Hello, World!: A Brief History of Programming in 90 Languages
In 2006, a programmer climbed twenty-one flights of stairs because his elevator's software had crashed—again. By the time he reached his apartment, he'd decided to build a language that would make those bugs impossible. The White House ended up recommending it by name.
In 1964, two Dartmouth professors typed RUN at 4 AM and launched the personal computer revolution. In 1952, Grace Hopper built the first compiler, and nobody believed her. In 1995, Brendan Eich created JavaScript in ten days and accidentally became the most-used language on Earth.
Every one of these stories starts the same with someone typing a few lines and watching the screen print "Hello, World!"—two words that trace back to Brian Kernighan's 1978 C Programming Language, and before that, to a Bell Labs memo he wrote in 1974. It became the universal first program, the one thing every language has in common.
Hello, World! collects those moments—90 programming languages, 76 years, from 1948 to 2024. Each language gets one who made it, why, what the code looks like, and what happened next. Dip in anywhere or read it front to back and watch the entire history of programming unfold.

Dale Biagio
1 book9 followersDale Biagio is a Software Architect with over twenty-five years of
experience turning complex technology challenges into scalable
solutions, from early mobile platforms to modern enterprise AI.
He has built and led global engineering teams, driving digital
transformation across cloud, data, and AI disciplines, and holds
professional certifications in Enterprise Architecture, AWS, and
Azure AI. His business foundation is rooted in Harvard Business

A brilliant and surprisingly human journey through programming history
Hello, World! is an exceptional book. Intelligent, engaging, and far more human than I expected a book about programming languages to be. Rather than simply cataloging syntax or technical milestones, it brings the history of computing to life through the stories.
What makes this book so compelling is the way it connects each language to the people, problems, and moments that shaped it. It gives readers a deeper appreciation for the tools developers use every day, while remaining accessible enough for curious non-programmers (like myself) who are so eager to understand how the digital world was built.
The writing is clear, thoughtful, and full of fascinating context. I found myself not only learning, but also developing a new respect for the creativity, constraints, and ambition behind programming language design.
Highly recommended for anyone interested in the evolution of software. This is the kind of book that reminds me that code is not just technical, it is historical, cultural, and deeply human.

- I received this book in a Goodreads giveaway -
This was a great overview of some of the most influential coding languages to date. I’m a physics graduate student who minored in computer science in undergrad. I found this book to be not only useful but enjoyable! I learned little to none about WHY different languages evolved. Courses were too focused on how to use a select few that we never learned the why. This book really helped to fill in those gaps for me, while being a fun and interesting read!

Thank you to NetGalley for this ARC in exchange for review.
If you're even slightly interested in coding languages, I would definitely consider reading this. The different entries are short and sweet (with a cute note about whether they're endangered or not) while going more in depth into the more used or notable languages. Even for the languages that don't get a lot of time, it gives just enough information that if you wanted to look into it more by yourself you'd have the information to do.
You definitely need at least some coding knowledge to understand the terms, as they're not really explained, but I managed it just fine with a rudimentary understanding.
