Filter array of objects by object key

Question

I have an array of objects in Javascript:

var List = [
            {
                employee:\'Joe\',
                type:\'holiday\',
            },
              


        

Answer 1

var joe = List.filter(function(el){
 return el.employee === "Joe"
});

var jerry = List.filter(function(el){
 return el.employee === "Jerry"
});

This uses Array.prototype.filter and will work in IE9 and up + all recent Chrome/Firefox/Safari/Opera releases.

If you don't know the names in advance then you can create a map var names = {};

for(var i =0; i

}

As a side note, Javascript convention is to only capitalize the first letter of a variable for constructors. So List should probably be list.
