Practical Examples
Minifizierte Bibliothek-Debugging

Minifizierten JavaScript in lesbaren Code transformieren

BEFORE (Minified JavaScript)
function a(e){return e*2}
AFTER (Beautified JavaScript)
function multiply(number) {\n    return number * 2;\n}

React Component Formatting

Format React components with proper JSX indentation and structure

BEFORE (Minified JavaScript)
const TodoApp=()=>{const[todos,setTodos]=useState([]);const[inputValue,setInputValue]=useState("");const addTodo=()=>{if(inputValue.trim()){setTodos([...todos,{id:Date.now(),text:inputValue,completed:false}]);setInputValue("");}};const toggleTodo=(id)=>{setTodos(todos.map(todo=>todo.id===id?{...todo,completed:!todo.completed}:todo));};const deleteTodo=(id)=>{setTodos(todos.filter(todo=>todo.id!==id));};return(<div className="todo-app"><input value={inputValue}onChange={(e)=>setInputValue(e.target.value)}onKeyPress={(e)=>e.key==="Enter"&&addTodo()}placeholder="Add a todo..."/><button onClick={addTodo}>Add</button><ul>{todos.map(todo=><li key={todo.id}className={todo.completed?"completed":""}><span onClick={()=>toggleTodo(todo.id)}>{todo.text}</span><button onClick={()=>deleteTodo(todo.id)}>Delete</button></li>)}</ul></div>);};
AFTER (Beautified JavaScript)

    const [todos, setTodos] = useState([]);
