How to Merge sorted Arrays in JavaScript

I have three sorted arrays like below

[{name:\"a\"}, {name:\"e\"}, {name:\"i\"}, {name:\"o\"}]

Update:

Seeing as it is current_year this would now be:

const mergeAll = (...arrays) => arrays.reduce(mergeSorted);

Original:

If you're feeling functional this is a perfect place to use reduce.

var mergeAll = function(){
    return Array.prototype.slice.call(arguments).reduce(mergeSorted);
};

example:

var a = [{name:"a"}, {name:"b"}, {name:"m"}, {name:"x"}];
var b = [{name:"a"}, {name:"e"}, {name:"i"}, {name:"o"}];
var c = [{name:"g"}, {name:"h"}, {name:"m"}, {name:"n"}];

console.log(mergeAll(a,b,c).map(function(x){return x.name;}));
