I built the same app 6 times! Which JS Framework is best?

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

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 = '';
  }
}

npx create-react-app todo-app

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;
