import syntax and semantics that
|
|
are similar to those available in JavaScript. Besides those points, Solidity looks like
|
|
most other curly-bracket languages and has no major JavaScript influence anymore.
|
|
|
|
Another influence to Solidity was Python. Solidity's modifiers were added trying to model
|
|
Python's decorators with a much more restricted functionality. Furthermore, multiple inheritance, C3 linearization,
|
|
and the ``super`` keyword are taken from Python as well as the general assignment and copy semantics of value
|
|
and reference types.
