Iterate an array of objects

Wondering if anyone knows how to iterate an array of objects like this:

[{
title: 'title1',
description: 'description1'
}, {
title: 'title2',
description: 'description2'
}, {
title: 'title3',
description: 'description3'
}
]

If you want to iterate the titles for example, you can use .map()

const array = [{
title: 'title1',
description: 'description1'
}, {
title: 'title2',
description: 'description2'
}, {
title: 'title3',
description: 'description3'
}
]

array.map(arr => arr.title)

You could use a for-loop like this.

var objArray = [{
title: 'title1',
description: 'description1'
}, {
title: 'title2',
description: 'description2'
}, {
title: 'title3',
description: 'description3'
}];

for(i = 0; i < objArray.length; i++) {
    alert(objArray[i].title);
    alert(objArray[i].description);
}
