Objects with Array in Java Script | with source code

Array object

The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Simple Example:

const myTodo =['Buy bread','go gym', 'work']

//indexOf() print the index of an element within an array.

 console.log(myTodo.indexOf('Buy bread'));

Creating a simple TODO :

//array with object

const newTodos = [{

    title:'Buy Bread',

    isDone:false,

},{

    title:'go gym',

    isDone:false,

},{

    title:'work',

    isDone:true,

}]

//findindex2

const index=newTodos.find(function (todo) {

    return todo.title==='go gym'

})

console.log(index);
