What is the best way to iterate through an array of objects in a react component?

I need help figuring out how to iterate through the array of objects in my React code. Currently, I am using getStaticProps() to fetch data from a mock API server online.

My project is built with nextjs. How can I achieve this using loops like for or while?

import Head from 'next/head'

export async function getStaticProps() {
    const res = await fetch('https://jsonplaceholder.typicode.com/todos')
    const data = await res.json()

    return {
        props: { todos: data }
    }
}

// The getStaticProps function runs before the component is rendered, fetching and providing data for the component to render.

const Todos = ({ todos }) => {
    return (
        <>
            <Head>
                <title>To Do List</title>
            </Head>
            <div>
                <h1>To Do List</h1>
                {todos.map(todoList => (
                    <div key={todoList.id}>
                        <a><h3> 
                            { todoList.title }
                        </h3></a>
                    </div>
                ))}
            </div>
        </>
    );
}

export default Todos;

Answer №1

Feel free to utilize this code snippet

const TodoList = ({ todos }) => {
return (
    <>
        <Head>
            <title>To Do List</title>
        </Head>
        <div>
            <h1>To Do List</h1>
            {todos.map((todo, index) => (
                {index < 50 && <div key={todo.id}>
                    <a href="#"><h3> 
                    { todo.title}
                    </h3> </a>
                </div>}
            ))}
        </div>
    </>
);

}

Answer №2

the array handling requirement must be taken care of

    const handleTodos = ({ todos }) => {
    return (
        <>
            <Head>
                <title>To Do List</title>
            </Head>
            <div>
                <h1>To Do List</h1>
                {todos && todos.length>0 && todos.map(todoList => (
                    <div key={todoList.id}>
                        <a><h3> 
                        {  todoList.title}

                        </h3> </a>
                    </div>
                ))}
            </div>
        </>
    );
}
