Solidity (2018)

Solidity, an interpreted imperative language, was built in the mid 2010’s by contributors to the Ethereum blockchain including Christian Reitwiessner and Alex Beregszaszi. Solidity is used for implementation of smart contracts onto blockchain platforms. Smart contracts are intended to eliminate unnecessary intermediaries involved in contractual agreements. Smart contracts are the backbone of decentralized applications. One well-known decentralized application is AAVE, a protocol that allows users to loan and borrow assets on the blockchain.

Go (2009)
Go, a compiled imperative language, was designed by Google engineers brought together by a shared distaste for C++. Many features of C and C++ are dated and difficult to work with, such as manual memory allocation. Go aims to recreate the functionality of C with greater ease-of-use and readability. Netflix, Paypal, and Twitter are some companies with applications powered by Go.

PHP (1995)

PHP, an interpreted imperative language, was created in 1994 by Rasmus Lerdorf and publicly released in 1995. Lerdorf originally wrote programs in C for maintenance of his personal website. As the use-cases of these programs expanded, Lerdorf’s continued implementations evolved into PHP. The language is still widely used in web development, with functionalities such as form handling and array management. Facebook, Wikipedia, and Slack are three websites that operate with PHP.

Python (1991)

Python, an interpreted imperative language, was developed in the late 80’s by Guido Van Rossum. Python’s intuitive, easy to read code makes it a frequent favourite for beginner and senior programmers alike. The design philosophy of Python emphasized the importance of readability, accessibility, and aesthetic value among other things. Python is a popular back-end language in web development, used by giants such as Reddit and Wikipedia.

C (1972)

C, a compiled imperative language, was conceived in the early seventies by Dennis Ritchie. An expansion of Bell Labs’ lesser-known B language, C has embedded itself into modern high-level programming procedures on a massive scale. C++, C#, Java, and Javascript, to name a few, are languages that are influenced functionally and syntactically by C. Any UNIX-based operating system is developed with C.
