Javascript array of object to array of string, simpler way?

Question

I am so used to the syntactic sugar of C# (and not as used to javascript as I want to) that I find this very verbose.

Is there any better way to do this?

var justColumnNames = new Array();    
for( i= 0; i< columnsInfo.length; i++)
{
   justColumnNames[i] = columnsInfo[i].Name;
}

(BTW I have the Extjs available in the page, and I cant really use any other library) Thanks

Answer 1

Ext.each( columnsInfo, function(elem){
    justColumnNames.push(elem.name);
});
