LinkedIn principal author Doug Winnie explains the basic history of programming and how programming languages have evolved over time to support evolutions in hardware and computer technology. Starting with Ava Lovelace in the 1840s, programming now uses specialized languages that, when used together, can create new products and push innovation further.

- In the early 1840s Charles Babbage proposed…a machine called the Analytical Engine.…It was only a proposal, no actual machine was built,…but one inventive woman by the name of Ada Lovelace…decided to write an article that provided…detailed instructions on how to represent…Bernoulli numbers, a recursive equation…based in number theory on the Analytical Engine.…This article is considered to be…the very first computer program.…Since then the devices that can be programmed…went from theoretical to physical,…manual to automatic, analog to digital.…
With each evolutionary step…the way we program computers needed to evolve as well.…With the birth of main frame computers,…data processing required instructions…to be sent to the machine…and interpret the instructions from the programmer.…This was then applied to data to organize and analyze it.…Instructions were entered through a keyboard…but without a monitor, so everything was done…through printouts on paper.…If you look carefully at text encodings…and at some programming languages,…
Join Doug Winnie as he explains the principles of programming and helps you connect to core concepts by exploring three ways that programmers perform their jobs. Doug starts by sharing the history of coding and then dives into functions, values, variables, and parameters used to define actions. He covers capturing input from users, creating conditional tests, using loops with arrays, and object-oriented programming basics. He also takes you beyond programming, into processes like debugging, refactoring, and building iteratively.

- Customizing functions and parameters
- Building conditional tests
- Creating and changing arrays
- Working with objects and classes
