On Javascript, how to re-arrange an array

I have the following javascript array var rows.

[
    { email: 'user1@example.com' },
    { email: 'user2@example.com' }
]

Of which, I wanted to make it just...

[
    'user1@example.com',
    'user2@example.com'
]

So, I tried to loop it using forEach

rows.forEach(function(entry) {
    console.log('entry:');
    console.log(entry.email);
});

However, I am stuck with that.

entry:
user1@example.com
entry:
user2@example.com

Any help is appreciated.

Answer 1

You can use Array.prototype.map:

var newArray = oldArray.map(function (obj) {
    return obj.email;
});

Answer 2

here is your solution

var rows =[
    { email: 'user1@example.com' },
    { email: 'user2@example.com' }
];
var yop = [];
rows.forEach(function(entry) {
    yop.push(entry.email);
});

console.log(yop);
