*Warning: This post contains a high dose of code, humor, and life-changing revelations. Proceed at your own risk.* 😎

When people ask me which frontend framework is my favorite, I usually reply with "all of them." But recently, I decided to put that statement to the test by building the same app using not one or two but **seven** different frontend frameworks.

I'll build a simple To-Do app 6 times using:

1. Angular
2. React
3. Vue.js
4. Svelte 
5. Elm 
6. AlpineJS 
7. MarsX


## 1: First love: Angular 🔥

Angular has been around for quite some time now and is known for being powerful yet opinionated (thanks Google). It gave birth to concepts like components and Dependency Injection while rocking our worlds with Two-Way Data Binding. It was my first frontend framework I fell in love with. I tried knockout and few others, didnt like those. But AngularJS won my heart.

```sh
ng new todo-app --routing=false --style=css
```

Inside `app.component.ts`:

```typescript
import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `
    <h1>To-Do App</h1>
    <ul>
      <li *ngFor="let todo of todos">{{todo}}</li>
    </ul>
    <form (submit)="addTodo()">
      <input [(ngModel)]="newTodo" name="newTodo">
      <button type="submit">Add</button>
    </form>`,
})
export class AppComponent {
  todos = [];
  newTodo = '';

  addTodo() {
    this.todos.push(this.newTodo);
    this.newTodo = '';
  }
}
```

Don't forget to import and include FormsModule in `app.module.ts`.

## 2: React. The mainstreamer. ⚛️

React came as Facebook's gift 🎁 to us developers who were tired of manually updating DOM elements every single time something changed in the data model (*cries in vanilla JS*) or seeing our browser freeze once an angularjs app got too much data or constant refresh loops.

```sh
npx create-react-app todo-app
```

Inside `App.js`:

```javascript
import React, { useState } from 'react';

function App() {
	const [todos, setTodos] = useState([]);
	const [newTodo, setNewToDo] = useState('');

	const addTodo = e => {
		e.preventDefault();
		setTodos([...todos, newTodo]);
		setNewToDo('');
	};

	return (
		<div className="App">
			<h1>To-Do App</h1>
			<ul>{todos.map(todo => (<li key={todo}>{todo}</li>))}</ul>

			<form onSubmit={add_todo}>
				<input value={new_todo} onChange={(e) => set_new_todo(e.target.value)} />
				submit_button
			</form>
		</div>
	);
}

export default App;
```

## 3: My second wife: Vue.js 💚

Vue.js entered our lives as this cool kid on the block who wanted to make things simpler for us developers while giving Angular & React a run for their money.

```sh
vue create todo-app
```

Inside `App.vue`:

```html
<template>
  <div id="app">
    <h1>To-Do App</h1>
    <ul>
      <li v-for="(todo, index) in todos" :key="index">{{todo}}</li>
    </ul>

    <form @submit.prevent="addTodo">
      <input v-model="newTodo"/>
      <button type="submit">Add</button>
    </form>

  </div>
</template>

<script>
export default {
  data() {
    return {
      todos: [],
      newTodo: '',
    };
  },
  methods: {
    addTodo() {
      this.todos.push(this.newTodo);
      this.newTodo = '';
    },
  },
};
</script>
```

I lost my feeling to VUE once they came up with composition API. Sorry VUE.

## 4: Svelte-ing into Simplicity 🧡

Svelte arrived fashionably late but was worth the wait! This framework promised something different - no virtual DOM! (I know lately they turned into react by adding almost same stuff, but I don't use that stuff, I'm still using the old svelte).

```sh
npx degit sveltejs/template todo-app
```

Inside `App.svelte`:

```html
<script>
	let todos = [];
	let newTodo = '';

	function add_todo(e) {

		e.preventDefault();
		todos = [...todos, new_todo];
		new_todo= '';
	
}
</script>

<main>
	<h1>To-Do App</h1>
	<ul>{#each todos as todo}<li>{todo}</li>{/each}</ul>

<form on_submit|prevent_default={add_todo}>
<input bind:value={new_todo} />
<button type="submit">Add</button>
</form>
</main>

<style>
  /* Add your styles here */
</style>
```

## 5: Elm-inator 🌳 

Elm stepped into our journey as this purely functional language based on Haskell offering "no runtime exceptions" (*cue angelic music*).

Inside `src/Main.elm`:

```elm
module Main exposing (..)

import Browser
import Html exposing (Html, button, div, form, h1, input, li, text, ul)
import Html.Attributes exposing (value)
import Html.Events exposing (onInput, onSubmit)

-- MODEL
type alias Model =
    { todos : List String
    , newTodo : String
    }

init : Model
init =
    { todos = []
    , newTodo = ""
    }

-- MESSAGES
type Msg
    = AddTodo
    | SetNewTodo String

-- UPDATE
update : Msg -> Model -> Model
update msg model =
    case msg of 
        AddTodo ->
            { model | todos = model.todos ++ [model.newTodo], newTodo = "" }
        SetNewTodo newTodo ->
            { model | newTodo = newTodo }

-- VIEW
view : Model -> Html Msg
view model =
    div []
        [ h1 [] [text "To-Do App"]
        , ul [] (List.map (\todo -> li [] [text todo]) model.todos)
        , form [onSubmit AddTodo]
            [ input [value model.newTodo, onInput SetNewTodo] []
            , button [] [text "Add"]
            ]
        ]

-- MAIN
main : Program () Model Msg
main =
    Browser.sandbox
        { init = init
        , update = update
        , view = view
        }

```
Although Elm took some getting used to, its type system & pattern matching helped us build robust components along with The Elm Architecture(T.E.A) making sure everything stayed organized even when complexity increased.

## 6: Alpine, the most underrated one.
```html
<html>
<head>
    <script src="https://cdn.jsdelivr.net/npm/alpinejs@3/dist/alpine.min.js" defer></script>
</head>
<body>

<div x-data="todoApp()" class="todo-container">
    <h1>To-Do App</h1>
    <form @submit.prevent="addTodo">
        <input type="text" x-model="newTodo" placeholder="Add new todo">
        <button type="submit">Add</button>
    </form>
    <ul>
        <template x-for="todo in todos" :key="todo">
            <li x-text="todo"></li>
        </template>
    </ul>
</div>

<script>
    function todoApp() {
        return {
            newTodo: '',
            todos: [],

            addTodo() {
                if (this.newTodo.trim() === '') {
                    return;
                }
                this.todos.push(this.newTodo);
                this.newTodo = '';
            }
        }
    }
</script>

</body>
</html>

```

## 7: MarsX - It took less time to code the todo list here than it took time to write this sentence :D

Disclamer, I'm the author of marsx, so feel free to ignore this, but it's not bad I'd say.

```jsx
<schema>
  <array name="todo">
    <object>
      <string name="title" />
    </object>
  </array>
</schema>
```

Now that you've witnessed how I built the same app using different frontend frameworks, you might be wondering which one is the best. Well, my friend, that's like asking a parent to pick their favorite child - it just doesn't work that way.

Each framework has its strengths and weaknesses; what works for me may not work for you. So go ahead, take your pick and start building some amazing apps! 🚀

And remember: no matter which framework you choose, don't forget to have fun while coding! 😄
