I have an array of json objects.
var user =[ { id: 1, name: 'linto', img: 'car' },
{ id: 2, name: 'shinto', img: 'ball' },
{ id: 3, name: 'hany', img: 'kite' } ]
From this is want to remove attribute img from all the elements of the array, so the output looks like this.
var user =[ { id: 1, name: 'linto' },
{ id: 2, name: 'shinto' },
{ id: 3, name: 'hany' } ]
Is there a way to do this in java script.
You can use .map() with Object Destructuring:
let data =[
{ id: 1, name: 'linto', img: 'car' },
{ id: 2, name: 'shinto', img: 'ball' },
{ id: 3, name: 'hany', img: 'kite' }
];
let result = data.map(({img, ...rest}) => rest);
console.log(result);The map() method creates a new array with the results of calling a provided function on every element in the calling array.
You can use map() in the following way:
var user =[ { id: 1, name: 'linto', img: 'car' },
{ id: 2, name: 'shinto', img: 'ball' },
{ id: 3, name: 'hany', img: 'kite' } ]
user = user.map(u => ({id: u.id, name: u.name}));
console.log(user);
map() is designed to iterate over all the array items and you can manipulate the items based on some condition. If you want to filter out some items then you can use filter():)
