PART 3 Every Programming Language Explained

PART 3 Every Programming Language Explained Rust Everyone's obsessed with right now To fix the exact problem I told you about C C is blazing fast, but it makes you handle all the messy details yourself And one small mistake can crash everything Or leave a security hole wide open Rust's whole pitch is simple: Speed No mistakes Keep that speed, but make those mistakes impossible It does with something called "Borrow Checker" Think of it as a really security guard bouncer that checks your code before it's allowed to run If your code could do anything unsafe, the guard stops it at the door It won't even build until you fix it This is either the best or most annoying part of Rust, depending on your mood The joke is that learning Rust means fighting the compiler You write code, it says no You fix it, it says no again But once it finally lets you through, that code is bulletproof Rust has been voted the most loved language 9 years in a row Not most used Most loved Microsoft Rewriting parts of Windows in it It's going into Linux The US government even put out an official notice telling companies to move off C and C++ towards safer languages like Rust Go Golang Go, sometimes called Golang, came out of Google in 2009 Google's programs got so massive that engineers were sitting around waiting forever just for their code to compile So a few of them built a new language that was fast to run, fast to build, and dead simple to read Most languages give you 10 different ways to do the same thing, which means 10 programmers write it 10 different ways and then argue about it Go deliberately gives you only one way So any two Go developers can reach each others code instantly For big teams, that's gold And you've definitely used it without knowing Go quietly runs a huge chunk of the modern internet's plumbing Docker and Kubernetes, the tools that basically run the cloud and keep apps online at massive scale, are both built in Go Companies like Netflix, Uber, and Cloudflare use Go to handle millions of requests without crashing PHP PHP PHP is the language everyone loves to make fun of It's the punching bag of programming But it also quietly runs most of the internet A website has two halves: The frontend, which you see when you browse a website, and the backend, which is a server, a company's computer sitting somewhere, handling whatever's happening on that website PHP works on the backend When you load a page, PHP is on the server doing the real work: Checking if you're logged in, pulling your posts from the database, building the page just for you Then it sends the finished result to your browser In 1994, a guy named Rasmus Lerdorf just wanted to count visitors on his personal webpage He wasn't building a language He literally said, "I don't like programming" He made a few small tools to code less Other people started using them, and it snowballed into one of the biggest languages on Earth And it took over Even today, around 70% of all websites run on PHP Mostly thanks to WordPress If you've ever built a site, you've probably used WordPress, and WordPress runs on PHP Developers still roast it for being messy But it's pretty simple, free, and does the job HTML and CSS HTML and CSS aren't technically programming languages, and I'll explain why in a second But you've genuinely can't talk about building websites without them, so they've earned a spot Every single website you have ever visited is built on these two HTML came first, invented in 1991 by Tim Berners-Lee, the same guy who literally invented the World Wide Web HTML builds the stage It just lays out what goes where But raw HTML looks awful Plain black text on a white background, like a document from 1995 That's where CSS comes in It's the paint and the styling The colors, the fonts, the spacing, the layout, animations Everything that makes a website actually look good is CSS So HTML builds the skeleton, and CSS dresses it up They're not "real" programming languages because they can't think They can't make decisions or do logic They just describe what a page looks like For a page to actually do anything, you need JavaScript HTML and CSS build the stage JavaScript is the one that performs Look, there are still a lot of coding languages I didn't cover Swift, Kotlin, Ruby, PHP, Bash, R, Solidity, Cobol, Perl, Assembly And a ton of lot more! Every one of these has a story worth telling But if I did that right now, this video would turn into a movie So I'm going to give them their own Part 2, and we'll get into all of them there Another Now coming back to "Vibe Coding" In 2025, AI got genuinely good at writing code for you People started calling it "Vibe Coding" You literally just describe what you want in plain English, and the AI writes it So, "Write me a code for making the flappy bird game!" LET GPTCHAT DO IT English = Programming in 2026 Almost 41% of all new code is being written by AI So do you even need to learn a language anymore? Yes, you do! Because the AI still messes up a lot And when it does, someone has to know what they're looking at to fix it Moreover, learning a programming language helps you to understand the logic behind the code And that logic is basically the base of what makes any programmer a good programmer The job's just shifting a bit! Less about typing out every single line yourself, more about telling the AI what to do and catching it when it's wrong
