Intro to Programming Languages Used Today

Every app, game, and website you touched today runs on a programming language — here is your friendly tour of all of them.

Intro to Programming Languages Used Today by Cosmo is a warm, illustrated tour of the languages behind the modern world: Python, JavaScript, TypeScript, Java, C#, C++, C, SQL, PHP, Go, Rust, Swift, Kotlin, and R — plus an honest explainer on HTML and CSS, and why HTML is markup, not a programming language. For each language you will learn what it is for, where you already met it today, see a tiny real example of it, and find out who is hiring for it.

Not sure where to start? A full chapter helps you choose your first language by goal — web, apps, games, data, or automation — and the closing chapter lays out a first-90-days roadmap, so you finish the book with a plan, not just trivia.
