JavaScript is the Worst Thing to Happen to Programming

JavaScript is a mistake. It’s not just bad—it’s actively harmful to the entire programming profession. Every line of JavaScript written is a step backward for humanity.

The Language That Shouldn’t Exist

Designed in 10 Days

JavaScript was created in 10 days by someone who didn’t know what they were doing:

  • No type system: Variables can be anything
  • Inconsistent behavior: == vs === madness
  • Terrible error handling: Silent failures everywhere
  • No standard library: Everything is a hack

// This is legal JavaScript
var x = "5";
var y = 5;
console.log(x == y); // true (WTF?)
console.log(x === y); // false (WTF?)

This is not a programming language—it’s a practical joke.

The Web Development Nightmare

The Framework Churn

Every month, a new JavaScript framework:

  • React: “The future of web development”
  • Vue: “React but better”
  • Angular: “Enterprise-grade complexity”
  • Svelte: “Compile-time magic”
  • Next.js: “Full-stack JavaScript”
  • Nuxt.js: “Next.js but for Vue”

None of them solve the fundamental problem: JavaScript is terrible.

{
  "devDependencies": {
    "webpack": "^5.0.0",
    "babel": "^7.0.0",
    "typescript": "^4.0.0",
    "eslint": "^8.0.0",
    "prettier": "^2.0.0",
    "jest": "^27.0.0",
    "cypress": "^9.0.0"
  }
}

You need 7 tools to write a simple web page.

The Performance Disaster

The Bundle Size Problem

// This simple function
function add(a, b) {
  return a + b;
}

// Becomes this after bundling
!(function (e, t) {
  "object" == typeof exports && "undefined" != typeof module
    ? t(exports)
    : "function" == typeof define && define.amd
      ? define(["exports"], t)
      : t(
          ((e =
            "undefined" != typeof globalThis ? globalThis : e || self).MyLib =
            {}),
        );
})(this, function (exports) {
  "use strict";
  (Object.defineProperty(exports, "__esModule", { value: !0 }),
    (exports.add = function (e, t) {
      return e + t;
    }));
});

A simple function becomes 200 characters of gibberish.

The Runtime Performance

  • Interpreted: Slower than compiled languages
  • Single-threaded: Can’t use multiple cores
  • Garbage collected: Unpredictable pauses
  • Dynamic typing: Runtime type checking overhead

The Security Nightmare

XSS Everywhere

// This is dangerous
document.innerHTML = userInput;

// This is also dangerous
eval(userInput);

// This is also dangerous
new Function(userInput);

JavaScript makes it impossible to write secure code.

The Package Manager Disaster

# This is what happens when you install JavaScript packages
npm install lodash
# Installs 1,000+ dependencies
# Downloads 500MB of code
# Creates security vulnerabilities

One package installs half the internet.

The Developer Experience Hell

The Debugging Nightmare

// Error message: "Cannot read property 'x' of undefined"
// Location: "at line 1"
// Helpful: "Good luck finding the bug"

JavaScript errors are useless.

The Type System Lie

// TypeScript pretends to add types
interface User {
  name: string;
  age: number;
}

// But it's still JavaScript at runtime
const user: User = JSON.parse('{"name": "John"}');
console.log(user.age); // undefined (no error)

TypeScript is a band-aid on a bullet wound.

The Real Problem: The JavaScript Ecosystem

The NPM Hell

  • Left-pad incident: One package broke the internet
  • Security vulnerabilities: Thousands of packages with known issues
  • Dependency hell: Installing one package installs hundreds
  • Version conflicts: Different packages need different versions

The Framework Churn

Every year, JavaScript developers:

  • Learn a new framework: Because the old one is “outdated”
  • Rewrite everything: Because the new framework is “better”
  • Break compatibility: Because “breaking changes are good”
  • Start over: Because “this time it’s different”

The Alternative: Real Programming Languages

WebAssembly

// This is how web development should be done
#[wasm_bindgen]
pub fn add(a: i32, b: i32) -> i32 {
    a + b
}

Fast, safe, and actually works.

Server-Side Rendering

# This is how web development should be done
from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html', data=get_data())

Simple, reliable, and actually works.

The Bottom Line

JavaScript is cancer because it:

  1. Terrible language: Designed in 10 days by amateurs
  2. Performance disaster: Slow, bloated, inefficient
  3. Security nightmare: Impossible to write secure code
  4. Developer hell: Terrible debugging, useless errors
  5. Ecosystem chaos: Framework churn, dependency hell
  6. Vendor lock-in: Can’t escape the JavaScript trap

Stop using JavaScript. Use real programming languages.

Your web applications will be faster, more secure, and easier to maintain.
