Convert JavaScript array into array of object

What is the fastest algorithm for getting from something like this:

var array = [ 'a','b','c','d','e' ];

to something like this:

[{label:'a',value:'a'},{label:'b',value:'b'},{label:'c',value:'c'},{label:'d',value:'d'},{label:'e',value:'e'}]

    You can use array.map function to covert the array into required object. In your case something like this would generate the required result

    var array = [ 'a','b','c','d','e' ];
var result = array.map(function (element) {
    return {
        'label': element,
        'value': element
    };
});

    you can refer to the full documentation for map here https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map
