Programming Languages

Python

• Created 1991 by Guido van Rossum
• Origin Netherlands, while working at CWI
• Named after Monty Python's Flying Circus
• Built on ABC language, influenced by C and Modula-3
• Philosophy Readability counts, explicit is better than implicit
• Used for AI/ML, data science, web backends, automation, scripting
• Why it won Easy to learn, massive ecosystem, versatile

JavaScript

• Created 1995 by Brendan Eich at Netscape
• Timeline Famously built in 10 days
• Original name Mocha, then LiveScript, then JavaScript (marketing)
• Built on Influenced by Java, Scheme, and Self
• Purpose Make web pages interactive
• Used for Web frontends, backends (Node.js), mobile apps, everything
• Why it won Only language that runs in browsers natively

TypeScript

• Created 2012 by Microsoft, led by Anders Hejlsberg
• Built on JavaScript - it's a superset that compiles to JS
• Why created Add static typing to catch errors at compile time
• Anders Hejlsberg Also created Turbo Pascal, Delphi, and C#
• Used for Large-scale web apps, anything JavaScript does but safer
• Why it won Makes JavaScript manageable for big codebases

C

• Created 1972 by Dennis Ritchie at Bell Labs
• Built on B language (Ken Thompson), which came from BCPL
• Purpose Rewrite Unix in a high-level language
• Legacy Foundation for C++, Java, C#, Go, Rust, and many others
• Used for Operating systems, embedded systems, performance-critical code
• Why it matters The mother of most modern languages

C++

• Created 1983 by Bjarne Stroustrup at Bell Labs
• Original name "C with Classes"
• Built on C, with ideas from Simula (object-oriented)
• Used for Game engines, browsers, databases, operating systems
• Powers Chrome, Firefox, Windows, Unreal Engine, Adobe products

Java

• Created 1995 by James Gosling at Sun Microsystems
• Original name Oak (after a tree outside Gosling's office)
• Philosophy "Write once, run anywhere" via the JVM
• Built on Influenced by C++, but simplified and safer
• Used for Enterprise software, Android apps, backend systems
• Legacy Spawned Kotlin, Scala, Clojure, Groovy

Go (Golang)

• Created 2009 by Google (Robert Griesemer, Rob Pike, Ken Thompson)
• Ken Thompson Also co-created Unix and C
• Why created Frustration with C++ compile times and complexity
• Philosophy Simplicity, fast compilation, built-in concurrency
• Used for Cloud infrastructure, Docker, Kubernetes, backend services

Rust

• Created 2010 by Graydon Hoare at Mozilla
• Purpose Systems programming without memory safety bugs
• Philosophy Speed of C/C++ with guaranteed memory safety
• Used for Firefox components, Linux kernel, CLI tools, WebAssembly
• Loved Most loved language on Stack Overflow for 7+ years

Swift

• Created 2014 by Apple, led by Chris Lattner
• Built on Replaced Objective-C for Apple development
• Influenced by Objective-C, Rust, Haskell, Ruby, Python
• Used for iOS apps, macOS apps, Apple ecosystem
• Chris Lattner Also created LLVM compiler infrastructure

The Family Tree

Most modern languages trace back to a few ancestors. C (1972) influenced nearly everything. JavaScript (1995) dominates the web. Python (1991) dominates AI. Understanding these roots helps you pick the right tool and learn new languages faster.
