javascript - Pushing an object to beginning of an array




I have this array.



var array = [
{
title:'Fish'
id: 1
},
{

title: 'Meat'
id:2
}
]


It's used in a drop down. I'd like to add an option at the top:



{
title:'All'

id:3
}


How do I push this object to the beginning of the array? If I use push, then it's placed at the end.


Answer



Use the unshift method of the javascript array:



array.unshift({title: 'All', id: 3})
